Transaction Certificates in Fashion: MOQ, Chain of Custody and Anti-Greenwashing Rules

Transaction Certificates in fashion are often requested too late.

A brand selects a certified fabric, develops a prototype, confirms a small production run and only then asks:

“Will we receive a Transaction Certificate?”

At that point, the certification pathway may already have been interrupted.

The quantity may be below the technical MOQ.
The chosen processing partner may not be covered by the relevant certification.
The fabric lot may not have the required documentation.
The garment maker may sit outside the applicable Chain of Custody.
The brand may not be authorised to use the certification logo or describe the finished garment as certified.

A Transaction Certificate, commonly abbreviated as TC, is not a generic sustainability certificate. It is transaction-specific evidence used by certain textile certification systems to connect defined certified goods with specific sellers, buyers, quantities and shipment information.

At ARNIA TEXTILE FASHION, certified material pathways are evaluated article by article, lot by lot and project by project. Technical MOQ, Chain of Custody, documentation, production processes and the intended marketing claim must be reviewed before production—not after it.

This guide explains:

• what a textile Transaction Certificate proves;
• what it does not prove;
• the difference between a Scope Certificate and a Transaction Certificate;
• how Chain of Custody works;
• why MOQ matters;
• which textile standards use TCs and which use different evidence;
• the strengths and limitations of the principal textile certification systems;
• how fashion brands can prevent unsupported sustainability claims and greenwashing.

Quick Answer: What Is a Transaction Certificate in Fashion?

A textile Transaction Certificate is a document issued or validated by an approved Certification Body for a specific transaction involving certified goods.

Under GOTS, a Transaction Certificate verifies certified products and supports traceability by listing product and shipment information and by confirming integrity through volume reconciliation.

A TC normally connects:

• the certification standard;
• the certified seller;
• the buyer or consignee;
• the relevant Scope Certificate;
• the product or material;
• the certification claim;
• the certified quantity;
• invoice or shipment references;
• the date and Certification Body;
• the material-accounting or volume-reconciliation process.

A Transaction Certificate does not automatically prove that:

• the entire brand is sustainable;
• every product sold by the supplier is certified;
• the final garment is certified;
• the certification logo can be used;
• every trim and component is certified;
• the product has a lower carbon footprint;
• all environmental and social impacts have been assessed;
• the product is legally compliant in every sales market.

The safest definition is:

A Scope Certificate proves that an organisation is certified for a defined scope. A Transaction Certificate proves that a specific certified transaction is covered. Neither document should be interpreted beyond its actual scope.

---

1. Scope Certificate vs Transaction Certificate

Scope Certificates and Transaction Certificates answer two different questions.

What is a Scope Certificate?

A Scope Certificate, or SC, confirms that an organisation has been audited and certified for defined:

• locations;
• activities;
• processes;
• product categories;
• materials;
• standards;
• validity dates.

It answers:

“Is this company certified to perform these activities under this standard?”

It does not answer:

“Is the exact fabric in this delivery certified?”

A supplier may hold a valid Scope Certificate but also sell conventional, non-certified or differently certified products.

What is a Transaction Certificate?

A Transaction Certificate answers a narrower question:

“Does this specific commercial transaction involve goods covered by the applicable certification pathway?”

GOTS advises buyers to obtain a TC for the specific shipment or delivery rather than relying only on the supplier’s general certification status. Textile Exchange likewise provides separate public authentication systems for Scope Certificates and Transaction Certificates.

Why the difference matters

A Scope Certificate demonstrates capability.

A Transaction Certificate demonstrates the certified status of defined goods moving through a defined transaction.

A screenshot of a supplier certificate is therefore not sufficient evidence for every fabric, colour, lot or delivery.

2. Which Document Proves What?

These documents can complement each other, but they are not interchangeable.

---

3. What Information Should a Transaction Certificate Contain?

Formats vary according to the standard and Certification Body, but a professional TC review will usually examine the following fields.

Certification information

• certification standard;
• applicable standard version;
• TC number;
• issue date;
• Certification Body;
• seller’s certification details;
• validity and scope references.

Commercial parties

• certified seller;
• buyer;
• consignee, where different;
• addresses and identification details;
• legal ownership relationship.

Product information

• product category;
• article or style reference;
• material description;
• fibre composition;
• organic or recycled content;
• certified claim;
• lot or batch information where applicable.

Transaction information

• invoice number;
• invoice date;
• shipment date;
• purchase or sales reference;
• units of measure;
• gross and net quantities;
• country or destination;
• related shipment documents.

Integrity information

• input claims;
• output claims;
• material-accounting method;
• volume reconciliation;
• any permitted blending or mass-balance information;
• certification-body approval.

The buyer should be able to connect the TC to the real purchase order, invoice, shipment, article, colour and quantity.

A TC that cannot be connected to the actual goods should not be treated as reliable product evidence.

---

4. What Is Chain of Custody in Textile Certification?

Chain of Custody is the documented system used to preserve the identity, accounting and certification status of a material as it moves through the supply chain.

A simplified fashion Chain of Custody may involve:

Fibre source → ginning or first processing → spinning → weaving or knitting → dyeing or printing → finishing → textile converter or trader → garment manufacturing → brand → retailer

At each relevant stage, the organisation may need to:

• hold the correct certification;
• identify certified material;
• segregate or correctly account for it;
• keep purchasing and sales records;
• control subcontractors;
• reconcile input and output quantities;
• pass the correct claim to the next organisation;
• maintain authorised documentation.

Textile Exchange’s Content Claim Standard is the Chain of Custody foundation for its standards. It verifies product flow, documentation, volume reconciliation and material segregation across production stages.

Chain of Custody follows responsibility, not only physical distance

One important point is that certification can be affected by:

• physical possession;
• legal ownership;
• transformation of the material;
• relabelling;
• repacking;
• resale;
• subcontracting.

A trader or brand may never touch the goods physically but may still affect the Chain of Custody because it buys, owns and resells them. Under Textile Exchange rules, traders and brands that take legal ownership and resell certified goods in B2B transactions may require certification, subject to defined exemptions.

This is why a brand cannot simply ask:

“Is the mill certified?”

It must ask:

“Is the entire relevant route for our intended claim covered?”

---

5. Segregation, Controlled Blending and Mass Balance

Not every certification system tracks material in exactly the same way.

Segregation

Certified material is kept physically separate from non-certified material.

This offers a strong connection between the material entering the supply chain and the material in the final output.

It normally requires:

• separate identification;
• controlled storage;
• production planning;
• machine and line management;
• documented transfers;
• inventory control.

Controlled blending

Certified and non-certified inputs may be blended according to defined rules, with the composition and accounting controlled.

The final claim must reflect the actual permitted composition.

Mass balance

Mass balance tracks equivalent certified volumes through an accounting system, but the exact certified physical molecules or fibres may not be present in every individual product carrying the related sourcing claim.

Better Cotton states this distinction very clearly: under its mass-balance model, a Better Cotton order does not equal a physically traceable Better Cotton product. Physical Better Cotton instead uses segregation or controlled-blending models.

ISCC PLUS also permits physical segregation, controlled blending and mass balance for alternative feedstocks such as recycled, bio-based and circular materials.

Why brands must understand the model

A mass-balance claim is not necessarily weak or illegitimate. It supports scale and verified volume accounting.

But it must not be communicated as if it proved physical identity when it does not.

The Chain of Custody model determines what the brand can honestly say.

---

6. Where Can the Chain of Custody Break?

A Chain of Custody can be interrupted even when the original fabric was genuinely certified.

Common break points include:

An uncertified downstream processor

The fabric moves from a certified mill to an uncertified printer, dyer, finisher, embroiderer or garment maker.

An unapproved subcontractor

A certified company sends part of the work to a workshop that is not covered by the permitted certification arrangement.

An uncertified trader or brand

Legal ownership changes, but the new entity is not covered where certification is required.

Mixing or inventory errors

Certified and conventional goods are mixed without the required segregation or accounting controls.

Missing incoming documentation

The supplier has a valid Scope Certificate but cannot demonstrate the certified status of the material received.

Incorrect output claim

The material is certified under one category, but it is sold using a broader or different claim.

Uncontrolled relabelling or repacking

The product identity changes without the necessary records or approval.

Certification planned after production

The brand decides to request certification only after the fabric or garment has already passed through uncontrolled stages.

A Transaction Certificate cannot automatically repair a Chain of Custody that was never correctly planned.

---

7. Why Certified Fabric Does Not Automatically Mean Certified Garment

A certified fabric and a certified garment are two different claim levels.

Consider this example:

1. A certified mill produces a GOTS fabric.
2. The fabric is sold with valid transaction documentation.
3. The fabric is sent to an uncertified garment manufacturer.
4. The garment is cut, sewn, labelled and packed outside the applicable certified route.
5. The brand describes the finished garment as “GOTS certified”.

The first two steps may be valid.

The final claim may not be.

The certification of the fabric does not automatically extend across every downstream activity.

The correct analysis separates three levels:

Level 1 — Certified organisation

Is the supplier certified for the relevant process and product category?

Level 2 — Certified transaction

Is the specific fabric, lot and quantity covered by transaction documentation?

Level 3 — Final product claim

Does the complete route allow the brand to describe or label the finished garment as certified?

For the complete distinction, read:

GOTS, GRS and FSC Fabrics: Why Certified Fabric Does Not Automatically Mean Certified Garment

---

8. Which Certification Systems Use Transaction Certificates?

The word “TC” should not be applied indiscriminately to every sustainability system.

GOTS

GOTS uses Transaction Certificates to connect GOTS-certified products with specific transactions, shipment details and volume reconciliation.

GOTS Version 8.0 was released on 1 March 2026 and strengthens supply-chain accountability, due diligence, chemicals, climate criteria and circularity requirements.

GRS, RCS and OCS

Textile Exchange standards use Scope Certificates and Transaction Certificates under the Content Claim Standard Chain of Custody framework.

For GRS and RCS, Textile Exchange has also introduced eTransactions through eTrackit. Within eTrackit, eTransactions replace conventional TCs for transactions processed through that system and combine peer validation with Certification Body approval.

FSC ®

FSC does not generally rely on a GOTS- or Textile Exchange-style TC as its standard proof for each sale.

FSC Chain of Custody certification requires forest-based material to be identified and tracked, with purchase, production and sales records retained. Certified claims are passed through sales and delivery documents by organisations holding the appropriate FSC Chain of Custody status.

Therefore, brands should not automatically ask:

“Can you issue an FSC TC?”

The more accurate request is:

“Can you confirm the applicable FSC Chain of Custody route and provide sales documents carrying the correct FSC claim?”

ECOVERO™

LENZING™ ECOVERO™ is a branded viscose-fibre system rather than a generic textile TC standard.

Lenzing describes ECOVERO™ fibres as coming from certified or controlled wood sources, carrying a molecular marker for identification and traceability and being certified under the EU Ecolabel at fibre level. This does not automatically certify every downstream fabric process or finished garment.

OEKO-TEX®

OEKO-TEX® uses certificates and product or facility labels according to the specific system.

STANDARD 100 addresses harmful-substance testing.
STeP addresses production facilities.
MADE IN GREEN combines harmful-substance testing, responsible production conditions and product traceability.

These are not interchangeable with GOTS or GRS Transaction Certificates.

---

9. Paper TC, Digital TC and eTransaction

Fashion companies should not assume that all valid transaction evidence must always be a PDF.

Conventional Transaction Certificate

The traditional model involves:

1. shipment of certified goods;
2. application by the certified seller;
3. verification by the Certification Body;
4. review of inputs, quantities and shipment documents;
5. issuance of a TC;
6. delivery to the buyer.

Digital authentication

Textile Exchange allows Scope Certificates to be checked through its certified-company database and post-October 2022 Transaction Certificates through its transaction-authentication system.

eTransactions

Textile Exchange’s eTrackit platform enables certified material transactions to be digitally validated. GRS and RCS eTransactions have been live since September 2024.

The terminology in purchase orders should therefore allow for:

“Valid Transaction Certificate or approved digital transaction evidence under the applicable standard.”

This avoids rejecting valid evidence merely because it is not a conventional PDF.

---

10. Is There a Universal MOQ for a Transaction Certificate?

No single universal number applies to every product, every standard and every supply chain.

The certification standard defines the requirements for certification integrity.

The practical MOQ is often created by the production route.

It may depend on:

• minimum yarn purchase;
• greige availability;
• weaving or knitting setup;
• dye-bath capacity;
• printing-table or machine setup;
• colour separation;
• finishing minimums;
• machine cleaning;
• production segregation;
• minimum economical run;
• certified subcontractor availability;
• laboratory testing;
• certification administration;
• documentation and Certification Body fees;
• volume-reconciliation feasibility.

A technically valid certified route may therefore exist in principle but be commercially or operationally impossible at a very small quantity.

ARNIA’s indicative technical planning references

The following figures are ARNIA operational planning references, not universal minimums established identically by the standards:

Final feasibility depends on:

• selected article;
• fibre composition;
• colour or print;
• process route;
• certified operator availability;
• lot and material availability;
• segregation requirements;
• intended final claim;
• brand certification status;
• final market;
• buyer documentation requirements.

ARNIA’s Sustainable Textiles page already states that TC availability is confirmed only for eligible production lots meeting the applicable technical minimums, documentation, segregation and Chain of Custody requirements.

Why metres do not equal garments

A 300-metre textile MOQ does not mean a 300-piece garment MOQ.

Garment yield depends on:

• fabric width;
• garment category;
• size range;
• pattern layout;
• print direction;
• matching requirements;
• cutting waste;
• defects and tolerances;
• number of colourways.

A small Cut & Sew MOQ and a certified textile MOQ are separate industrial constraints.

---

11. Why Samples and Prototypes Usually Cannot Carry a TC

A prototype may use only three or five metres of fabric.

That does not normally justify:

• a dedicated certified weaving run;
• a separate dye bath;
• machine cleaning;
• material segregation;
• production reconciliation;
• Certification Body review;
• a complete downstream certified route.

The prototype can still be developed responsibly.

It can use:

• a documented fabric;
• an existing certified material;
• a traceable stock-supported quality;
• composition and technical data;
• chemical-compliance testing;
• selected ethical partners.

But the brand must distinguish between:

Responsible sample

A sample developed through considered sourcing and controlled partners.

Sample made with a certified input

A prototype using material that originated from a certified lot.

Certified final product

A product covered by the complete eligible certification and claim pathway.

These phrases are not equivalent.

At ARNIA, it is not technically responsible to promise Transaction Certificates for prototypes, sampling or undersized test lots where the required Chain of Custody, segregation and documentation cannot be implemented.

---

12. Transaction Certificates and Anti-Greenwashing Rules

A TC is not only an administrative document.

It can become part of the evidence used to substantiate a sustainability claim.

But the evidence must match the exact claim.

From 27 September 2026, Directive (EU) 2024/825 strengthens European consumer protection against misleading environmental communication. Italy transposed the directive through Legislative Decree No. 30 of 20 February 2026.

The new framework addresses practices including:

• sustainability labels not based on an eligible certification scheme or public authority;
• generic environmental claims without recognised supporting performance;
• claims about the whole product or business based only on one limited aspect;
• certain climate-neutrality claims based on greenhouse-gas offsetting;
• legal requirements presented as unique environmental benefits.

What this means for fashion brands

A TC for a recycled fabric lot cannot substantiate:

“Our entire collection is sustainable.”

A GOTS fabric TC cannot automatically substantiate:

“Our brand is GOTS certified.”

An FSC-based viscose claim cannot automatically substantiate:

“This is an environmentally friendly garment.”

An OEKO-TEX® harmful-substance test cannot substantiate:

“This product is organic.”

Each document supports a defined proposition.

Anti-greenwashing compliance begins by making the claim no broader than the evidence.

 

---

13. Claim Matrix: Risky Wording vs Evidence-Based Wording

The exact wording must always be validated against the applicable standard and market. The following examples illustrate the logic.

The strongest sustainability claim is not the most ambitious sentence.

It is the most precise sentence the brand can prove.

---

14. Textile Environmental Certifications: What They Cover, Their Strengths and Their Limits

There is no single certification that answers every environmental, chemical, social, traceability and product-performance question.

The principal systems belong to different categories:

• organic or recycled content standards;
• Chain of Custody standards;
• forest-sourcing standards;
• chemical-safety systems;
• responsible-production systems;
• ecolabels;
• mass-balance programmes;
• proprietary fibre-verification systems.

A responsible sourcing strategy may require more than one.

---

15. Organic and Recycled Material Standards

GOTS — Global Organic Textile Standard

What it covers

GOTS addresses textiles made with certified organic fibres and includes processing, chemical, environmental, human-rights and social criteria across the relevant textile supply chain.

GOTS-labelled products must contain at least 70% certified organic fibres. The “organic” label grade requires at least 95%.

Main advantages

• broad processing standard;
• organic fibre integrity;
• chemical restrictions;
• social and human-rights criteria;
• independent certification;
• Chain of Custody;
• recognisable consumer label;
• Transaction Certificates.

Main limitations

• technically and administratively demanding;
• not suitable for every fibre or blend;
• strict downstream claim requirements;
• higher certification and segregation complexity;
• often difficult for micro-lots;
• buying GOTS fabric alone does not certify the final garment.

Best use

Brands seeking a robust organic textile route from eligible fibres through controlled processing and final product claims.

---

OCS — Organic Content Standard

What it covers

OCS uses third-party certification to verify the amount of organically grown material in a final product and relies on Textile Exchange’s Content Claim Standard Chain of Custody.

It does not address chemical use or broader social and environmental processing conditions beyond organic-content integrity.

Main advantages

• clear verification of organic content;
• simpler and more focused than GOTS;
• useful where content verification is the primary requirement;
• recognised Chain of Custody structure.

Main limitations

• does not certify comprehensive chemical management;
• does not assess wider social criteria;
• does not by itself demonstrate lower overall lifecycle impact;
• should not be communicated as equivalent to GOTS.

Best use

Projects that need verified organic content but do not require a comprehensive organic textile processing standard.

---

GRS — Global Recycled Standard

What it covers

GRS certifies recycled-material content and Chain of Custody and adds social, environmental and chemical requirements for processing.

GRS can operate as a B2B certification tool from 20% recycled content, while consumer-facing GRS product claims generally require at least 50% recycled content.

Main advantages

• recycled-content verification;
• independent Chain of Custody;
• processing requirements;
• social and environmental criteria;
• chemical restrictions;
• recognised B2B and consumer claim system;
• TC or eTransaction evidence.

Main limitations

• recycled content alone does not prove lower total environmental impact;
• does not automatically prove durability or recyclability;
• supply-chain certification can be complex;
• minimum claim thresholds must be understood;
• downstream brand and labelling requirements still apply.

Best use

Recycled polyester, recycled polyamide and other eligible recycled-material projects requiring robust content and process verification.

---

RCS — Recycled Claim Standard

What it covers

RCS verifies recycled material and Chain of Custody but is less extensive than GRS because it does not include the same additional social, environmental and chemical-processing requirements.

Main advantages

• focused recycled-content verification;
• simpler than GRS;
• useful for products that do not need the broader GRS processing framework;
• supports transaction evidence and Chain of Custody.

Main limitations

• narrower environmental and social scope;
• does not demonstrate comprehensive chemical management;
• should not be presented as equivalent to GRS;
• does not prove overall product sustainability.

Best use

Projects where verified recycled content is the primary requirement.

---

16. Forest-Based and Cellulosic Material Systems

FSC ® — Forest Stewardship Council

What it covers

FSC Chain of Custody verifies the controlled movement of eligible forest-based material from certified, controlled or reclaimed sources through processing and sale.

In textiles, it can be relevant to viscose, modal, lyocell, acetate and other forest-based material routes.

Main advantages

• recognised forest-origin and Chain of Custody system;
• supports responsible forestry;
• material tracking;
• core labour requirements;
• controlled sales-document claims;
• established trademark rules.

Main limitations

• does not certify every downstream textile environmental impact;
• does not by itself assess dyeing, finishing or full garment sustainability;
• it uses FSC claims and CoC documentation, not necessarily a conventional textile TC;
• logo and promotional use require the correct certification or licensing route.

Best use

Cellulosic textile projects where responsible forest sourcing is a material priority.

---

LENZING™ ECOVERO™

What it covers

ECOVERO™ is a branded viscose fibre with controlled or certified wood sourcing, molecular-marker traceability and EU Ecolabel certification at fibre level.

Main advantages

• recognisable branded fibre;
• molecular identification;
• controlled wood sourcing;
• EU Ecolabel at fibre level;
• useful communication support when correctly licensed.

Main limitations

• it is not a universal certification of the finished fabric or garment;
• it does not automatically cover downstream dyeing, printing, finishing or garment making;
• brand and product claims remain subject to Lenzing’s rules and real fibre content;
• no assumption of a GOTS-style TC should be made.

Best use

Viscose products requiring a defined branded-fibre pathway and verified fibre identity.

---

17. Chemical Safety and Responsible Processing Systems

OEKO-TEX® STANDARD 100

What it covers

STANDARD 100 certifies that the tested textile article has passed requirements for harmful substances.

Main advantages

• strong product-safety relevance;
• applicable from yarn to finished product;
• useful for skin-contact and sensitive categories;
• recognisable label;
• article-specific testing.

Main limitations

• does not prove organic or recycled content;
• does not automatically verify fibre origin;
• does not by itself certify the entire environmental footprint;
• should not be described generically as “sustainable certification”.

ARNIA is not an OEKO-TEX®-certified company. Tests aligned with STANDARD 100 Class I or II can, however, be evaluated on request for defined projects, alongside REACH and brand RSL/MRSL requirements.

---

OEKO-TEX® MADE IN GREEN and STeP

What they cover

STeP certifies textile and leather production facilities under defined responsible-production requirements.

MADE IN GREEN identifies products tested for harmful substances and produced under sustainable and socially responsible conditions, with supply-chain traceability.

Main advantages

• product-safety and facility-level integration;
• supply-chain traceability;
• environmental and social production criteria;
• consumer-facing label;
• useful for finished products.

Main limitations

• requires participation from relevant facilities;
• more complex than a single product test;
• does not automatically verify organic or recycled content;
• can require combination with other material standards.

---

bluesign / bluepass

From April 2026, bluesign began replacing the previous bluesign® PRODUCT and bluesign® APPROVED designations with bluepass labels for consumer products, articles and chemical products.

bluepass assesses processes across restricted substances, material traceability, water, energy, waste, emissions, worker safety, emergency preparedness and social responsibility. QR codes connect labels to bluesign-controlled verification pages.

Main advantages

• strong chemical-input control;
• production-process assessment;
• resource and emissions management;
• occupational safety;
• on-site evaluation;
• verified data and QR-supported claims.

Main limitations

• does not automatically verify organic or recycled content;
• works through the bluesign partner and assessed-input ecosystem;
• implementation can be demanding for smaller supply chains;
• needs to be combined with material-content standards where relevant.

---

ZDHC Roadmap to Zero

ZDHC focuses on chemical management in textile, apparel, leather and footwear supply chains.

Its tools include:

• Manufacturing Restricted Substances List;
• chemical-inventory conformance;
• Supplier to Zero;
• InCheck;
• wastewater and output monitoring;
• continuous-improvement frameworks.

Main advantages

• detailed chemical-management framework;
• useful for wet-processing suppliers;
• widely recognised by major brands;
• supports input, process and output controls;
• protects workers, consumers and ecosystems.

Main limitations

• ZDHC is not a general product sustainability certification;
• it does not certify organic or recycled content;
• Supplier to Zero primarily evaluates facility chemical-management maturity;
• a ZDHC-aligned facility does not automatically create a certified garment.

ZDHC should therefore be presented as a chemical-management and supplier-performance system, not as a substitute for GOTS, GRS or a product certification.

---

18. Product-Level Environmental Labels

EU Ecolabel for Textiles

The EU Ecolabel is the European Union’s voluntary Type I environmental label.

For textile products, it addresses:

• more sustainable fibre production;
• less polluting production processes;
• restrictions on hazardous substances;
• product durability and fitness for use.

The current textile criteria have been extended to 31 December 2028 while revision work continues.

Main advantages

• lifecycle-based approach;
• official public-authority label;
• environmental and technical-performance criteria;
• hazardous-substance restrictions;
• durability requirements;
• high credibility under EU consumer rules.

Main limitations

• application and evidence requirements can be substantial;
• less common in some luxury B2B textile segments;
• specific product criteria must be met;
• does not replace other content or Chain of Custody standards where those claims are needed.

Best use

Finished textiles or garments seeking a broad, official product-level environmental label for the European market.

---

19. Sourcing, Mass-Balance and Alternative-Feedstock Systems

Better Cotton

Better Cotton supports improved cotton-farming practices and offers both mass-balance and Physical BCI Cotton pathways.

Main advantages

• large-scale cotton programme;
• supports farmer training and improved practices;
• scalable mass-balance model;
• physical traceability pathways now available;
• established claims framework.

Main limitations

• mass-balance sourcing does not prove that the cotton physically present in the specific garment is Better Cotton;
• product-level claims depend on membership, certification and the selected Chain of Custody model;
• old logos and claims must not be reused without checking current rules;
• it should not be described as organic cotton unless separately verified.

---

ISCC PLUS

ISCC PLUS certifies alternative feedstocks, including recycled, bio-circular, bio-based and renewable-energy-derived materials.

It can use:

• physical segregation;
• controlled blending;
• mass balance.

Main advantages

• relevant to chemically recycled and bio-based synthetics;
• broad feedstock coverage;
• third-party certification;
• material accounting;
• on-product claim routes;
• expanding relevance in textiles.

Main limitations

• mass-balance claims require careful explanation;
• the certified attribute may be linked through accounting rather than physical molecule-level identity;
• final claim eligibility depends on certification or licensing;
• does not automatically demonstrate every lifecycle benefit.

Best use

Circular and bio-based polymer pathways where conventional mechanical-recycling standards may not fit the feedstock model.

---

20. Which Textile Certification Should a Brand Choose?

The correct question is not:

“Which certification is best?”

The correct question is:

“What exactly do we need to prove?”

Many credible products combine systems.

For example:

• GOTS plus laboratory performance testing;
• GRS plus OEKO-TEX® STANDARD 100;
• FSC-based viscose plus chemical-compliance documentation;
• ECOVERO™ plus an audited downstream production route;
• ISCC PLUS feedstocks plus product-performance and chemical testing.

Certification selection should follow the product and claim strategy—not the marketing calendar.

---

21. 2026 Standards Update: Why Buyers Must Verify the Current Version

Certification systems evolve.

A certificate or claim guide used three years ago may no longer be sufficient.

GOTS 8.0

GOTS Version 8.0 was released on 1 March 2026, strengthening supply-chain accountability, mandatory due diligence, chemical and climate criteria and circularity requirements.

Textile Exchange eTransactions

GRS and RCS eTransactions are active through eTrackit, meaning digital transaction evidence may replace conventional TCs within the platform.

Textile Exchange certificate policy

A unified Textile Exchange policy for Scope and Transaction Certificates becomes effective on 1 October 2026 and mandatory from 1 April 2027.

Materials Matter Standard

Textile Exchange’s Materials Matter Standard becomes effective on 31 December 2026 and mandatory for the relevant scope from 31 December 2027, with a longer transition for claims and labels.

European anti-greenwashing rules

Directive (EU) 2024/825 applies from 27 September 2026.

A professional brand should therefore record:

• standard owner;
• standard version;
• certificate validity;
• claim-policy version;
• logo-approval version;
• date of production;
• date of shipment;
• date of public communication.

Certification is not a static logo library.

It is a controlled and evolving compliance system.

---

22. How to Verify a Transaction Certificate

A professional buyer should never validate a TC only by looking at the logo.

Step 1 — Identify the standard

Confirm whether the transaction is GOTS, GRS, RCS, OCS or another eligible system.

Step 2 — Identify the Certification Body

Verify that the issuer is authorised for the standard, country and relevant scope.

Step 3 — Check the seller’s Scope Certificate

Confirm that:

• it was valid on the relevant date;
• the seller’s name and address match;
• the product category is covered;
• the process and facility are covered.

Step 4 — Authenticate the TC

Use the official standard owner’s database or transaction-authentication system where available.

Step 5 — Match the commercial parties

The seller, buyer and consignee should correspond to the real transaction structure.

Step 6 — Match the goods

Compare:

• article;
• material;
• composition;
• colour;
• lot;
• product category;
• certified claim.

Step 7 — Match the quantities

Compare the TC with:

• invoice;
• packing list;
• transport document;
• goods-received record.

Step 8 — Check the dates

The shipment, invoice, certification and issue dates should form a credible sequence.

Step 9 — Check the claim level

Determine whether the evidence supports:

• material claim;
• fabric-lot claim;
• transaction claim;
• final garment claim;
• logo use.

Step 10 — Archive the evidence

Connect the TC to:

• season;
• collection;
• style;
• SKU;
• fabric article;
• colour;
• supplier;
• invoice;
• shipment;
• public claim;
• claim approval.

A disconnected PDF is not a compliance system.

---

23. Transaction Certificate Red Flags

Brands should investigate further when:

• only the supplier’s Scope Certificate is provided;
• the TC number cannot be authenticated;
• the Certification Body is unclear;
• seller details differ from the invoice;
• the supplier’s certificate was expired at shipment;
• the product category is outside the certified scope;
• quantities do not match;
• the TC refers to a different buyer;
• the colour, article or material is inconsistent;
• an altered or incomplete PDF is supplied;
• the supplier refuses to identify the issuer;
• a generic letter is offered instead of transaction evidence;
• a final garment claim is proposed without downstream Chain of Custody;
• logo use is promised without artwork approval;
• the supplier promises certification for any quantity;
• the certification requirement was never included in the order.

One inconsistency does not automatically prove fraud.

It does mean that the claim should be paused until clarified.

24. Certification Must Be Written Into the Order

A Transaction Certificate should not be treated as a courtesy document requested after delivery.

Before confirming the order, the parties should define:

• intended certification;
• exact material and article;
• intended claim;
• target market;
• required Chain of Custody;
• certified seller and buyer structure;
• processing partners;
• technical MOQ;
• permitted colour split;
• segregation requirements;
• document type;
• TC or eTransaction requirement;
• Certification Body costs;
• estimated issuance timing;
• responsibility for claim and logo approval;
• consequences if the route changes.

Suggested certification condition

Certification and Transaction Certificate availability must be confirmed in writing before order acceptance. No certified-product, logo or final-garment claim is authorised unless the applicable article, lot, technical MOQ, Chain of Custody, transaction documentation and claim approval have been completed.

This wording is an educational starting point, not a substitute for legal review or the applicable certification contract.

---

25. Can a Transaction Certificate Be Requested After Delivery?

Sometimes a Certification Body may issue a TC after shipment, provided that:

• the seller was correctly certified;
• the shipment occurred during the relevant certification validity;
• incoming material evidence exists;
• the goods were processed under the certified system;
• required records were maintained;
• application deadlines and certification procedures are respected.

But this must never be assumed.

If certified transaction evidence is a commercial requirement, it should be agreed before:

• material purchase;
• production;
• subcontracting;
• shipment;
• public communication.

A late request cannot reconstruct records, segregation or Chain of Custody that never existed.

26. Why a TC Is Important for Brand Reputation

A Transaction Certificate can help a brand demonstrate that its claims are based on a specific, controlled transaction rather than a generic supplier statement.

It can support:

• buyer due diligence;
• retailer onboarding;
• wholesale compliance;
• material-claim substantiation;
• certification audits;
• traceability systems;
• product-data records;
• investor or ESG review;
• complaint management;
• defence against greenwashing accusations.

However, a TC should sit inside a wider evidence package.

ARNIA’s per-lot traceability framework can include:

• article code;
• description;
• colour or print;
• client SKU;
• lot number;
• fibre composition;
• countries and facilities involved in production;
• process information;
• chemical-compliance data;
• admissible claims;
• logistics;
• deviations or notes.

This is important because certification does not eliminate the need for product, chemical, legal and social due diligence.

---

27. Certification Does Not Replace Daily Due Diligence

A certificate confirms compliance within the rules and assessment methods of a defined standard.

It does not remove the need for daily supplier management.

A responsible textile supply chain should also monitor:

• labour-law compliance;
• health and safety;
• working conditions;
• subcontracting;
• quality;
• documentation;
• chemical conformity;
• delivery risk;
• corrective actions;
• consistency between what is ordered, produced and declared.

This is the reason ARNIA combines certification pathways with:

• Code of Ethics;
• Values Charter;
• supplier selection;
• supply-chain due diligence;
• daily production monitoring;
• quality oversight;
• project-specific traceability;
• responsible claims.

A third-party audit is important.

Daily coherence is equally important.

28. ARNIA’s Process for Certification-Sensitive Projects

At ARNIA TEXTILE FASHION, certification is treated as a project condition from the beginning.

Step 1 — Define the intended claim

The brand must clarify whether it wants to communicate:

• certified fabric;
• certified final garment;
• organic content;
• recycled content;
• FSC-based fibre;
• ECOVERO™ fibre;
• harmful-substance testing;
• traceability;
• social impact;
• Made in Italy production.

Step 2 — Identify the applicable standard

The correct system is selected according to:

• fibre;
• product;
• process;
• market;
• claim;
• quantity.

Step 3 — Check technical MOQ

ARNIA verifies whether the production route can support:

• certified input;
• segregation;
• dedicated processing;
• certified partners;
• documentation;
• TC or alternative evidence.

Step 4 — Map the Chain of Custody

The route may include:

• yarn supplier;
• weaving or knitting;
• dyeing;
• printing;
• finishing;
• converter;
• garment maker;
• brand.

Step 5 — Confirm documentation before order

The order should state what documentation is expected and under which conditions.

Step 6 — Monitor production and quantities

Article, colour, lot, input and output quantities must remain connected.

Step 7 — Request the TC where applicable

A TC or approved digital transaction record is requested only for eligible transactions and routes.

Step 8 — Review the final claim

The brand should not publish a certified-product claim until the evidence and applicable claim rules have been checked.

ARNIA’s public certification references are available through its Sustainable Textiles, Sustainability and Transparency pages. Applicability is always confirmed article by article and lot by lot.

29. A Practical Transaction Certificate Checklist for Fashion Brands

Before using a certification claim, confirm all of the following:

A “No” does not always mean the product is irresponsible.

It means the brand should not yet make the broader certified claim.

Final Takeaway

A Transaction Certificate is powerful because it is specific.

It connects a defined certification standard to a defined transaction.

But it does not certify everything.

A Scope Certificate proves organisational capability.
A Transaction Certificate proves a specific certified transaction.
Chain of Custody protects continuity.
MOQ makes the route technically possible.
Claim approval defines what the brand is allowed to say.
Due diligence verifies that the documents correspond to production reality.

For fashion brands, the safest principle is:

Never build a broad sustainability claim on narrow evidence.

Define the claim first.
Select the right standard.
Map the Chain of Custody.
Confirm the technical MOQ.
Write the certification requirement into the order.
Authenticate the documents.
Communicate only what can be proven.

At ARNIA TEXTILE FASHION, certification is not treated as a logo to add after production. It is part of a controlled sourcing and product-development process designed to protect product integrity, people, clients and brand reputation.

Submit your project through the ARNIA Textile Project Brief to evaluate the material, article, quantity, certification pathway and documentation required for your collection.

FAQ – Transaction Certificates in Fashion: MOQ, Chain of Custody and Anti-Greenwashing Rules

What is a Transaction Certificate in fashion?

A Transaction Certificate is transaction-specific evidence issued or validated by an approved Certification Body for defined certified goods. It usually identifies the standard, seller, buyer, products, quantities, shipment references and certified claim.

What is the difference between a Scope Certificate and a Transaction Certificate?

A Scope Certificate confirms that an organisation is certified for defined locations, activities, processes and product categories. A Transaction Certificate confirms that a specific commercial transaction involving defined goods is covered by the certification system.

Does a Transaction Certificate certify the final garment?

Not automatically. A TC may cover a fabric or material transaction. The final garment claim depends on the complete Chain of Custody, downstream production stages, brand status, labelling requirements and applicable standard.

Is a supplier’s Scope Certificate enough to prove that my fabric is certified?

No. A certified supplier may sell both certified and non-certified goods. The buyer should verify the exact article, lot, transaction and documentation.

Is there a universal GOTS MOQ of 1,000 metres?

No universal production MOQ applies identically to every GOTS project. Around 1,000 metres is ARNIA’s indicative technical planning reference for certain GOTS production routes. Actual feasibility depends on material, process, colour, machinery, certified partners, segregation and documentation.

Is there a universal GRS MOQ of 300 metres?

No. Around 300 metres is an ARNIA planning reference for some yarn-dyed woven jacquard routes. Printed or piece-dyed GRS routes may require around 500 metres. These are operational references, not universal GRS rules.

Why are small lots difficult to certify?

Small lots may not support material segregation, machine setup, minimum yarn or dyeing quantities, certified subcontractors, volume reconciliation and Certification Body administration. The cost and process may also be disproportionate to the quantity.

Can a prototype receive a Transaction Certificate?

Usually not through ARNIA’s normal certified production routes. A prototype may use a documented or certified input, but sample quantities normally cannot support a complete TC pathway or final certified-garment claim.

Can a TC be requested after delivery?

It may be possible under some standards and Certification Body procedures if the complete certified route and records already existed. It should never be assumed. TC requirements should be agreed before production and shipment.

How can a brand verify a Textile Exchange TC?

Textile Exchange provides an official transaction-authentication system for TCs issued after 1 October 2022. The brand should also match seller, buyer, product, quantities, dates and shipment documents.

Does FSC use Transaction Certificates?

FSC generally uses Chain of Custody certification and FSC claims on sales and delivery documents rather than the conventional GOTS or Textile Exchange TC model. The exact FSC claim and trademark route must be confirmed.

Is OEKO-TEX® STANDARD 100 equivalent to GOTS?

No. OEKO-TEX® STANDARD 100 focuses on harmful-substance testing. GOTS covers organic fibres together with processing, chemical, environmental, social and Chain of Custody requirements.

Is GRS the same as RCS?

No. Both verify recycled material and Chain of Custody, but GRS includes additional social, environmental and chemical-processing requirements.

Does OCS prove that a garment was produced under responsible working conditions?

No. OCS verifies organic-material content and Chain of Custody. It does not address broader chemical, social or environmental processing conditions beyond organic-content integrity.

Does Better Cotton mass balance mean my exact garment contains physical Better Cotton?

No. Under mass balance, equivalent volumes are accounted for, but the exact cotton in the individual product may be conventional. Physical BCI Cotton requires a physical Chain of Custody model.

Can a brand use a certification logo after receiving a TC?

Not automatically. Logo and label use normally require compliance with the standard owner’s claims policy, an eligible final product, complete Chain of Custody and approval of the artwork or claim.

What should be included in a purchase order for certified textiles?

The order should define the standard, article, quantity, intended claim, Chain of Custody requirements, expected TC or eTransaction, applicable costs, documentation timing and responsibility for logo or claim approval.

Can a fabric be certified while the garment is not?

Yes. A specific fabric lot may be certified even when the downstream garment-making or brand route does not support a certified final-garment claim.

What should an emerging brand say when final certification is not feasible?

The brand can communicate specific and documented facts, such as responsible material selection, use of a defined certified fabric lot or traceability-aware sourcing. It should avoid describing the final garment or whole collection as certified unless the complete pathway supports that claim.

How does ARNIA confirm certification availability?

ARNIA evaluates certification applicability project by project, article by article and lot by lot. Material, process, quantity, certified partners, Chain of Custody, documentation and intended claim must all be technically reviewed before confirmation.
