How recycled-content certification and claims work
Recycled content is a claim about where material came from, and it cannot be seen, felt or tested in a finished garment. That is why the schemes covering it are built around chain-of-custody documentation rather than product inspection, and why the documentation is the substance of the claim rather than paperwork attached to it.

Recycled polyester behaves like polyester. There is no laboratory test on a finished garment that distinguishes a recycled input from a virgin one in the way a fibre-composition test distinguishes cotton from polyester. Everything a buyer can say about recycled content therefore rests on the evidence trail from the recycler forward, and the schemes in this area exist to make that trail auditable.
That single fact explains why a recycled-content programme is documentation-heavy in a way an ordinary fabric programme is not, and why a supplier saying a fabric is recycled is the beginning of a conversation rather than the end of one.
Two standards, doing different amounts of work
Textile Exchange owns two standards often named in apparel enquiries, and the difference between them is not a detail.
| Recycled Claim Standard | Global Recycled Standard | |
|---|---|---|
| Verifies recycled content | Yes | Yes |
| Chain of custody | Yes | Yes |
| Additional processing requirements | No | Yes, including social, environmental and chemical criteria in processing |
| Typical use | Where the requirement is to substantiate the recycled content itself | Where the requirement extends to how the material was processed |
Reducing the Global Recycled Standard to a certificate proving recycled polyester therefore understates it, and the understatement has commercial consequences: a buyer who specifies it expecting only a content check is asking suppliers for more than they realise, and a buyer who specifies a content standard while intending to make a broader claim has bought less evidence than they need.
Which of the two a programme needs follows from the claim. If the claim is about how much recycled material is in the product, a content standard addresses it. If the claim reaches into how the material was made, the broader standard is the one that carries that evidence.
The Materials Matter transition
Textile Exchange is consolidating its standards into a single scheme, and anyone specifying recycled content in 2026 and 2027 needs the dates rather than a general impression that something is changing.
| Date | What happens |
|---|---|
| 1 April 2026 | The Materials Matter transition policy is published |
| 31 December 2026 | The Materials Matter Standard becomes effective |
| During 2027 | An optional implementation year. Eligible organisations at the farm, recycling and primary processing level, certified to the existing recycled or animal fibre standards, may choose to be audited to the new standard |
| 31 December 2027 | The Materials Matter Standard becomes mandatory |
| From 2028 | The Materials Matter Standard is required for those audits in order to maintain certification |
| 31 March 2029 | Accreditation bodies do not maintain valid accreditations to the existing recycled and animal fibre standard scopes beyond this date |
The first version of the new standard covers the materials currently covered by the Responsible Animal Fiber framework, including wool, alpaca and mohair, together with recycled materials as currently covered by the two recycled standards.
For a buyer, the practical effect over the next two years is modest but worth planning for. A programme that will still be running in 2028 should ask suppliers where they are in the transition rather than assuming the certificate they hold today will be the certificate they hold then, and a long-term specification is better written around the requirement than around a standard's name.
The current position, the standard documents and the transition policy are published by Textile Exchange.
What a recycled claim needs behind it
Recycled content works the same way as any other chain claim: the material has to be certified, the organisations handling it have to be inside the system, and the specific goods have to be documented as they move. A certificate held by a fabric supplier is evidence about that supplier, not about your delivery.
Two consequences follow for a garment programme. The percentage matters and has to be specified rather than described, because a claim is about a number. And the point at which certification stops in the chain determines what can be said about the finished garment, which is the general principle set out on the certified materials hub.
A worked example
The enquiry as it usually arrives
- "280 gsm brushed fleece, 80% cotton 20% recycled polyester, GRS required"
What still has to be settled
- Which standard is actually required, and whether the recycled content alone is the requirement or the processing criteria are too
- Whether the 20% is the recycled portion of the whole fabric or the polyester component
- What claim the finished product needs to carry, and therefore how far down the chain certification has to reach
- Whether transaction documentation is required for the delivery
- Which market the claim will be made in
- Whether the required content is achievable in the construction and weight specified
That example is constructed, not a real order. It is included because the gap between the two columns is where many recycled-content programmes lose time, and because every item in the right-hand column is answerable in an enquiry rather than after sampling.
Content, and what the material actually is
One clarification saves a recurring argument. Recycled polyester is polyester: it does not perform differently by virtue of being recycled, and its behaviour follows from the fibre and the construction, which is covered in performance polyester knits. Nor does recycled content say anything about harmful-substance testing, which is a separate certification addressed in OEKO-TEX STANDARD 100.
The corollary matters too: a fabric can be genuinely made from recycled input and still not support a certified claim, because the claim depends on the chain and the documentation rather than on the material's history alone.
Questions this raises
What is the difference between the Global Recycled Standard and the Recycled Claim Standard?
Both verify recycled content and both require chain of custody. The Global Recycled Standard goes further by adding requirements on how the material is processed, including social, environmental and chemical criteria. Which one a programme needs follows from whether the claim is only about content or also about processing.
Is a recycled polyester garment automatically GRS certified?
No. Recycled content in the material is not the same as a certified product claim. The claim depends on certified organisations handling the goods and on the documentation that travels with a specific delivery, which is why the evidence trail rather than the material itself is what supports the claim.
Does the Global Recycled Standard disappear at the end of 2026?
No. The Materials Matter Standard becomes effective on 31 December 2026 and mandatory on 31 December 2027, with 2027 as an optional implementation year and accreditations to the existing standard scopes not maintained beyond 31 March 2029. Existing standards remain usable through the transition. Confirm the current position with Textile Exchange for any programme running across those dates.
How is recycled content verified in a finished garment?
Not by testing the garment. Recycled polyester is chemically polyester, so there is no product test that distinguishes it from virgin material the way a composition test distinguishes fibres. Verification is documentary, through certified organisations and the transaction records that follow the goods.
Give the percentage and the claim
A recycled-content requirement is a number plus a claim plus a documentation route. Send all three with the enquiry and the quotation will reflect what is actually achievable.
