Recycled Yarn and Certifications for Labels: an Honest Guide
Short answer: Recycled polyester (rPET) yarn can replace virgin yarn in woven labels for brands with a sustainability story. The certificates mean different things: GRS and RCS trace recycled content through the supply chain, while OEKO-TEX Standard 100 tests for harmful substances — it says nothing about recycled origin. Always confirm a certificate's scope, holder and validity before printing claims.
What recycled yarn is - and is not
rPET yarn starts as recycled PET (typically bottles), re-extruded into polyester filament and woven exactly like virgin yarn. For labels, modern rPET performs close to virgin in weave quality and color range, with final feel and shade confirmed on a sample. One labeling nuance buyers miss: in fiber composition terms, recycled polyester is still polyester — the "recycled" part is a marketing and certification claim, not a different fiber name, and green-claim rules in the EU are tightening around exactly this kind of wording.
The certificates, decoded
| Certificate | What it actually certifies | What it does not |
|---|---|---|
| GRS (Global Recycled Standard) | Recycled content traced through each supply-chain step, plus social/chemical criteria | Does not test the final product for harmful substances |
| RCS (Recycled Claim Standard) | Recycled content chain of custody, lighter than GRS | No social or chemical requirements |
| OEKO-TEX Standard 100 | Product tested against a harmful-substances list | Says nothing about recycled origin |
The practical point: "recycled" claims lean on GRS/RCS paperwork; "safe for skin contact" claims lean on OEKO-TEX-type testing. They answer different questions and one does not imply the other.

- Scope — the certificate must cover the actual material and processing step you are buying, not a different product line.
- Holder — check who the certificate is issued to; a mill's certificate does not automatically extend downstream.
- Validity — certificates expire; check the dates and the certificate number against the issuer's database.
- Our stance — recycled polyester yarn is available on request at SAIM Label, and we say plainly: confirm certificate scope and validity before final compliance use, especially if the claim goes on the label or hang tag itself.
FAQ
Is recycled yarn lower quality?
For labels, modern rPET yarn weaves and wears close to virgin polyester. Approve color and hand feel on a physical sample, as with any yarn change.
Does OEKO-TEX mean the label is recycled?
No. OEKO-TEX Standard 100 tests for harmful substances; recycled-content claims are what GRS and RCS cover. They are different certificates for different claims.
Can the recycled claim go on the hang tag?
Only when the paperwork behind it holds up — confirm certificate scope, holder and validity first, and check the destination market's green-claim rules with your importer.
Do recycled-yarn labels cost more?
Usually a premium over virgin yarn; the difference is quoted per order so the brand can decide if the story is worth it.
