How to

1. Look for an identified fiber such as recycled polyester or recycled nylon. Check whether the claim refers to the entire garment or only a particular fabric or component. The US FTC advises specific, substantiated claims instead of vague environmental promises.
2. Read fiber composition and recycled fraction separately. An item labeled ‘80% polyester’ is not necessarily ‘80% recycled polyester’. If a listing says ‘30% recycled content’, check whether it means the whole product or one part.
3. Understand the standards. RCS verifies recycled content and its chain of custody. GRS adds requirements concerning social, environmental and chemical aspects of processing. Textile Exchange describes GRS as more stringent than RCS.
4. Distinguish GRS thresholds. Textile Exchange says at least 20% recycled input is needed for business-to-business certification, but consumer-facing GRS product labeling requires at least 50%. These thresholds are not the exact recycled percentage of the product you are considering.
5. Look for the standard name, certifying body, product scope and verification route. A certified upstream supplier does not automatically establish certification of every finished item. Ask the retailer for evidence specific to the item if the claim is unclear.
6. Compare care instructions, comfort, durability and intended use as well. A materials traceability standard does not prove every performance or end-of-life claim. As of October 2026, Textile Exchange plans to begin transitioning to Materials Matter on December 31, 2026, so review current requirements.

One more tip

Ask what material is recycled and what is certified. A GRS or RCS logo does not automatically prove a garment is non-toxic, impact-free or recyclable after use.
