GRS Explained: What the Global Recycled Standard Covers and Who Needs It

Buyers and retailers increasingly ask suppliers to prove that recycled materials really are recycled. That's the gap GRS is designed to close.

What GRS actually is

GRS stands for Global Recycled Standard. It's a voluntary certification, owned by Textile Exchange, that verifies recycled content in a product and tracks that material through every stage of production. GRS doesn't just check the final item — it follows the recycled input from the recycler through spinning, weaving, dyeing, manufacturing, and on to the finished good, so each link in the supply chain can be traced.

Who it applies to

GRS applies globally, not to one country or market. It's most relevant if you import or resell products made wholly or partly from recycled materials — recycled polyester fabric, recycled cotton blends, recycled plastic components, and similar inputs. If your product line, or a supplier, markets items as "recycled" or "made from recycled materials," GRS is the certification a buyer is likely to expect as proof.

It applies at every stage a product passes through, not just to the final manufacturer. Spinners, weavers, dye houses, cut-and-sew factories, and traders handling certified material each need their own certification to keep the chain of custody intact. If one link in that chain isn't certified, the recycled claim can't be verified further down the line.

What GRS requires

A GRS-compliant shipment needs several pieces of documentation in place:

Without these, a "recycled" claim on a product label or marketing material isn't backed by verifiable proof, which is the exact gap GRS certification closes for buyers.

Checking before you commit

If you're sourcing from a new supplier and recycled content matters to your buyers, ask for the GRS certificate and transaction certificate before confirming the order, not after goods have shipped. You can find more on what's involved on the [GRS](/regulations/grs) page, and on verifying supplier documentation more broadly on the [supplier compliance](/supplier-compliance) page.
