Definition
GRS certified means a product has been audited against the Global Recycled Standard, which verifies how much recycled material is actually in it and tracks that material through every factory in the chain. The standard also sets rules on chemicals, wastewater, and working conditions. It is the reason a supplier can say "made from recycled bottles" and prove it with paperwork rather than a photo of a bottle.
Definition
The Global Recycled Standard is owned by Textile Exchange, a non-profit, and audited by accredited certification bodies such as Control Union and Intertek. It applies to any product with at least 20 percent recycled material, and it follows that material from the recycler through spinning, weaving, dyeing, and assembly. Say you order 3,000 rPET fleece jackets described as 100 percent recycled polyester. GRS certification means an auditor has checked the recycler's input records, matched them against what the mill received, and issued a transaction certificate covering your specific shipment. Without that certificate, the recycled claim is untested.
How GRS certified works
There are two thresholds. A product needs 20 percent or more recycled content to be GRS certified at all. It needs 50 percent or more before the GRS logo can appear on the product itself, on hangtags, or in consumer-facing marketing. Both pre-consumer waste, meaning factory offcuts and production scrap, and post-consumer waste, meaning used bottles and garments, count toward the total. The standard requires the exact percentage to be declared, so a 65 percent recycled polyester bag and a 100 percent one are both certified but tell different stories.
The chain of custody is where GRS gets its teeth. Every operator that takes ownership of the material, from the recycler to the final decorator if branding happens under scope, needs its own scope certificate. Each sale between them generates a transaction certificate. That paper trail is what stops recycled and virgin polyester being quietly swapped at the mill, which is the most common failure point in recycled supply chains and the reason recycled content claims were unreliable before the standard existed.
Beyond content, GRS carries requirements that a content-only standard does not. Restricted chemicals cover the dyes and auxiliaries used in processing. Facilities must manage wastewater and monitor discharge. Social criteria are based on the core ILO conventions, so audits also look at wages, hours, and forced or child labor. This is the difference between GRS and its sister standard, the Recycled Claim Standard, which verifies content and traceability only and stays silent on chemistry and labor.
GRS certified in branded merch
- Recycled polyester apparel and outerwear: Fleece, softshells, and performance tees made from rPET are the biggest category. GRS is what lets you put a recycled percentage on a spec sheet and defend it if procurement or a journalist asks for the source.
- Bags and backpacks: Recycled polyester and recycled nylon dominate the bag category. A GRS certified backpack lets you state the exact recycled content of the main body fabric, which is often the only sustainability claim a bag can make honestly.
- Corporate reporting and tenders: Buyers with CSRD or ESG reporting duties need auditable evidence, not supplier statements. GRS transaction certificates give finance and sustainability teams something they can file.
GRS certified means a product's recycled content has been independently verified and traced through the supply chain, alongside chemical, environmental, and social requirements.
5 tips to elevate your GRS certified strategy
| Tip | Steps |
|---|---|
| Ask which threshold applies | Confirm whether the item clears 50 percent, since below that you cannot use the GRS logo in your marketing. |
| Get a transaction certificate | A scope certificate only proves a factory is certified. Only a transaction certificate ties your specific order to certified material. |
| Check the certified component | GRS often covers the main fabric, not zips, linings, or trims. Ask what is inside the certified scope before you write copy about it. |
| Do not confuse GRS with RCS | RCS verifies recycled content and traceability only. If you want chemistry and labor covered, specify GRS by name. |
| State the percentage | Publishing the exact recycled percentage is more credible than a vague recycled claim, and GRS requires you to know it anyway. |

Frequently Asked Questions
How much recycled content does GRS require?
A minimum of 20 percent recycled content is needed for a product to be GRS certified. At least 50 percent is needed before the GRS logo can be used on the product or in consumer-facing marketing.
What is the difference between GRS and RCS?
Both verify recycled content and chain of custody. GRS adds requirements on restricted chemicals, wastewater, environmental management, and social criteria based on ILO conventions. RCS covers content and traceability only.
Does GRS cover the whole product or just the fabric?
It covers whatever is inside the certified scope, which is usually the main fabric. Zips, trims, linings, and hardware are often excluded, so ask the supplier which components the certificate applies to.
Can printing or embroidery break a GRS claim?
The certified claim applies to the material itself, so decoration does not erase the recycled content. If you want the finished branded item covered under scope, the decorator has to be GRS certified too.
How do I verify a GRS certificate?
Ask for the scope certificate and check it against the Textile Exchange certified supplier list. Then request a transaction certificate for your specific order, since that is the only document that connects certified material to your units.
