GRS-Certified Knit Fabrics: What to Expect<\/h1>\n

A GRS label is a shortcut to a sustainable claim, but only if it is real. GRS (the Global Recycled Standard) certifies the recycled content of a product and the chain of custody behind it. Anything that says GRS without a traceable certificate is just a green sticker. Fursone<\/strong> works with GRS and OEKO-TEX certified materials, so here is what the certification should actually give you.<\/p>\n

\"GRS<\/p>\n

What GRS actually certifies<\/h2>\n

GRS verifies three things: that the material contains a minimum recycled content, that every step from yarn to finished fabric has been tracked, and that social and environmental criteria were met along the way. It is a chain-of-custody certification, not just a fibre claim. That is what separates it from a self-declared “eco” label. Textile Exchange<\/a> administers the GRS standard, and the certificate is what you verify.<\/p>\n

Why the percentage matters<\/h2>\n

GRS products carry a recycled-content percentage, and the number matters. A fabric with a 50% recycled content claim is a different product from one with 100%, and each carries a different certificate. If your collection promises a certain recycled share, the certificate must back the number you print. This is the single most misused part of an eco claim.<\/p>\n

How to verify a certificate<\/h2>\n

Ask the supplier for the certificate number and the name of the certifying body, then confirm the scope covers the product you are buying and the facility that made it. Check that the certificate is still valid and that the percentage matches your claim. A supplier that shares a certificate number and a scope you can check is a supplier that actually holds it. We walk through the 50% rule and the checks you should run in the GRS recycled-content rule<\/a>.<\/p>\n

\"GRS<\/p>\n

What it adds to cost and lead time<\/h2>\n

Certified material is a real cost. Recycled yarn and the tracking behind it usually add to the price and can tighten the supply, so a GRS knit often carries a modest premium and a slightly longer lead. That is acceptable when your market demands it, but worth budgeting. At Fursone<\/strong> we offer custom runs from a 300M MOQ with 7-day sampling, so you can test a certified knit before you scale a whole line.<\/p>\n

Pair it with the right certifications<\/h2>\n

GRS covers recycled content but not chemical safety. For a fabric that touches skin, OEKO-TEX Standard 100 is the certification that covers restricted substances. Read OEKO-TEX Standard 100<\/a> to understand the difference. Together, a GRS plus an OEKO-TEX claim is a stronger and more honest position than either alone, and it is the combination we use when we can.<\/p>\n

Order a certified knit<\/h2>\n

If you want a genuinely certified knit, start with our sustainable fabric design<\/a> page and tell us the recycled-content target and the certification you need. We are ISO certified and carry GRS and OEKO-TEX certifications, and we hold a 100M stock that ships in days with no minimum for testing. Our GRS eco-knit athleisure case<\/a> shows how this looks in practice.<\/p>\n

FAQ<\/h2>\n

What does GRS-certified mean for a knit fabric?<\/h3>\n

It certifies a minimum recycled content, a tracked chain of custody from yarn to fabric, and social and environmental criteria. It is a verified chain-of-custody claim, not just a label.<\/p>\n

How do I verify a GRS certificate?<\/h3>\n

Ask for the certificate number and the certifying body, confirm the scope covers the product and facility, and check it is valid. The recycled-content percentage must match the claim you print.<\/p>\n

Is GRS the same as OEKO-TEX?<\/h3>\n

No. GRS covers recycled content and chain of custody; OEKO-TEX Standard 100 covers restricted chemicals that could touch the skin. Many brands pair them.<\/p>\n
