GOTS vs GRS Certification: What Buyers Should Verify
If you source apparel or home textiles on behalf of a brand, retailer, or buying house, you've seen "GOTS certified" and "GRS certified" on supplier profiles, factory presentations, and product tags. They're often mentioned in the same breath, as if they were two versions of the same thing. They aren't! They certify different claims, and a certificate on a supplier's website doesn't automatically mean the product you're about to order carries that claim.
This guide explains what each standard actually covers, where buyers commonly get caught out, and what to verify before you rely on a GOTS or GRS claim in a purchase order, a compliance file, or a customer-facing label.
What GOTS Certifies
The Global Organic Textile Standard (GOTS) is about organic fibre, tracked through the manufacturing chain. It covers:
Organic fibre content — the product must contain a minimum share of certified organic fibre to carry a GOTS label. There are two label grades: "organic" (at least 95% certified organic fibre) and "made with organic" (at least 70%)
Processing criteria — restrictions on chemical inputs, dyes, and finishing agents, plus requirements around wastewater treatment
Social criteria — baseline requirements for working conditions, drawn from international labour standards
Labelling and traceability — rules on how the claim can be presented, and how certified material is tracked through each stage
In short: GOTS answers the question, "Was this made from organic fibre, and processed responsibly?"
What GRS Certifies
The Global Recycled Standard (GRS), managed by Textile Exchange, is about recycled content. It covers:
Recycled material content — verifying that the recycled input in the final product is what the supplier says it is, with minimum recycled-content thresholds for certification and for use of the label (check the current version of the standard for exact figures, as these can be updated)
Chain of custody — tracking recycled material from the point of input through to the finished product
Environmental and chemical requirements — restrictions on processing, including chemical use
Social requirements — baseline expectations for workers' rights and conditions at certified facilities
In short: GRS answers the question, "Is this product actually made with the recycled content claimed, and was it processed responsibly?"
GOTS vs GRS at a Glance:
Below is the comparative matching of GOTS vs GRS certifications
GOTS | GRS | |
Core claim | Organic fibre | Recycled content |
Typical materials | Organic cotton, organic linen, organic wool | Recycled polyester, recycled cotton, recycled nylon |
Tracks | Organic status through the supply chain | Recycled input through the supply chain |
Also covers | Chemical, wastewater, and social criteria | Chemical, environmental, and social criteria |
Doesn't tell you | Whether any recycled content is used | Whether any organic fibre is used |
A product can be GOTS-certified, GRS-certified, or both (for example, a garment using a blend of organic and recycled fibres from separately certified supply chains), but one does not imply the other.
Four Common Misunderstandings:
1. "GOTS and GRS mean basically the same thing." They don't. If your brand's claim is "made with organic cotton," a GRS certificate doesn't support it, and if your claim is "made with recycled polyester," a GOTS certificate doesn't either. Match the certificate to the claim.
2. "The fabric is certified, so the garment is certified." Certification applies facility by facility. A certified fabric mill doesn't make the garment factory certified, and a garment can only carry the claim if every stage that handles the certified material in scope is also covered. This is the most common gap in practice.
3. "They sent a certificate, so we're covered." A certificate has a scope, a validity period, and a list of what it applies to. It may be expired, issued to a different legal entity than the one you're buying from, or cover a different product category or process than your order.
4. "Certification replaces a social compliance audit." GOTS and GRS include social criteria, but many retailers and brands still require separate social compliance audits as part of their own supplier approval process. Check what your buyers' codes of conduct actually require, rather than assuming a standards certificate satisfies them.
What to Verify Before You Rely on the Claim
Use this as a working checklist when vetting a supplier:
Check the scope certificate in detail. Confirm the legal entity name and address match the factory you're actually buying from, the certificate is within its validity dates, and the product categories and processing stages listed include what you're ordering.
Verify it against the public database. Both standards maintain public listings of certified facilities. Confirm the certificate number and status there, rather than relying only on a PDF the supplier sent.
Confirm the certification body. The certificate should be issued by a recognised, approved certification body for that standard.
Ask for transaction certificates (TCs) per shipment. A facility's scope certificate says it is able to produce certified goods. A transaction certificate links a specific shipment to certified material. If the claim matters for your order, the TC is the document that supports it.
Map every stage of production. Ask who handles spinning, weaving or knitting, dyeing, printing, embroidery, washing, and cut-and-sew. Any outsourced stage that touches the certified material needs to be covered as well.
Check the label and claim wording. If the product carries a certification label, the licence number and label grade need to be correct, and any marketing language needs to match what the certification actually allows.
Request traceability documentation. For a claim to hold, you should be able to follow the certified material from fibre to fabric to finished product.
Red Flags to Watch For:
A certificate issued to a trading company or a different legal entity than the one producing your goods
Expired certificates, or certificates close to expiry with no sign of renewal
A scope that doesn't list your product category or a key processing step
Reluctance to share certificate numbers or transaction certificates
Phrases like "GOTS quality," "GOTS compliant," or "GRS standard" with no certificate number, which are not the same as certified
A supplier who can only point to a certified fabric supplier, with no certification of their own for the stage you're buying
Why This Matters More Now
Environmental claims on textiles and home furnishings are under increasing regulatory and retailer scrutiny across the UK, EU, US, and Australia, with consumer protection bodies actively focused on unsupported "sustainable," "organic," and "recycled" claims. For a sourcing or buying agent, that means a claim in a purchase order or on a product label is only as strong as the paperwork behind it. Verifying the certificate, scope, and transaction documents up front is far less costly than discovering a gap after goods have shipped.
The Bottom Line
GOTS and GRS are valuable, credible standards, but they certify different things, apply facility by facility, and only support a claim when the scope, validity, and transaction documents all line up with the order in front of you. Treat the certificate as the starting point for verification rather than the end of it, and match each certification to the specific claim your client or brand intends to make.
