OEKO-TEX vs GOTS vs GRS — what each certification actually proves

Why this question matters more than you think

If you're a buyer at an international retailer, you'll see all three of these certifications quoted across nearly every Indian home textile manufacturer's homepage. Most buyers assume they're broadly interchangeable — that "certified" means "sustainable" and the differences are technical fine print.

That assumption causes problems. The three certifications test fundamentally different things. Confusing them at the PO stage leads to compliance gaps at retail audit, retailer claims you can't back up, and (rarely but expensively) consumer-litigation risk under green-marketing rules in the EU and California.

So here's the plain-English version: what each one tests, what it does not guarantee, and when buyers should ask for which.

OEKO-TEX Standard 100 — what it tests

OEKO-TEX Standard 100 is a finished-product chemical-safety test. It says: this textile, in its final form, has been laboratory-tested against a list of restricted substances and falls within safe limits.

What it tests:

• Hundreds of regulated chemicals: AZO dyes, formaldehyde, heavy metals, pesticides, phthalates, allergenic disperse dyes, banned flame retardants, biocides and more.
• Finished product (the actual fabric or made-up item), not the raw fibre or process.
• Different "product classes" with stricter limits for products that contact skin (Class I-II) than for decorative or outerwear (Class III-IV).

What OEKO-TEX does not prove:

• Anything about how the cotton was grown (conventional vs organic).
• Anything about working conditions or worker pay.
• Anything about water or energy use in production.
• Whether recycled-content claims are real.

OEKO-TEX is the baseline for almost any export-grade home textile. International retailers expect it as table stakes. If a manufacturer can't show a current OEKO-TEX certificate at the facility-or-product level, that's a stop-the-conversation flag.

GOTS — what organic actually means

GOTS (Global Organic Textile Standard) is a chain-of-custody system for organic cotton. It traces certified-organic fibre from farm to finished product, and certifies every link in the chain.

What GOTS covers:

• The fibre must come from a certified-organic farm (no synthetic pesticides or fertilizers; following organic-agriculture standards).
• Every processor in the chain (ginning, spinning, weaving, dyeing, printing, making-up) must hold GOTS scope certification.
• Dyes and process chemicals must meet stringent GOTS requirements (more restrictive than OEKO-TEX in some categories).
• The facility must meet GOTS social-compliance criteria (similar to but not identical to SA 8000 / Sedex).
• The transaction certificate (TC) issued per shipment proves the fibre flow.

What GOTS does not guarantee:

• That the product is recycled or low-carbon — organic cotton uses a lot of water and land.
• That labour conditions match Sedex SMETA-level audit. (GOTS social criteria overlap with SMETA but aren't identical.)

When to ask for GOTS: when your retail SKU will carry an organic claim — "GOTS organic cotton bath mat", "100% organic cotton bedding", etc. If you're not making organic claims at retail, you don't need GOTS — OEKO-TEX is sufficient.

GRS — the recycled-content standard

GRS (Global Recycled Standard) is the analog of GOTS, but for recycled materials — recycled cotton, recycled polyester, recycled wool, etc.

What GRS covers:

• The recycled-content fibre must come from a certified-recycled source (post-consumer or pre-consumer waste).
• Every processor must hold GRS scope certification.
• Dye and chemical inputs are restricted (similar restrictions to GOTS, with adjustments for synthetic fibres).
• Per-shipment transaction certificates document the recycled fibre flow.
• Recycled content can be 20%+ (RCS) or 50%+ (GRS proper). Most international retailer programmes require GRS-proper.

Variants and adjacent standards:

• RCS (Recycled Claim Standard) — lighter version that just verifies recycled content (20%+) without the chemical and social criteria of GRS.
• OCS (Organic Content Standard) — lighter version of GOTS that verifies organic content without GOTS process restrictions.

When to ask for GRS: if your SKU will be sold as "recycled cotton", "recycled polyester" or "made from post-consumer waste". For retail-grade claims, GRS is the safer choice over RCS because it covers process and social criteria too.

Side-by-side comparison

Which to ask for, when

Practical heuristic for buyers:

• All shipments: require OEKO-TEX Standard 100 certificate covering the product class and validity period of the shipment.
• Organic SKUs: require GOTS scope certificate and a GOTS Transaction Certificate (TC) issued for the specific shipment.
• Recycled SKUs: require GRS scope certificate and a GRS Transaction Certificate (TC) issued for the specific shipment.
• BCI-claim SKUs: require BCI mass-balance documentation. (BCI isn't physical traceability — it's a credits system. Different conversation.)
• Mixed SKUs (e.g., 50% organic + 50% conventional): require OCS Blended (Organic Content Standard - Blended) certification. GOTS won't apply because GOTS needs 70%+ certified organic.

Documentation that should accompany every shipment

This is what a serious manufacturer should provide as part of the shipment documentation pack, without you having to chase it:

• Current scope certificates for OEKO-TEX, GOTS and/or GRS (whichever apply to the SKUs in the container).
• Shipment-specific Transaction Certificates (TCs) for GOTS and GRS goods. (OEKO-TEX doesn't issue TCs; the product-level certificate is sufficient.)
• Lab test reports backing the OEKO-TEX class for each SKU.
• Sedex SMETA 4-pillar audit report covering the producing facility.
• Care label and country-of-origin documentation.
• Test reports for any retailer-specific compliance (CPSIA flammability, REACH SVHC, California Prop 65, etc.).

If a manufacturer can't produce these on request, treat it as a flag — either their compliance posture is weak, or they're going to scramble at the last minute and miss things.

Red flags and common mistakes

"We're OEKO-TEX certified" without showing the certificate

Always ask for the scan. The certificate names the certified product (or class), the certifying institute, the certificate number and the validity period (usually 12 months from issue). Verify the certificate at OEKO-TEX's label check tool. Genuine certificates show up; fake ones don't.

Mixing OEKO-TEX and GOTS as if they're equivalent

"This product is OEKO-TEX certified, so it's organic." No. OEKO-TEX says nothing about how the cotton was grown. Don't let manufacturer marketing copy bridge the two.

GOTS certificate but no Transaction Certificate

A scope certificate proves the manufacturer is permitted to handle GOTS goods. A Transaction Certificate proves your specific shipment contains GOTS-compliant material. Both are needed for retail claims.

"Recycled cotton" without GRS

Recycled fibre is much harder to verify than virgin fibre. Without GRS chain-of-custody, "recycled" claims are unverifiable, and increasingly subject to greenwashing-rule challenges.

Expired certificates

All three certifications expire annually. A 2024 OEKO-TEX certificate displayed in 2026 is not valid scope. Insist on current-year documents at PO sign-off.

Bottom line

If you remember nothing else: OEKO-TEX is about chemicals in the finished product. GOTS is about organic-cotton chain-of-custody. GRS is about recycled-content chain-of-custody. They're complementary, not interchangeable. Most retail programmes need OEKO-TEX always, plus GOTS or GRS depending on the claim being made on the retail SKU.

Abhi Home holds all three (and several others) at facility scope, with annual audit cycles and per-shipment TCs as standard. If you're evaluating Indian home textile manufacturers, expect this combination as a minimum competence bar.
