OEKO-TEX vs GOTS Certification — What Do They Mean for Your Clothes?
Introduction
You've seen them on clothing labels — OEKO-TEX, GOTS — and you've probably wondered what they actually mean.
Are they meaningful quality indicators or just expensive logos? The honest answer: they're among the most meaningful textile safety credentials in the world.
But they certify different things, and understanding the difference helps you make smarter shopping decisions.
OEKO-TEX vs GOTS — Key Differences
| Feature | OEKO-TEX Standard 100 | GOTS (Global Organic Textile Standard) |
|---|---|---|
| What It Certifies | Product safety — no harmful substances in final garment | Process integrity — organic farming + ethical manufacturing |
| Scope | Fabric, dyes, elastic, thread, buttons — all components | Raw material farm → spinning → dyeing → stitching |
| Testing | 100+ harmful substances incl. PFAS, formaldehyde, heavy metals | Chemical approvals + labour rights audit |
| Organic Claim Required? | No | Yes — 70%+ organic fibres minimum |
| Labour Standards? | No | Yes — mandatory fair employment standards |
| Renewal | Annual re-testing required | Annual supply chain audit required |
| Verification | Certificate number verifiable at oeko-tex.com | Verifiable at global-standard.org |
Substances Tested Under OEKO-TEX Standard 100
| Category | Examples Tested |
|---|---|
| Pesticide Residues | Insecticides, herbicides from raw material farming |
| Azo Dyes | Dyes that release carcinogenic amines on skin contact |
| Formaldehyde | Common fabric finish — major skin sensitiser |
| Heavy Metals | Lead, cadmium, chromium, arsenic |
| PFAS | Per- and polyfluoroalkyl 'forever chemicals' |
| pH Value | Skin-neutral range verified (4.5–7.5) |
| Allergenic Dyes | Dyes known to cause contact allergies |
| Flame Retardants | Halogenated compounds used in synthetic treatments |
Why Most Indian Brands Have Neither Certification
Both certifications require ongoing investment: testing fees, supply chain audits, and facility compliance upgrades.
For fast-fashion brands competing on price, these costs are often incompatible with their business model.
The result: the vast majority of innerwear sold in India carries no independent safety certification.
For intimate wear worn against sensitive skin for 16+ hours daily, trusting unverified claims is a risk worth rethinking.
How to Verify a Brand's Certification
OEKO-TEX:
- Go to oeko-tex.com
- Click “Check Certificate”
- Enter the certificate number shown on the product or brand website
GOTS:
- Visit global-standard.org
- Search by company name in the Public Database
If a brand claims certification but can't provide a verifiable certificate number, the claim is unverified.
Legitimate certifications always have a certificate number and an expiry date.
