OEKO-TEX® Class I vs GOTS Organic: A Buyer's Guide
Two of the most requested certificates in innerwear are OEKO-TEX® Standard 100 and GOTS. Buyers often treat them as interchangeable "eco" badges. They are not — they answer different questions, and using them wrongly on a label is a compliance risk. Here is the plain-English version.
OEKO-TEX® Standard 100 — is it safe?
OEKO-TEX Standard 100 tests the finished textile for harmful substances. It says nothing about whether the cotton was grown organically — it is a safety certificate, not a sustainability one.
What makes it powerful is the product class:
- Class I is the strictest tier — the limits set for articles for babies and toddlers.
- Classes II–IV apply to products with progressively less direct skin contact.
If your fabric is certified to Class I, you can honestly tell buyers it meets the safety limits set for baby articles — a strong, verifiable trust claim for men's, women's and kids' lines alike.
GOTS — is it organic?
GOTS (Global Organic Textile Standard) certifies that the product is made from certified organic fibres and processed to strict environmental and social criteria across the whole chain. This is the certificate to use when your positioning is organic / sustainable.
Two things buyers miss:
- A Scope Certificate proves the *manufacturer* is certified. Proof that a *specific shipment* is GOTS goods comes from a Transaction Certificate (TC) — ask for it if you're making organic claims at retail.
- GOTS marks are trademarked. Only use the logo and wording while the certificate is valid and covers your product.



Which one does your market need?
- Selling on safety and comfort (most core innerwear)? OEKO-TEX Class I is your headline.
- Selling on organic / eco positioning, especially in the EU? You need GOTS — and the transaction certificates to back it.
- Want both? Many premium lines carry OEKO-TEX Class I as standard and offer a GOTS organic option as an upgrade tier.
Displaying them without legal risk
- Show a certificate only when it is current and covers the exact goods.
- Use the official licensed logos, not redrawn look-alikes.
- Keep certificate numbers handy so buyers can verify (OEKO-TEX via the certificate ID; GOTS via the certifier).
