Certifications Decoded: GOTS, GOLS, OEKO-TEX & What Actually Matters

The labels on organic home goods are where most buyers get lost. Here's what each certification actually verifies — and the marketing words that mean nothing.

The ones that matter

GOTS (Global Organic Textile Standard) is the floor for cotton and wool. It certifies the entire supply chain — fiber, spinning, dyeing, finishing, sewing — and bans a long list of chemical inputs. The trap: a brand can use GOTS-certified cotton and still produce a non-GOTS finished sheet. Look for certification of the product, not the fiber.

GOLS (Global Organic Latex Standard) is the equivalent for latex — it verifies organic content and clean processing. “Natural latex” without GOLS can be cut with synthetic.

OEKO-TEX Standard 100 verifies a finished textile is free of harmful substances but says nothing about how it was farmed. It's the right credential for linen (paired with European Flax, which verifies origin) and a useful add-on for cotton.

Fair Trade Certified covers labor and wages, not organics. MADE SAFE screens against a database of known hazardous chemicals. GreenGuard Gold sets low chemical-emission limits — the credential to demand on any foam.

The words that mean nothing

• “Made with organic cotton” — can be as little as 10% organic, with no GOTS on the finished product.
• “Bamboo” without OEKO-TEX — almost always rayon, dissolved out of the plant with a harsh solvent.
• “Eco-friendly,” “sustainable,” “hypoallergenic” — with no named third-party certification, these are marketing, not evidence.

For cotton, GOTS is the floor; for linen, OEKO-TEX plus European Flax is the equivalent. Anything labeled only “organic” with no certifying body behind it is a word, not a guarantee. More on how we apply all this: The iOrganic Standard.
