	Global Organic Textile Standard Global · Tier 2 Trusted	? 'Natural' (NOT a certification) Worldwide · Tier 4 Marketing	$OEKO-TEX Standard 100 logo$ OEKO-TEX Standard 100 Global · Tier 3 Specialty	JAS Organic Japan · Tier 1 Gold
What it means	The strictest, most widely-recognised standard for organic textiles. Covers the full supply chain from organic fibre to finished garment, with environmental AND social criteria.	The word 'natural' on packaging is a marketing term, not a certification. In most jurisdictions there's no legal definition, no standard, and no inspection. A product labelled 'natural' can contain synthetic ingredients, pesticides, GMOs, and artificial flavours.	Tests finished textiles for harmful substances. Important: OEKO-TEX 100 is NOT an organic certification — it certifies that the finished item is free of certain chemicals, regardless of how the fibre was grown.	Japan's national organic standard under the Japanese Agricultural Standard system. The mark must appear on any food sold as 'organic' (有機 or オーガニック) in Japan.
Scope	Textiles	Several categories	Textiles	Food

Guarantees	≥70% certified-organic natural fibre (the 'organic' grade requires ≥95%). Restricted dyes, no chlorine bleach, no formaldehyde, no banned heavy metals. Wastewater treatment requirements. Social standards based on ILO core conventions (no child labour, no forced labour, fair wages, safe workplace). Annual on-site inspection by IOAS-accredited certifier.	Nothing. It is not a certification and there is no body verifying anything.	Finished textile tested against the OEKO-TEX harmful-substance limit list. Limits on heavy metals, formaldehyde, pesticide residue, banned amines, allergenic dyes.	≥95% organic ingredients. No synthetic pesticides, no synthetic fertilizers, no GMOs. Annual inspection by a MAFF-registered certifier.
Does NOT	Doesn't cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.	Doesn't mean organic. Doesn't mean pesticide-free. Doesn't mean GMO-free. Doesn't mean ethically produced. Some markets (e.g. the US FDA on food, EU on cosmetics) place very limited restrictions on the word, but enforcement is weak.	Does NOT mean organic. Does NOT cover farming, dyeing chemistry beyond the limit list, or social/labour standards. A 100% conventional cotton t-shirt can be OEKO-TEX 100 certified.	Mutual recognition with the US, EU, and Canada applies to specific product categories — check each agreement before importing.
