	Global Organic Textile Standard Global · Tier 2 Trusted	Korea Organic South Korea · Tier 1 Gold	JAS Organic Japan · Tier 1 Gold	? 'Natural' (NOT a certification) Worldwide · Tier 4 Marketing
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.	South Korea's national organic mark under MAFRA (Ministry of Agriculture, Food and Rural Affairs). Required on any food sold as 유기농 in Korea.	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.	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.

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.	≥95% organic ingredients. No synthetic pesticides, no GMOs. Annual on-site inspection by a MAFRA-accredited certifier.	≥95% organic ingredients. No synthetic pesticides, no synthetic fertilizers, no GMOs. Annual inspection by a MAFF-registered certifier.	Nothing. It is not a certification and there is no body verifying anything.
Does NOT	Doesn't cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.	Cosmetics and textiles are covered under separate Korean schemes, not this mark.	Mutual recognition with the US, EU, and Canada applies to specific product categories — check each agreement before importing.	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.
