	OTC OEKO-TEX Organic Cotton Global · Tier 2 Trusted	? 'Natural' (NOT a certification) Worldwide · Tier 4 Marketing	Korea Organic South Korea · Tier 1 Gold	Luomu (Finland) Finland · Tier 2 Trusted
What it means	Launched April 2023 by the OEKO-TEX Association. A separate certificate from Standard 100 that combines the Standard 100 chemical-residue test with verified organic-cotton supply chain — addressing the long-standing confusion that Standard 100 alone is NOT an organic mark.	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.	South Korea's national organic mark under MAFRA (Ministry of Agriculture, Food and Rural Affairs). Required on any food sold as 유기농 in Korea.	Finland's national organic 'Sun Mark' (Aurinkomerkki). Operated by the Finnish Food Authority. In practice most Finnish organic packaging carries both Luomu and the EU Leaf — they certify to the same baseline.

Guarantees	Two grades: 'Organic Cotton' (100% certified-organic cotton) and 'Organic Cotton Blended' (≥70% certified-organic cotton). Full Standard 100 chemical residue test on the finished product. Additional GMO test + pesticide residue test specific to organic farming. Verified chain of custody from farm to finished product. Annual re-certification with independent OEKO-TEX institute audits.	Nothing. It is not a certification and there is no body verifying anything.	≥95% organic ingredients. No synthetic pesticides, no GMOs. Annual on-site inspection by a MAFRA-accredited certifier.	EU baseline organic (Finnish supply chains end-to-end). Annual on-site inspection by the Finnish Food Authority.
Does NOT	Doesn't certify the social/labour conditions across the supply chain in the way GOTS does (use OEKO-TEX STeP for that, or pair with GOTS). Cotton-only — doesn't apply to other organic fibres (wool, hemp, linen).	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.	Cosmetics and textiles are covered under separate Korean schemes, not this mark.	The Sun Mark is awarded only to fully Finnish supply chains — imports use the EU Leaf alone.
