	Bioland Germany · Tier 2 Trusted	? 'Natural' (NOT a certification) Worldwide · Tier 4 Marketing	Korea Organic South Korea · Tier 1 Gold	OTC OEKO-TEX Organic Cotton Global · Tier 2 Trusted
What it means	Germany's largest organic farmers' association. Bioland-certified farms operate to a stricter private standard than the EU baseline.	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.	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.
Scope	Food	Several categories	Food	Textiles
Established	1971	—	2001	2023
Inspection	Annual on-site by Bioland-accredited inspectors	None	Annual on-site by MAFRA-accredited certifier	Annual on-site by OEKO-TEX-accredited institute (Hohenstein et al.)
Residue testing	Required	None	Required	Required (Standard 100 panel + GMO/pesticide screening)
Guarantees	Whole-farm conversion (no parallel conventional production). Lower permitted nitrogen inputs than EU baseline. Animal welfare standards stricter than EU baseline. Annual on-site inspection.	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.	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.
Does NOT	Like Naturland, membership-based — only Bioland-association farms can use the mark.	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.	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).
