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 official environmental label of the Nordic countries (Sweden, Norway, Denmark, Finland, Iceland). Covers ~60 product categories from cleaning products to hotels — NOT specifically an organic standard.	Germany's national organic mark, owned by the Federal Ministry of Food and Agriculture. Sits alongside the EU Leaf on most German organic packaging since 2001. Same standard as the EU Leaf — Bio-Siegel is the brand consumers recognise.	South Korea's national organic mark under MAFRA (Ministry of Agriculture, Food and Rural Affairs). Required on any food sold as 유기농 in Korea.

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.	Lifecycle-based environmental criteria for the product category. Restrictions on hazardous chemicals. Recyclability and packaging requirements. Audited every 3-5 years against an updated standard.	EU baseline organic (EU 2018/848). Annual on-site inspection by accredited German certifier.	≥95% organic ingredients. No synthetic pesticides, no GMOs. Annual on-site inspection by a MAFRA-accredited certifier.
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 certify food as organic — Nordic Swan on a food package means lower-environmental-impact, not 'no synthetic pesticides'.	Same standard as the EU Leaf — not stricter.	Cosmetics and textiles are covered under separate Korean schemes, not this mark.
