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.	National Association for Sustainable Agriculture, Australia. One of seven Australian Department of Agriculture-approved certifiers. IFOAM-accredited; certifies organic and biodynamic produce.	The European Commission's voluntary environmental label. Covers cleaning products, paper, textiles, electronics, accommodation services. NOT an organic mark.	Denmark's national organic mark, owned by the Danish Veterinary and Food Administration. The red Ø is one of the most-trusted food labels in the world — recognised by ~98% of Danish consumers.

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.	Compliance with the Australian National Standard for Organic and Bio-Dynamic Produce. Annual on-site inspection. Biodynamic certification option.	Lifecycle-based environmental criteria per product category. Restrictions on hazardous chemicals. Annual licence renewal with audit.	EU baseline organic (EU 2018/848). Annual on-site inspection by the Danish Veterinary and Food Administration. Direct government control (not a private body) — the unusual Danish model that drives high consumer trust.
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).	Australia has multiple competing organic certifiers — NASAA is one of seven, not the dominant national mark (that's ACO).	Doesn't apply to food. Doesn't mean organic.	Outside Denmark, retailers usually rely on the EU Leaf rather than the Ø.
