What it meansLaunched 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.South Korea's national organic mark under MAFRA (Ministry of Agriculture, Food and Rural Affairs). Required on any food sold as 유기농 in Korea.Norway's only accredited organic certifier. The Ø-merket is required on any food sold as 'økologisk' in Norway. Operates to EU 2018/848 equivalence plus Norwegian add-ons.

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).
  • Cosmetics and textiles are covered under separate Korean schemes, not this mark.
  • Norway is outside the EU — the Ø is recognised under EEA equivalence, not direct EU equivalence.
