	OTC OEKO-TEX Organic Cotton Global · Tier 2 Trusted	Luomu (Finland) Finland · Tier 2 Trusted	Debio Ø (Norway) Norway · Tier 2 Trusted	Tún (Iceland) Iceland · Tier 1 Gold
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.	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.	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.	Vottunarstofan Tún is Iceland's only accredited organic certifier. Accredited by MAST (Matvælastofnun) under the EU 2018/848-equivalent Icelandic standard, so a Tún-certified product is also recognised as EU-organic.

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.	EU baseline organic (Finnish supply chains end-to-end). Annual on-site inspection by the Finnish Food Authority.	EU baseline organic. Annual on-site inspection. Norwegian-specific welfare standards (esp. for cold-climate livestock).	≥95% organic ingredients per EU rules. No synthetic pesticides, no GMOs. Annual on-site inspection. Animal welfare standards (outdoor / pasture access, geothermally-warmed greenhouse compatibility for vegetables).
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).	The Sun Mark is awarded only to fully Finnish supply chains — imports use the EU Leaf alone.	Norway is outside the EU — the Ø is recognised under EEA equivalence, not direct EU equivalence.	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.
