	OTC OEKO-TEX Organic Cotton Global · Tier 2 Trusted	Non-GMO Project Verified United States · Tier 3 Specialty	Debio Ø (Norway) Norway · Tier 2 Trusted	Canada Organic Biologique Canada · 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.	North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT organic.	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.	The federal Canadian organic standard, mandatory on any agricultural product sold across provincial borders or imported as 'organic'.
Scope	Textiles	Food	Food	Food

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.	Verified absence of GMO ingredients (with action thresholds, not zero tolerance). Annual third-party verification. Tracing and segregation across the supply chain.	EU baseline organic. Annual on-site inspection. Norwegian-specific welfare standards (esp. for cold-climate livestock).	≥95% organic ingredients (single-ingredient products: 100%). No synthetic pesticides, no GMOs, no irradiation. Annual third-party certification under the Canada Organic Regime.
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 mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.	Norway is outside the EU — the Ø is recognised under EEA equivalence, not direct EU equivalence.	Provincial sales-only operations are not legally required to carry it (though many do voluntarily).
