	OTC OEKO-TEX Organic Cotton Global · Tier 2 Trusted	Luomu (Finland) Finland · Tier 2 Trusted	Debio Ø (Norway) Norway · Tier 2 Trusted	Australian Certified Organic Australia · 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.	Australia's largest organic certifier, accredited under the Australian National Standard for Organic and Bio-Dynamic Produce. The bud-and-leaf logo is the most-seen organic mark in Australian supermarkets.

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. No synthetic pesticides, no GMOs. Annual on-site inspection. Animal welfare and biodynamic-compatible production options.
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.	Australia has no single mandatory organic mark — ACO is the dominant one, but NASAA, OFC, and others also certify.
