	Global Organic Textile Standard Global · Tier 2 Trusted	Tún (Iceland) Iceland · Tier 1 Gold	EU Organic (Euro-Leaf) European Union · Tier 1 Gold	Debio Ø (Norway) Norway · Tier 2 Trusted
What it means	The strictest, most widely-recognised standard for organic textiles. Covers the full supply chain from organic fibre to finished garment, with environmental AND social criteria.	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.	The mandatory mark for any pre-packaged organic food sold in the EU. The 'Euro-Leaf' is a stylised leaf made of twelve white stars on a green background.	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.

Guarantees	≥70% certified-organic natural fibre (the 'organic' grade requires ≥95%). Restricted dyes, no chlorine bleach, no formaldehyde, no banned heavy metals. Wastewater treatment requirements. Social standards based on ILO core conventions (no child labour, no forced labour, fair wages, safe workplace). Annual on-site inspection by IOAS-accredited certifier.	≥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).	At least 95% of agricultural ingredients are organic (regulation EU 2018/848). No synthetic pesticides, no synthetic fertilizers, no GMOs. Animal welfare standards (outdoor access, lower stocking density, no routine antibiotics). Annual inspection by an accredited control body in the producing member state. Mandatory display of the certifier's code and origin (e.g. 'EU Agriculture' / 'Non-EU Agriculture').	EU baseline organic. Annual on-site inspection. Norwegian-specific welfare standards (esp. for cold-climate livestock).
Does NOT	Doesn't cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.	Doesn't ban the natural pesticides allowed under the regulation (copper sulphate, spinosad). Doesn't certify processed-food additives beyond the EU's permitted list.	Norway is outside the EU — the Ø is recognised under EEA equivalence, not direct EU equivalence.
