	Global Organic Textile Standard Global · Tier 2 Trusted	Soil Association Organic United Kingdom · Tier 2 Trusted	COSMOS-Organic / Natural European Union · Tier 2 Trusted	Tún (Iceland) Iceland · Tier 1 Gold
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.	The UK's largest organic certifier. Standards are stricter than the UK government's baseline (which still mirrors EU 2018/848 post-Brexit). Recognised by the EU and USA under equivalence.	The leading certification for organic cosmetics in Europe. Two grades: COSMOS Organic (≥95% organic agricultural ingredients) and COSMOS Natural (no organic minimum, but the same restricted-ingredient list).	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.

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.	Stricter-than-baseline organic standards across food, textiles, cosmetics, and farming. Annual on-site inspection. Animal welfare standards (outdoor access, lower stocking density).	COSMOS Organic: ≥95% organic agricultural ingredients. COSMOS Natural: minimum natural-origin ingredients with banned synthetic restrictions. No GMOs, no parabens, no PEGs, no synthetic fragrances, no SLS/SLES. Biodegradability requirements. Annual on-site audit.	≥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 cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.	Logo is trademarked — not a free-licence mark.	Doesn't certify clinical effectiveness or skin tolerance.	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.
