What it means	The European Commission's voluntary environmental label. Covers cleaning products, paper, textiles, electronics, accommodation services. NOT an organic mark.	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.	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.	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).

No synthetic pesticides, no GMOs. Annual on-site inspection. Animal welfare standards (outdoor / pasture access, geothermally-warmed greenhouse compatibility for vegetables).	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.	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.
Does NOT	Doesn't apply to food. Doesn't mean organic.	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.	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 certify clinical effectiveness or skin tolerance.
