What it means	North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT organic.	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.	Sweden's leading organic mark. Built on the EU 2018/848 baseline plus stricter Swedish add-ons covering animal welfare, climate impact, and social conditions.

Guarantees	Verified absence of GMO ingredients (with action thresholds, not zero tolerance). Annual third-party verification. Tracing and segregation across the supply chain.	≥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).	EU baseline organic PLUS Swedish-specific welfare and climate add-ons. Annual on-site inspection. Climate footprint accounting on KRAV-certified farms.
Does NOT	Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.	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.	Mark is trademark-protected.
