What it means	The federal Canadian organic standard, mandatory on any agricultural product sold across provincial borders or imported as 'organic'.	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 strictest, most widely-recognised standard for organic textiles. Covers the full supply chain from organic fibre to finished garment, with environmental AND social criteria.	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.

Guarantees	≥95% organic ingredients (single-ingredient products: 100%). No synthetic pesticides, no GMOs, no irradiation. Annual third-party certification under the Canada Organic Regime.	≥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).	≥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.	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.
Does NOT	Provincial sales-only operations are not legally required to carry it (though many do voluntarily).	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.	Doesn't cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.	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).
