	Global Organic Textile Standard Global · Tier 2 Trusted	Tún (Iceland) Iceland · Tier 1 Gold	? 'Natural' (NOT a certification) Worldwide · Tier 4 Marketing	Canada Organic Biologique Canada · 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.	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 word 'natural' on packaging is a marketing term, not a certification. In most jurisdictions there's no legal definition, no standard, and no inspection. A product labelled 'natural' can contain synthetic ingredients, pesticides, GMOs, and artificial flavours.	The federal Canadian organic standard, mandatory on any agricultural product sold across provincial borders or imported as 'organic'.
Scope	Textiles	Food	Several categories	Food
Established	2002	1994	—	2009
Inspection	Annual on-site, IOAS-accredited	Annual on-site, MAST-accredited	None	Annual on-site by CFIA-accredited certifier
Residue testing	Required for finished products	Required for at-risk operations	None	Risk-based, conducted by accredited certifiers
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).	Nothing. It is not a certification and there is no body verifying anything.	≥95% organic ingredients (single-ingredient products: 100%). No synthetic pesticides, no GMOs, no irradiation. Annual third-party certification under the Canada Organic Regime.
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 mean organic. Doesn't mean pesticide-free. Doesn't mean GMO-free. Doesn't mean ethically produced. Some markets (e.g. the US FDA on food, EU on cosmetics) place very limited restrictions on the word, but enforcement is weak.	Provincial sales-only operations are not legally required to carry it (though many do voluntarily).
