What it means	National Association for Sustainable Agriculture, Australia. One of seven Australian Department of Agriculture-approved certifiers. IFOAM-accredited; certifies organic and biodynamic produce.	Tests finished textiles for harmful substances. Important: OEKO-TEX 100 is NOT an organic certification — it certifies that the finished item is free of certain chemicals, regardless of how the fibre was grown.	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 federal Canadian organic standard, mandatory on any agricultural product sold across provincial borders or imported as 'organic'.
Scope	Several categories	Textiles	Food	Food
Established	1986	1992	1994	2009
Inspection	Annual on-site, NASAA-accredited	Annual on-site + lab testing of finished products	Annual on-site, MAST-accredited	Annual on-site by CFIA-accredited certifier
Residue testing	Risk-based	Required (this is the entire point)	Required for at-risk operations	Risk-based, conducted by accredited certifiers
Guarantees	Compliance with the Australian National Standard for Organic and Bio-Dynamic Produce. Annual on-site inspection. Biodynamic certification option.	Finished textile tested against the OEKO-TEX harmful-substance limit list. Limits on heavy metals, formaldehyde, pesticide residue, banned amines, allergenic dyes.	≥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).	≥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	Australia has multiple competing organic certifiers — NASAA is one of seven, not the dominant national mark (that's ACO).	Does NOT mean organic. Does NOT cover farming, dyeing chemistry beyond the limit list, or social/labour standards. A 100% conventional cotton t-shirt can be OEKO-TEX 100 certified.	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.	Provincial sales-only operations are not legally required to carry it (though many do voluntarily).
