	Global Organic Textile Standard Global · Tier 2 Trusted	Canada Organic Biologique Canada · Tier 1 Gold	Bio Suisse 'Knospe' (Bud) Switzerland · Tier 2 Trusted	Demeter International Global · Tier 2 Trusted
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.	The federal Canadian organic standard, mandatory on any agricultural product sold across provincial borders or imported as 'organic'.	The Swiss organic farmers' federation mark. The Knospe (Bud) is the dominant organic mark in Swiss supermarkets and operates to standards stricter than the Swiss federal organic ordinance.	The certification mark for biodynamic agriculture. Stricter than any government organic standard: it covers the entire farm as a closed ecosystem, follows a planting calendar tied to lunar/solar cycles, and bans many practices the baseline organic rules permit.
Scope	Textiles	Food	Food	Several categories
Established	2002	2009	1981	1928
Inspection	Annual on-site, IOAS-accredited	Annual on-site by CFIA-accredited certifier	Annual on-site, bio.inspecta accredited	Annual on-site by Demeter-accredited inspectors
Residue testing	Required for finished products	Risk-based, conducted by accredited certifiers	Required	Risk-based on top of organic
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 (single-ingredient products: 100%). No synthetic pesticides, no GMOs, no irradiation. Annual third-party certification under the Canada Organic Regime.	Whole-farm conversion. Lower nitrogen inputs than the Swiss federal organic baseline. Strong animal welfare requirements. Annual on-site inspection.	All organic standards PLUS biodynamic preparations and whole-farm planning. Whole-farm certification (not single fields/products). Annual on-site inspection by Demeter-accredited inspectors. Animal welfare standards stricter than baseline organic.
Does NOT	Doesn't cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.	Provincial sales-only operations are not legally required to carry it (though many do voluntarily).	Switzerland is outside the EU — the Knospe is recognised by the EU under the Switzerland-EU equivalence agreement, but not by USDA without further certification.	Biodynamic philosophy includes esoteric elements (lunar planting, herbal preparations) that many scientists view as non-evidence-based — the agronomic outcomes are still good, the underlying claims about cosmic forces are not testable.
