	Global Organic Textile Standard Global · Tier 2 Trusted	Tún (Iceland) Iceland · Tier 1 Gold	NATRUE European Union · Tier 2 Trusted	Bio Suisse 'Knospe' (Bud) Switzerland · 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.	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.	An EU-based natural-and-organic cosmetics certification. Three grades: Natural, Natural with Organic portion, and 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.

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).	Restricted ingredient list (no synthetic fragrances, no silicones, no PEGs). Tiered organic content: Natural with Organic portion ≥70% certified organic; Organic ≥95%. Annual third-party verification.	Whole-farm conversion. Lower nitrogen inputs than the Swiss federal organic baseline. Strong animal welfare requirements. Annual on-site inspection.
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.	Mark is trademark-protected.	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.
