	Global Organic Textile Standard Global · Tier 2 Trusted	Naturland Germany · Tier 2 Trusted	Rainforest Alliance Global · Tier 3 Specialty	Tún (Iceland) Iceland · 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.	A German farmers' association whose private organic standard is stricter than the EU baseline. Covers food, aquaculture, textiles, and cosmetics. Recognised globally.	Sustainable-agriculture certification (post-2020 merged standard with UTZ). Covers environmental, social, and economic criteria. NOT an organic mark.	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.
Scope	Textiles	Several categories	Food	Food

Residue testing	Required for finished products	Required	Risk-based	Required for at-risk operations
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.	Stricter than EU 2018/848 (lower nitrogen inputs, full-farm conversion, social standards). Annual on-site inspection. Fair-pricing requirements for member farmers.	Reduced (not eliminated) synthetic pesticide use, with bans on the most hazardous classes. Forest conservation requirements (no deforestation after the cut-off date). Worker welfare and community development requirements. Annual third-party audit.	≥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).
Does NOT	Doesn't cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.	Membership-based — only farms that join the Naturland association can use the mark.	Allows synthetic pesticides — does NOT meet any organic standard. Often confused with organic but it's a different programme.	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.
