What it means	France-based independent certifier operating in 130+ countries. One of the world's largest organic + cosmetics + textile certifiers. The 'Ecocert' wordmark on a package usually means Ecocert was the accredited body that ran the inspection against the national/EU standard.	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 strictest, most widely-recognised standard for organic textiles. Covers the full supply chain from organic fibre to finished garment, with environmental AND social criteria.	North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT organic.
Scope	Several categories	Food	Textiles	Food
Established	1991	1994	2002	2010
Inspection	Annual on-site, ISO 17065-accredited	Annual on-site, MAST-accredited	Annual on-site, IOAS-accredited	Annual third-party audit + lab testing
Residue testing	Risk-based per standard	Required for at-risk operations	Required for finished products	GMO testing only (not pesticide)
Guarantees	Inspection against the relevant national or private organic standard (EU 2018/848, USDA NOP, COSMOS, GOTS, Fair for Life, etc.). Annual on-site inspection. Accredited under multiple national systems including USDA NOP and EU 2018/848.	≥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).	≥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.	Verified absence of GMO ingredients (with action thresholds, not zero tolerance). Annual third-party verification. Tracing and segregation across the supply chain.
Does NOT	Ecocert is the certifier, not the standard — the actual rules come from whichever organic regulation the product is certified under.	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.	Doesn't cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.	Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.
