	$OEKO-TEX Standard 100 logo$ OEKO-TEX Standard 100 Global · Tier 3 Specialty	Tún (Iceland) Iceland · Tier 1 Gold	Non-GMO Project Verified United States · Tier 3 Specialty	IFM IFOAM — Organics International Global · Tier 2 Trusted
What it means	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.	North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT organic.	The international umbrella body for the organic movement. Not a product label — IFOAM accredits other certifiers worldwide via the IFOAM Family of Standards. If a cert is 'IFOAM-accredited' it has been benchmarked to a globally consistent baseline.
Scope	Textiles	Food	Food	Several categories
Established	1992	1994	2010	1972
Inspection	Annual on-site + lab testing of finished products	Annual on-site, MAST-accredited	Annual third-party audit + lab testing	Periodic review of accredited certifier bodies
Residue testing	Required (this is the entire point)	Required for at-risk operations	GMO testing only (not pesticide)	Delegated to accredited certifiers
Guarantees	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).	Verified absence of GMO ingredients (with action thresholds, not zero tolerance). Annual third-party verification. Tracing and segregation across the supply chain.	Accredited certifiers meet the IFOAM Norms and the IFOAM Family of Standards. Independent peer review of certifier governance, inspection rigor, and conflict-of-interest controls.
Does NOT	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.	Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.	Does NOT certify products directly — only certifiers. Look for the underlying national / private mark on the package.
