	Tún (Iceland) Iceland · Tier 1 Gold	Non-GMO Project Verified United States · Tier 3 Specialty	Korea Organic South Korea · Tier 1 Gold
What it means	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.	South Korea's national organic mark under MAFRA (Ministry of Agriculture, Food and Rural Affairs). Required on any food sold as 유기농 in Korea.
Scope	Food	Food	Food
Established	1994	2010	2001
Inspection	Annual on-site, MAST-accredited	Annual third-party audit + lab testing	Annual on-site by MAFRA-accredited certifier
Residue testing	Required for at-risk operations	GMO testing only (not pesticide)	Required
Guarantees	≥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.	≥95% organic ingredients. No synthetic pesticides, no GMOs. Annual on-site inspection by a MAFRA-accredited certifier.
Does NOT	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.	Cosmetics and textiles are covered under separate Korean schemes, not this mark.
