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.	South Korea's national organic mark under MAFRA (Ministry of Agriculture, Food and Rural Affairs). Required on any food sold as 유기농 in Korea.	South America's largest organic certifier. IBD certifies under Brazilian, USDA NOP, EU, and JAS standards — a single-stop certifier widely used across Latin America.	North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT organic.

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).	≥95% organic ingredients. No synthetic pesticides, no GMOs. Annual on-site inspection by a MAFRA-accredited certifier.	Multiple-standard certification: Brazilian (SisOrg), USDA NOP, EU, JAS, Demeter. Annual on-site inspection.	Verified absence of GMO ingredients (with action thresholds, not zero tolerance). Annual third-party verification. Tracing and segregation across the supply chain.
Does NOT	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.	Cosmetics and textiles are covered under separate Korean schemes, not this mark.	A single product may carry IBD plus a country-specific organic mark — IBD itself isn't the regulatory mark in any of those markets, just the accredited certifier.	Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.
