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.	North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT organic.	A 'beyond organic' standard developed by the Regenerative Organic Alliance (Patagonia, Rodale Institute, Dr. Bronner's, others). Built on top of USDA Organic; adds soil health, animal welfare, and social fairness pillars.

Annual on-site inspection by a MAFRA-accredited certifier.	Verified absence of GMO ingredients (with action thresholds, not zero tolerance). Annual third-party verification. Tracing and segregation across the supply chain.	USDA Organic baseline (or equivalent) is a prerequisite. Soil health: cover cropping, no-till or reduced-till, conservation crop rotation, compost. Animal welfare: pasture-based, Five Freedoms, prohibits factory-farm conditions. Social fairness: living wage, freedom of association, safe workplace, no forced or child labour. Three tiers: Bronze, Silver, Gold based on adoption depth.
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.	Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.	Newer label (2018+) — supply still limited, mostly US brands.
