What it means	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.	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 mandatory mark for any pre-packaged organic food sold in the EU. The 'Euro-Leaf' is a stylised leaf made of twelve white stars on a green background.

Annual on-site inspection by a MAFRA-accredited certifier.	≥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).	At least 95% of agricultural ingredients are organic (regulation EU 2018/848). No synthetic pesticides, no synthetic fertilizers, no GMOs. Animal welfare standards (outdoor access, lower stocking density, no routine antibiotics). Annual inspection by an accredited control body in the producing member state. Mandatory display of the certifier's code and origin (e.g. 'EU Agriculture' / 'Non-EU Agriculture').
Does NOT	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.	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.	Doesn't ban the natural pesticides allowed under the regulation (copper sulphate, spinosad). Doesn't certify processed-food additives beyond the EU's permitted list.
