	Non-GMO Project Verified United States · Tier 3 Specialty	Tún (Iceland) Iceland · Tier 1 Gold	Nordic Swan Ecolabel Nordic Countries · Tier 3 Specialty	USDA Organic United States · Tier 1 Gold
What it means	North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT organic.	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 official environmental label of the Nordic countries (Sweden, Norway, Denmark, Finland, Iceland). Covers ~60 product categories from cleaning products to hotels — NOT specifically an organic standard.	The US Department of Agriculture's national organic standard. The green-and-white seal is the legal mark for any food sold as 'organic' in the United States.
Scope	Food	Food	Several categories	Food
Established	2010	1994	1989	2002

Residue testing	GMO testing only (not pesticide)	Required for at-risk operations	Risk-based per category	Required on ≥5% of operations annually
Guarantees	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 per EU rules. No synthetic pesticides, no GMOs. Annual on-site inspection. Animal welfare standards (outdoor / pasture access, geothermally-warmed greenhouse compatibility for vegetables).	Lifecycle-based environmental criteria for the product category. Restrictions on hazardous chemicals. Recyclability and packaging requirements. Audited every 3-5 years against an updated standard.	At least 95% of ingredients are certified organic (the '100% Organic' variant requires every ingredient). No synthetic pesticides, no synthetic fertilizers, no GMOs, no sewage sludge, no irradiation. Annual on-site inspection by a USDA-accredited certifier. Residue testing on at least 5% of certified operations each year.
Does NOT	Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.	Doesn't certify food as organic — Nordic Swan on a food package means lower-environmental-impact, not 'no synthetic pesticides'.	Doesn't certify nutrition, taste, or animal welfare specifically (separate marks like AWA cover welfare). Doesn't guarantee local production — a 'USDA Organic' product can be grown anywhere with an accredited inspector.
