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.	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.	The Swiss organic farmers' federation mark. The Knospe (Bud) is the dominant organic mark in Swiss supermarkets and operates to standards stricter than the Swiss federal organic ordinance.	Germany's largest organic farmers' association. Bioland-certified farms operate to a stricter private standard than the EU baseline.

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).	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.	Whole-farm conversion. Lower nitrogen inputs than the Swiss federal organic baseline. Strong animal welfare requirements. Annual on-site inspection.	Whole-farm conversion (no parallel conventional production). Lower permitted nitrogen inputs than EU baseline. Animal welfare standards stricter than EU baseline. Annual on-site inspection.
Does NOT	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.	Newer label (2018+) — supply still limited, mostly US brands.	Switzerland is outside the EU — the Knospe is recognised by the EU under the Switzerland-EU equivalence agreement, but not by USDA without further certification.	Like Naturland, membership-based — only Bioland-association farms can use the mark.
