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 German farmers' association whose private organic standard is stricter than the EU baseline. Covers food, aquaculture, textiles, and cosmetics. Recognised globally.	North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT organic.	The leading certification for organic cosmetics in Europe. Two grades: COSMOS Organic (≥95% organic agricultural ingredients) and COSMOS Natural (no organic minimum, but the same restricted-ingredient list).

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).	Stricter than EU 2018/848 (lower nitrogen inputs, full-farm conversion, social standards). Annual on-site inspection. Fair-pricing requirements for member farmers.	Verified absence of GMO ingredients (with action thresholds, not zero tolerance). Annual third-party verification. Tracing and segregation across the supply chain.	COSMOS Organic: ≥95% organic agricultural ingredients. COSMOS Natural: minimum natural-origin ingredients with banned synthetic restrictions. No GMOs, no parabens, no PEGs, no synthetic fragrances, no SLS/SLES. Biodegradability requirements. Annual on-site audit.
Does NOT	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.	Membership-based — only farms that join the Naturland association can use the mark.	Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.	Doesn't certify clinical effectiveness or skin tolerance.
