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.	An EU-based natural-and-organic cosmetics certification. Three grades: Natural, Natural with Organic portion, and Organic.	The certification mark for biodynamic agriculture. Stricter than any government organic standard: it covers the entire farm as a closed ecosystem, follows a planting calendar tied to lunar/solar cycles, and bans many practices the baseline organic rules permit.
Scope	Food	Food	Cosmetics	Several categories
Established	2010	1994	2007	1928
Inspection	Annual third-party audit + lab testing	Annual on-site, MAST-accredited	Annual third-party audit	Annual on-site by Demeter-accredited inspectors
Residue testing	GMO testing only (not pesticide)	Required for at-risk operations	Risk-based	Risk-based on top of organic
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).	Restricted ingredient list (no synthetic fragrances, no silicones, no PEGs). Tiered organic content: Natural with Organic portion ≥70% certified organic; Organic ≥95%. Annual third-party verification.	All organic standards PLUS biodynamic preparations and whole-farm planning. Whole-farm certification (not single fields/products). Annual on-site inspection by Demeter-accredited inspectors. Animal welfare standards stricter than baseline organic.
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.	Mark is trademark-protected.	Biodynamic philosophy includes esoteric elements (lunar planting, herbal preparations) that many scientists view as non-evidence-based — the agronomic outcomes are still good, the underlying claims about cosmic forces are not testable.
