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.	An EU-based natural-and-organic cosmetics certification. Three grades: Natural, Natural with Organic portion, and Organic.	Germany's national organic mark, owned by the Federal Ministry of Food and Agriculture. Sits alongside the EU Leaf on most German organic packaging since 2001. Same standard as the EU Leaf — Bio-Siegel is the brand consumers recognise.	National Association for Sustainable Agriculture, Australia. One of seven Australian Department of Agriculture-approved certifiers. IFOAM-accredited; certifies organic and biodynamic produce.

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).	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.	EU baseline organic (EU 2018/848). Annual on-site inspection by accredited German certifier.	Compliance with the Australian National Standard for Organic and Bio-Dynamic Produce. Annual on-site inspection. Biodynamic certification option.
Does NOT	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.	Same standard as the EU Leaf — not stricter.	Australia has multiple competing organic certifiers — NASAA is one of seven, not the dominant national mark (that's ACO).
