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.	New Zealand's largest organic certifier. Recognised by the EU, US, and Japan under their respective import-equivalence regimes.	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.

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).	≥95% organic ingredients. No synthetic pesticides, no GMOs. Annual on-site inspection. Covers food, textiles, and personal care under separate standards.	EU baseline organic (EU 2018/848). Annual on-site inspection by accredited German certifier.
Does NOT	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.	New Zealand has no single legally-mandated 'organic' definition — voluntary certification is the norm.	Same standard as the EU Leaf — not stricter.
