What it means	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.	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.	The international umbrella body for the organic movement. Not a product label — IFOAM accredits other certifiers worldwide via the IFOAM Family of Standards. If a cert is 'IFOAM-accredited' it has been benchmarked to a globally consistent baseline.
Scope	Food	Food	Food	Several categories

Guarantees	EU baseline organic (EU 2018/848). Annual on-site inspection by accredited German certifier.	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).	Accredited certifiers meet the IFOAM Norms and the IFOAM Family of Standards. Independent peer review of certifier governance, inspection rigor, and conflict-of-interest controls.
Does NOT	Same standard as the EU Leaf — not stricter.	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.	Does NOT certify products directly — only certifiers. Look for the underlying national / private mark on the package.
