What it means	North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT 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.	A German farmers' association whose private organic standard is stricter than the EU baseline. Covers food, aquaculture, textiles, and cosmetics. Recognised globally.	Norway's only accredited organic certifier. The Ø-merket is required on any food sold as 'økologisk' in Norway. Operates to EU 2018/848 equivalence plus Norwegian add-ons.

Guarantees	Verified absence of GMO ingredients (with action thresholds, not zero tolerance). Annual third-party verification. Tracing and segregation across the supply chain.	EU baseline organic (EU 2018/848). Annual on-site inspection by accredited German certifier.	Stricter than EU 2018/848 (lower nitrogen inputs, full-farm conversion, social standards). Annual on-site inspection. Fair-pricing requirements for member farmers.	EU baseline organic. Annual on-site inspection. Norwegian-specific welfare standards (esp. for cold-climate livestock).
Does NOT	Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.	Same standard as the EU Leaf — not stricter.	Membership-based — only farms that join the Naturland association can use the mark.	Norway is outside the EU — the Ø is recognised under EEA equivalence, not direct EU equivalence.
