	Tún (Iceland) Iceland · Tier 1 Gold	Bioland Germany · Tier 2 Trusted	? 'Natural' (NOT a certification) Worldwide · Tier 4 Marketing	EU Ecolabel (Flower) European Union · Tier 3 Specialty
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.	Germany's largest organic farmers' association. Bioland-certified farms operate to a stricter private standard than the EU baseline.	The word 'natural' on packaging is a marketing term, not a certification. In most jurisdictions there's no legal definition, no standard, and no inspection. A product labelled 'natural' can contain synthetic ingredients, pesticides, GMOs, and artificial flavours.	The European Commission's voluntary environmental label. Covers cleaning products, paper, textiles, electronics, accommodation services. NOT an organic mark.

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).	Whole-farm conversion (no parallel conventional production). Lower permitted nitrogen inputs than EU baseline. Animal welfare standards stricter than EU baseline. Annual on-site inspection.	Nothing. It is not a certification and there is no body verifying anything.	Lifecycle-based environmental criteria per product category. Restrictions on hazardous chemicals. Annual licence renewal with audit.
Does NOT	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.	Like Naturland, membership-based — only Bioland-association farms can use the mark.	Doesn't mean organic. Doesn't mean pesticide-free. Doesn't mean GMO-free. Doesn't mean ethically produced. Some markets (e.g. the US FDA on food, EU on cosmetics) place very limited restrictions on the word, but enforcement is weak.	Doesn't apply to food. Doesn't mean organic.
