	China Organic (COFCC) China · Tier 1 Gold	Tún (Iceland) Iceland · Tier 1 Gold	Naturland Germany · Tier 2 Trusted	Bio-Siegel (Germany) Germany · Tier 1 Gold
What it means	China's national organic certification under the Certification and Accreditation Administration. Mandatory on any product sold as '有机' (organic) in mainland China.	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.	A German farmers' association whose private organic standard is stricter than the EU baseline. Covers food, aquaculture, textiles, and cosmetics. Recognised globally.	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. No synthetic pesticides, no GMOs. Annual third-party certification. Each certified product carries a unique 17-digit traceability code.	≥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).	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 (EU 2018/848). Annual on-site inspection by accredited German certifier.
Does NOT	Imported organic foods must be re-certified under the Chinese standard — overseas certifications alone are not accepted for the 有机 label.	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.	Membership-based — only farms that join the Naturland association can use the mark.	Same standard as the EU Leaf — not stricter.
