What it means	Germany's largest organic farmers' association. Bioland-certified farms operate to a stricter private standard than the EU baseline.	Australia's largest organic certifier, accredited under the Australian National Standard for Organic and Bio-Dynamic Produce. The bud-and-leaf logo is the most-seen organic mark in Australian supermarkets.	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.

Animal welfare and biodynamic-compatible production options.	≥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).
Does NOT	Like Naturland, membership-based — only Bioland-association farms can use the mark.	Australia has no single mandatory organic mark — ACO is the dominant one, but NASAA, OFC, and others also certify.	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.
