What it means	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.	China's national organic certification under the Certification and Accreditation Administration. Mandatory on any product sold as '有机' (organic) in mainland China.	The Swiss organic farmers' federation mark. The Knospe (Bud) is the dominant organic mark in Swiss supermarkets and operates to standards stricter than the Swiss federal organic ordinance.

Guarantees	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).	≥95% organic ingredients. No synthetic pesticides, no GMOs. Annual third-party certification. Each certified product carries a unique 17-digit traceability code.	Whole-farm conversion. Lower nitrogen inputs than the Swiss federal organic baseline. Strong animal welfare requirements. Annual on-site inspection.
Does NOT	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.	Imported organic foods must be re-certified under the Chinese standard — overseas certifications alone are not accepted for the 有机 label.	Switzerland is outside the EU — the Knospe is recognised by the EU under the Switzerland-EU equivalence agreement, but not by USDA without further certification.
