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.	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.	The East African regional organic mark, under the East Africa Organic Products Standard (EAOPS). Used across Kenya, Tanzania, Uganda, Rwanda, and Burundi. Administered through Participatory Guarantee Systems coordinated by KOAN (Kenya Organic Agriculture Network).	North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT organic.

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. Lower nitrogen inputs than the Swiss federal organic baseline. Strong animal welfare requirements. Annual on-site inspection.	Compliance with the East Africa Organic Products Standard (EAOPS). Peer-review inspection via Participatory Guarantee Systems (PGS). Regional cross-recognition across the five East African Community member states.	Verified absence of GMO ingredients (with action thresholds, not zero tolerance). Annual third-party verification. Tracing and segregation across the supply chain.
Does NOT	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.	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.	PGS-based — the inspection model is community peer-review rather than third-party. Strong for domestic markets, less recognised by the EU/USA than third-party schemes.	Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.
