	Bio Suisse 'Knospe' (Bud) Switzerland · Tier 2 Trusted	Rainforest Alliance Global · Tier 3 Specialty	Bioland Germany · Tier 2 Trusted	Tún (Iceland) Iceland · Tier 1 Gold
What it means	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.	Sustainable-agriculture certification (post-2020 merged standard with UTZ). Covers environmental, social, and economic criteria. NOT an organic mark.	Germany's largest organic farmers' association. Bioland-certified farms operate to a stricter private standard than the EU baseline.	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.

Guarantees	Whole-farm conversion. Lower nitrogen inputs than the Swiss federal organic baseline. Strong animal welfare requirements. Annual on-site inspection.	Reduced (not eliminated) synthetic pesticide use, with bans on the most hazardous classes. Forest conservation requirements (no deforestation after the cut-off date). Worker welfare and community development requirements. Annual third-party audit.	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.	≥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	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.	Allows synthetic pesticides — does NOT meet any organic standard. Often confused with organic but it's a different programme.	Like Naturland, membership-based — only Bioland-association farms can use the mark.	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.
