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.	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	Whole-farm conversion. Lower nitrogen inputs than the Swiss federal organic baseline. Strong animal welfare requirements. Annual on-site inspection.	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	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.	Membership-based — only farms that join the Naturland association can use the mark.	Same standard as the EU Leaf — not stricter.
