What it means	Launched April 2023 by the OEKO-TEX Association. A separate certificate from Standard 100 that combines the Standard 100 chemical-residue test with verified organic-cotton supply chain — addressing the long-standing confusion that Standard 100 alone is NOT an organic mark.	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).	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.

Additional GMO test + pesticide residue test specific to organic farming. Verified chain of custody from farm to finished product. Annual re-certification with independent OEKO-TEX institute audits.	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.	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.
Does NOT	Doesn't certify the social/labour conditions across the supply chain in the way GOTS does (use OEKO-TEX STeP for that, or pair with GOTS). Cotton-only — doesn't apply to other organic fibres (wool, hemp, linen).	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.	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.
