	OTC OEKO-TEX Organic Cotton Global · Tier 2 Trusted	EU Ecolabel (Flower) European Union · Tier 3 Specialty	Fair for Life Global · Tier 2 Trusted	Bio Suisse 'Knospe' (Bud) Switzerland · Tier 2 Trusted
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 European Commission's voluntary environmental label. Covers cleaning products, paper, textiles, electronics, accommodation services. NOT an organic mark.	Combined organic + fair-trade + social-responsibility certification. Issued by Ecocert (originally developed by IMOswiss). Stricter than baseline Fairtrade on labour conditions; often paired with an organic mark on the same product.	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.

Whole-farm conversion. Lower nitrogen inputs than the Swiss federal organic baseline. Strong animal welfare requirements. Annual on-site inspection.
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).	Doesn't apply to food. Doesn't mean organic.	Doesn't itself mean organic — pair with an organic mark for the full picture.	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.
