	Tún (Iceland) Iceland · Tier 1 Gold	Luomu (Finland) Finland · Tier 2 Trusted	Bio-Siegel (Germany) Germany · Tier 1 Gold	$OEKO-TEX Standard 100 logo$ OEKO-TEX Standard 100 Global · Tier 3 Specialty
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.	Finland's national organic 'Sun Mark' (Aurinkomerkki). Operated by the Finnish Food Authority. In practice most Finnish organic packaging carries both Luomu and the EU Leaf — they certify to the same baseline.	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.	Tests finished textiles for harmful substances. Important: OEKO-TEX 100 is NOT an organic certification — it certifies that the finished item is free of certain chemicals, regardless of how the fibre was grown.

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).	EU baseline organic (Finnish supply chains end-to-end). Annual on-site inspection by the Finnish Food Authority.	EU baseline organic (EU 2018/848). Annual on-site inspection by accredited German certifier.	Finished textile tested against the OEKO-TEX harmful-substance limit list. Limits on heavy metals, formaldehyde, pesticide residue, banned amines, allergenic dyes.
Does NOT	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.	The Sun Mark is awarded only to fully Finnish supply chains — imports use the EU Leaf alone.	Same standard as the EU Leaf — not stricter.	Does NOT mean organic. Does NOT cover farming, dyeing chemistry beyond the limit list, or social/labour standards. A 100% conventional cotton t-shirt can be OEKO-TEX 100 certified.
