What it means	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.	The strictest, most widely-recognised standard for organic textiles. Covers the full supply chain from organic fibre to finished garment, with environmental AND social criteria.	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.	Japan's national organic standard under the Japanese Agricultural Standard system. The mark must appear on any food sold as 'organic' (有機 or オーガニック) in Japan.

Guarantees	EU baseline organic (EU 2018/848). Annual on-site inspection by accredited German certifier.	≥70% certified-organic natural fibre (the 'organic' grade requires ≥95%). Restricted dyes, no chlorine bleach, no formaldehyde, no banned heavy metals. Wastewater treatment requirements. Social standards based on ILO core conventions (no child labour, no forced labour, fair wages, safe workplace). Annual on-site inspection by IOAS-accredited certifier.	≥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).	≥95% organic ingredients. No synthetic pesticides, no synthetic fertilizers, no GMOs. Annual inspection by a MAFF-registered certifier.
Does NOT	Same standard as the EU Leaf — not stricter.	Doesn't cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.	There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.	Mutual recognition with the US, EU, and Canada applies to specific product categories — check each agreement before importing.
