What it means	South Korea's national organic mark under MAFRA (Ministry of Agriculture, Food and Rural Affairs). Required on any food sold as 유기농 in Korea.	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.	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.	North America's leading 'no genetically modified organisms' certification. Tests for the presence of GMOs in finished products. NOT organic.

Guarantees	≥95% organic ingredients. No synthetic pesticides, no GMOs. Annual on-site inspection by a MAFRA-accredited 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.	EU baseline organic (EU 2018/848). Annual on-site inspection by accredited German certifier.	Verified absence of GMO ingredients (with action thresholds, not zero tolerance). Annual third-party verification. Tracing and segregation across the supply chain.
Does NOT	Cosmetics and textiles are covered under separate Korean schemes, not this mark.	Doesn't cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.	Same standard as the EU Leaf — not stricter.	Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.
