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

Does NOT	Doesn't mean organic — Non-GMO products can use synthetic pesticides and fertilizers freely.	Cosmetics and textiles are covered under separate Korean schemes, not this mark.	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.
