What it meansTests 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.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 international umbrella body for the organic movement. Not a product label — IFOAM accredits other certifiers worldwide via the IFOAM Family of Standards. If a cert is 'IFOAM-accredited' it has been benchmarked to a globally consistent baseline.
