STANDARD 100 by OEKO-TEX—STANDARD 100 is an eco-label that ensures that textile products do not contain substances at levels hazardous to health. For a product to be labelled STANDARD 100, every component and every stage of production, from thread to fabric to finished product, has been tested for substances according to OEKO-TEX criteria. The label covers not only substances that are banned but also those suspected of having negative effects on health.
LEATHER STANDARD by OEKO-TEX— LEATHER STANDARD is the equivalent of STANDARD 100 for leather and leather products and ensures that the product does not contain harmful substances. Like STANDARD 100, LEATHER STANDARD labels everything from leather to finished leather products, excluding leather from exotic or protected species like crocodiles and snakes.
