OEKO-TEX® STANDARD 100 is one of the world’s best-known labels for textiles tested for harmful substances. The STANDARD 100 label guarantees that every component of a textile article, including threads, buttons, and accessories, has been tested for harmful substances and is safe for human health. The certification process is conducted by independent OEKO-TEX® partner institutes using a comprehensive criteria catalog. All textile articles in every stage of processing are eligible for certification, and each component is tested before the final article is labeled. This includes testing of prints and coatings on outer materials.
