The Oeko-Tex Standard 100 is a globally uniform testing and certification system for textile raw materials, intermediate and end products at all stages of production.

The certification covers multiple human-ecological attributes, including harmful substances which are prohibited or regulated by law, chemicals which are known to be harmful to health, but are not officially forbidden, and parameters which are included as a precautionary measure to safeguard health.

Textile products may be certified according to Oeko-Tex Standard 100 only if all components meet the required criteria without exception.

A tested textile product is allocated to one of the four Oeko-Tex product classes based on its intended use. The more intensively a product comes into contact with the skin, the stricter the human ecological requirements it must fulfill.

Oeko-Tex Standard 100 is found on millions of products around the world in (almost) all retail segments (based on more than 65,000 certificates issued to date).
