The Step by Oeko-Tex certificate is awarded by the Oeko-Tex Community, which is part of the Hohenstein Institute, one of the most respected research facilities in the German textile industry.
Step by Oeko-Tex was launched in 2014, replacing Oeko-Tex Standard 1000. Even more famous is Standard 100 by Oeko-Tex, although this only tests the health safety of products, and not the entire production chain like Step by Oeko-Tex does.
Step stands for Sustainable Textile Production, and is used to certify production plants at all processing stages, from fiber production to spinning and weaving/knitting, all the way up to refinement plants and manufacturers.
The Step by Oeko-Tex certification divides the topic of sustainability into six different modules: chemicals and their use, environmental performance, environmental management, social responsibility, quality management, and occupational health and safety.
