To have a textile or leather product certified by Oeko-Tex, manufacturers must supply samples of all components (including accessories like buttons, zips, studs, sewing threads, labels or prints) for analysis to a laboratory at one of the Oeko-Tex member institutes. The Oeko-Tex certificate is issued after successful testing of the materials for compliance with the Oeko-Tex standards and the signing of a declaration of conformity. Part of the certification process is also a company audit at the certified item’s production facility, conducted shortly prior or after the issuing of the certificate. Later on, audits take place at least every three years.
To verify continued compliance with the required limit values, the Oeko-Tex Association carries out annual checks for at least 25% of all issued Standard 100 and Leather Standard certificates.These checks involve unannounced company visits and laboratory tests of labelled product samples acquired from stores and production sites. Current information about withdrawn certificates is provided on the Oeko-Tex website.
To ensure continued compliance with the requirements in the case of STeP certificates, Oeko-Tex carries out unannounced on-site visits at the production facilities.
