Leather Standard by Oeko-Tex
Logo of Leather Standard by Oeko-Tex
The Leather Standard by Oeko-Tex (introduced 2017) is a system of testing methods, test criteria and limit values for harmful substances used by the Oeko-Tex member institutes to globally certify the human-ecological safety of leather products: semi-finished leather materials (“Wet blue” – chrome-tanned hides, “Wet white” – vegetable tanned hides), leather, bonded leather and ready-made leather articles. When certifying leather products that contain non-leather (e.g. textile or metallic) components, the requirements of the Leather Standard are combined with those of the Standard 100. Certification according to the Leather Standard is valid for one year.
The Leather Standard defines the same four product classes as the Standard 100. Both also employ very similar catalogues of limit values for potentially harmful chemicals. Mainly, for the Leather Standard, Oeko-Tex has adjusted the limit values for Chromium: Since industrially produced leather is predominantly chrome-tanned, higher Chromium concentrations are tolerated in leather compared to textile products.[
