exceed 5% of the total product weight are STeP certified, and 4. at least 85% of the total weight of the total product weight is supplied by STeP certified wet/chemical production facilities. This means that minor, light-weight components like sewing thread, while required to be free from harmful substances according to Standard 100, don't necessarily have to be produced in STeP certified facilities. A unique product ID and/or QR code on the Made in Green label enables consumers to trace the production of the labelled textile article: Scanning the code or entering the product ID on the Made in Green website reveals the countries where the item was made and which production stages and facilities (provided the manufacturers have released this information) were involved in the manufacturing. A Made in Green label expires after one year, and manufacturers need to apply for renewal of the label. 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. Eco Passport by Oeko-Tex Eco Passport by Oeko-Tex is a certification system for textile chemicals (e.g. colourants, optical brighteners, antistatic agents, adhesives, cleaning agents). It was introduced in 2016. Chemicals awarded the Eco Passport label meet the requirements for sustainable textile production. The certification process comprises two stages: Screening: Manufacturer's disclosures about product ingredients are screened for chemicals that are listed in the European Union REACh regulation's SVHC (substances of very high concern) list or in the Oeko-Tex lists of chemicals with restricted use in textile products (RSL, restricted substance list) – specified in the Standard 100 – and
