The ECO PASSPORT by OEKO-TEX® is the comprehensive verification and certification system for textile chemicals, colourants and auxiliaries.

The ECO PASSPORT textile chemical verification system is fully integrated and harmonized with the two OEKO-TEX® certification systems for sustainable textile production ( STeP by OEKO-TEX® ) and product safety ( STANDARD 100 by OEKO-TEX ).


The development of the ECO PASSPORT by OEKO-TEX® creates a standardised test and certification system for textile chemicals, colourants and auxiliaries. Following the integration of the ECO PASSPORT into the OEKO-TEX® system, a new section called "Textile chemicals" has been added to the OEKO-TEX® Buying Guide. This means that suppliers can now publicise their chemicals suitable for sustainable textile production here.

The service has been developed for:

  • Manufacturers of textile chemicals
  • Manufacturers of textile products right along the supply chain
  • Wholesalers in textile chemicals
  • Sourcing offices
  • Textile buyers for brands and retailers


  • The ECO PASSPORT by OEKO-TEX® certification process consists of two stages:
    • Stage I: Compliance screening
      Chemicals are screended at the ingredient level against the OEKO-TEX® Restricted Substances List (RSL) and the Manufacturing Restricted Substances List (MRSL).
    • Stage II: Analytical verification
      Analytical verification in our OEKO-TEX® laboratories to ensure that certified products can be used in the sustainable production of human-ecologically optimized textiles.
  • The report from the RSL testing confirms compliance with the REACH regulation as well as with the OEKO-TEX® RSL and MRSL. The name and category of the certified products are shown on the certificate.
  • The ECO PASSPORT correlates perfectly with the existing OEKO-TEX® certification systems for sustainable textile production ( STeP by OEKOTEX® ) and product safety ( STANDARD 100 by OEKO-TEX ).
  • Consequently, chemicals, colourants and auxiliaries that are endorsed with the ECO PASSPORT by OEKO-TEX® are also approved under the STANDARD 100 by OEKO-TEX and the STeP by OEKO-TEX® monitoring process.

Benefits for manufacturers, brands and retailers:

  • Compliance with the ECO PASSPORT standard means that products also comply with industry initiatives such as ZDHC (Zero Discharge Hazardous Chemicals) and with the legal requirements.
  • Certification by an independent third party firstly protects confidential product data and, secondly, provides the transparency about ingredients that the market demands.
  • Because the system is divided into two stages, any required improvements can be made after the first stage, thereby avoiding unnecessary expenditure on analysis.
  • The OEKO-TEX® Buying Guide allows brands, retailers and manufacturers to source sustainable and safer chemical products for their textile production.
  • Chemical producers have the chance to offer their OEKO-TEX® compliant chemicals to the over 10,000 OEKO-TEX® certificate holders via the OEKO-TEX® Buying Guide.

Requirement for test samples:

  • For the analytical testing, a representative sample of the chemical, colourant or auxiliary is required (about 50 g, packed separately, with the production date and batch number). You will be given more information in the course of the application process.
  • The total processing time for the certification process depends on the complexity of the particular chemical product, but is normally about 2 – 3 weeks after receipt of all the samples and documentation.

Certificate information:

  • The certificate is valid for 1 year. An extension can be applied for no earlier than three months before the end of its period of validity.
  • By signing the declaration of conformity, the customer agrees that the OEKO-TEX® Association is entitled to carry out random testing of their certified products during the period of validity of the certificate.

ZDHC & Detox Conformity

The MRSL (Manufacturing Restricted Substances List) for chemicals published by the industry initiative ZDHC (Zero Discharge of Hazardous Chemicals) is already integrated in the various OEKO-TEX® system components such as the ECO PASSPORT by OEKO-TEX®.

With the ECO PASSPORT by OEKO-TEX® certification Hohenstein confirms the ZDHC conformity of tested textile chemicals, colorants and auxiliaries for textile production. With the ECO PASSPORT you can already take a major step towards achieving the ambitious goals of the Greenpeace DETOX campaign by 2020.
