OEKO-TEX® ECO PASSPORT is an independent, multi-stage testing and certification system for chemicals, colourants and auxiliaries used to manufacture textiles and leather. The process verifies that chemical products and their ingredients meet specific requirements for safety, sustainability and regulatory compliance.

The ECO PASSPORT Restricted Substance List (RSL) combines substances restricted through ECO PASSPORT, STANDARD 100, LEATHER STANDARD and STeP, integrating seamlessly with downstream OEKO-TEX® certifications.

Further specifications

ECO PASSPORT certification involves a multi-stage procedure to assess whether each individual substance in a chemical product is not harmful to human health and that it meets statutory requirements. The first two stages are mandatory to receive a certificate. Stage three is currently optional.

  1. CAS Number Screening:
    During the CAS number screening, we compare the product components declared by the applicant against the list of harmful chemicals for the ECO PASSPORT (RSL/MRSL) and SVHC Candidate List from REACH.
  2. Analytical Testing:
    Analytical verification in our labs ensures that the certified chemicals can be used in the sustainable production of textiles and leather articles that are safe for human ecology.
  3. Self-Assessment & On-Site Visit (optional):
    An on-site audit (optional) verifies the data submitted by the manufacturer as part of a self-assessment (mandatory) at facility level. Applicants must have systems in place for environmental management, health and safety, quality management and social responsibility.

      ZDHC conformance

      • Completion of the CAS number screening and the analytical verification leads to ZDHC Conformance Level 1.
      • Together with the mandatory self-assessment, the on-site audit qualifies for ZDHC compliance level 2. If requirements regarding chemical hazard assessment capability are also met, level 3 is also possible.

      ECO PASSPORT vs. ZDHC Chemicals to Zero Progressive Level (CtZ-P)

      OEKO-TEX® ECO PASSPORT has been approved as a third-party certification for the ZDHC Chemical to Zero Progressive Level (CtZ-P) and thus fulfils the highest requirements for ZDHC conformity.

      ZDHC recently launched its CtZ-Progressive transitional phase. The CtZ-Progressive transitional phase requires that the formulation is certified for the ZDHC MRSL V3.1 Level 2 or 3 conformance.

      ECO PASSPORT certified products will be assigned to the CtZ-Progressive level in the ZDHC Gateway subject to a self-declaration by the formulator.

      How can ECO PASSPORT support you?

      Chemical industry

      ECO PASSPORT certification is a reliable third-party assessment of your chemicals that helps you market your products when it comes to communicating your product stewardship and sustainable practices. 

      Textile / leather industries

      The ECO PASSPORT certification assists you in the selection of chemicals that are environmentally friendly and harmless in terms of human ecology. You have reliable control over the substances used, right from their procurement, even before you feed them into your production process.

      Basic facts


      An ECO PASSPORT certificate is valid for one year and can be renewed up to three months before it expires. 

      By signing the declaration of conformity in the application, the applicant authorises the OEKO-TEX® Association to perform control tests on its certified products during the period that certificate is valid. You can apply to renew the certificate up to three months before it expires.

      Target group

      Any manufacturer of textile or leather chemicals can apply for an ECO PASSPORT certificate. ECO PASSPORT is suitable for all chemical products (chemicals, colourants and auxiliaries) - and their formulations - that are used in the textile, leather, apparel, footwear, home textiles or similar sectors.

      Wholesalers and resellers of chemicals can also apply for an ECO PASSPORT certificate in their own name for products already covered by the chemical manufacturer's certificate if no additional changes to the composition have been made.

      If no manufacturer's certificate is available, it is possible for distributors and retailers to apply for a limited certification. This temporary certification may only be renewed once for a maximum certificate validity of two years total. (Annual certificate renewal for chemical manufacturers is not limited.)

      Criteria / Requirements

      ECO PASSPORT certification combines requirements for harmful substances from all other OEKO-TEX® services (e.g. STANDARD 100 RSL and STeP MRSL) with statutory requirements. The ECO PASSPORT RSL is updated annually, based on newest scientific findings, legal requirements and market developments.

      Certification process

      • Application
        The applicant completes the application form and submits data on the chemicals used.
      • Self assessment
        The applicant submits data about the existing manufacturing conditions in form of a self-assessment questionnaire.
      • RSL / MRSL check
        We carry out a CAS number comparison of the indicated substances.
      • Analytical verification
        We analyse the chemicals in our labs.
      • On-site visit (optional)
        We carry out a company visit to check the applicant's provided data on facility level.
      • Issue of certificate
        We issue all relevant reports and the ECO PASSPORT certificate for you.
