ECO PASSPORT screens, tests and certifies chemicals before they enter the textile and leather supply chains. It protects workers, the environment and end consumers from harmful substances.

What toxic substances does ECO PASSPORT restrict?

(Restricted Substances)

OEKO-TEX® ECO PASSPORT bans or restricts substances that are harmful to human and environmental health. The restricted substance list (RSL/MRSL) is based on scientific data, global regulations and production methods.

What kinds of chemicals can be certified?

(Chemical Types)

Any chemicals, colorants, auxiliaries and formulations used for the production of textiles and leather can be certified with ECO PASSPORT.

  • Auxiliaries
    • Fiber, yarn, fabric, foam, rubber production
    • Dyeing and printing
    • Acids, bases, salts, solvents
    • Antifoam/slip, leveling
    • Defoamer/stabilizer
    • Penetrator
    • Rheology modifier
    • Water/effluent treatments
    • Technical auxiliaries (wetting, anti-foaming, detergents, dispersing, emulsifying, spotting, chelating, stabilizer agents)
  • Processing assistants (beamhouse, degreasing, tanning, retanning)
  • Colorants
    • Dyes (acid, basic, disperse, direct, reactive, azoic, vat, sulphur, natural, metal)
    • Pigments (inorganic, organic, metal, complex)
    • Printing pastes, inks (with/without colorants)
    • Solvent based finishing
  • Finishing assistants/agents
  • Coating agents/additives (solvent/aqueous/plastisol based)
  • Fatliquors and oils
  • Adhesives
  • Approved flame retardants and antimicrobials
  • Cleaning agents (drycleaning, aqueous, inorganic, degreasing)
  • Masterbatches
  • Synthetic resins/pellets

Who can apply for an ECO PASSPORT certificate?

(Company Types)
  • Any manufacturer of textile or leather chemicals can apply for ECO PASSPORT certification. ECO PASSPORT is suitable for all chemical products (chemicals, colorants 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 a certificate in their own name for products already covered by the chemical manufacturer's certificate and 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)

How does OEKO-TEX® ECO PASSPORT certify chemicals?

(Process and Feedback Loop)
  1. RSL/MRSL Check
    Transparent process to screen for chemicals of concern via cost-effective CAS number comparison - Chemical ingredients are compared with the OEKO-TEX® list of harmful chemicals (~1500 chemicals we are striving to keep out of the supply chain).
  2. Analytical Testing
    Analytical verification in our labs to ensure chemicals can be used for the sustainable production of textile or leather products that are safe for human ecology. (Formulations are certified at the minimal level with the option to continue to higher levels)
  3. On-Site Visit (Optional)
    Control at chemical supplier facility to check product stewardship system (for ZDHC Level 2/Chemical to Zero Progressive level (CtZ-P))
    - plus add optional hazard assessment questions (for ZDHC Level 3/Chemical to Zero Progressive level (CtZ-P))

What are the options for ZDHC integration?

(3 Options + ZDHC)

All options come with listing in the OEKO-TEX® Buying Guide and use of the OEKO-TEX® ECO PASSPORT product label.

Option 1 allows ZDHC Gateway listing at level 1.

Option 2 adds a product stewardship on-site visit and qualifies for ZDHC Gateway listing at level 2 and the ZDHC Chemical to Zero Progressive level (CtZ-P).

Option 3 adds a chemical hazard assessment questions to the on-site visit and qualifies for ZDHC Gateway listing at level 3 and the ZDHC Chemical to Zero Progressive level (CtZ-P).

How much disclosure is required?

(Confidential Disclosure)

Protecting confidentiality while reducing fees:

We recognize that chemical formulations and bills of substances (BoS) are highly guarded intellectual property. The information provided is encrypted and stored by the certifying institute and OEKO-TEX®. No recipes are publicly shared anywhere.

  • 100% disclosure of your formulation is not mandatory
    • The more you can disclose about your formulation, the easier the process of certification
    • Greater disclosure reduces your testing costs
  • Confidentiality is built into the system, but we are happy to sign an additional non-disclosure agreement (NDA)
  • To protect the lab teams during handling, OEKO-TEX® requires the disclosure of all constituent substances and known contaminants/by-products that are regulated by OEKO-TEX® or classified as hazardous by GHS or article 57 of the REACH regulation 1907/2006

Disclosure Level Options - Disclose more, test less:

With higher disclosure levels, testing effort, time and costs for the analytical verification stage are reduced.

Why is analytical verification required?


Disclosed does not always match reality. Testing ensures the certified chemicals do not contain unwanted impurities and side products (incorrect solvents, metals, surfactants, etc.).

How are the testing results rated?

(Certification Thresholds)

Threshold values are published in the ECO PASSPORT standard.

  • Substances 'certified without restrictions' fulfill the requirements of downstream certifications, such as STANDARD 100 and LEATHER STANDARD. Only products 'certified with no restrictions' are eligible for listing in the ZDHC Gateway
  • Any substances that are 'certified with restrictions' are mentioned on the ECO PASSPORT certificate so that they can be tested again during a downstream certification process

What is ECO PASSPORT product stewardship?

(On-site Visit)

The on-site visit verifies that the manufacturer has systems in place for environmental management, health and safety, quality management and social responsibility. It is currently optional for OEKO-TEX® ECO PASSPORT but required for ZDHC Levels 2 and 3.

Product stewardship checks:

  • Certificates for environmental management system
  • Documentation on wastewater treatment and waste handling
  • Commitments to worker health and safety (training records)

How long is an ECO PASSPORT certificate valid?


An ECO PASSPORT certificate is valid for one year. Certificate owners may apply to renew the certificate up to three months before it expires.

How can the ECO PASSPORT certification and label be used?

(Certificate & Label)

An OEKO-TEX® ECO PASSPORT certificate and label are awarded only when all the chemical products meet the test criteria.

The product label can be used for marketing communications specific to the certified chemical.

Since the label is a protected trademark, all companies using the label must comply with the labeling rules. Forgery and misuse of the trademark can be prosecuted under criminal and civil law.

The label and claim are NOT intended for identifying certified ingredients of another product. For example, this type of statement is not allowed: "the chemicals in this [fabric] are ECO PASSPORT certified".

For purchasing, the label is not sufficient proof of successful testing. Buyers should always require the supplier to submit a valid OEKO-TEX® certificate. The details on the ECO PASSPORT label (test number and test institute) must correspond to those on the certificate and the product must be included in the certificate scope.

Please view the labeling guide and contact us with questions.

How much does ECO PASSPORT certification cost?

(Pricing Structure)

ECO PASSPORT certification fees are made up of:

  • License fee - fixed - annual
  • Company audit fee - for levels 2/3 - fixed - 1st year, then every 3 years
  • Testing fees - variable - annual
    • Fees are based on the testing expenses for the specific chemical product(s) and groupings
    • Contact us for a quote based on required testing

How does ECO PASSPORT work within OEKO-TEX®?

(Modular System)

ECO PASSPORT is perfectly aligned with the modular OEKO-TEX® System. Chemicals, colorants and auxiliaries that are OEKO-TEX® ECO PASSPORT certified are also recognized by STANDARD 100 and LEATHER STANDARD, for the MADE IN GREEN label and as part of STeP facility certification.

Can biocides or flame retardant ingredients be certified?

(Active Chemical Products - ACPs)

Biologically active biocides and flame retardant substances must be approved on the OEKO-TEX® Active Chemical Products list prior to being used in products with any OEKO-TEX® certification.

Contact us to start the approval process.

How does OEKO-TEX® ensure consistent quality?

(Quality Assurance)

In addition to internal quality assurance programs, the certified company agrees to the declaration of conformity during application. This agreement allows OEKO-TEX® institutes to conduct control tests.

Each year, Hohenstein control tests at least 25% of certified products. Previously certified materials are re-tested during certification processes for downstream products. Random samples of OEKO-TEX® certified products are purchased from stores and tested again in the laboratory. In addition, independent auditors commissioned by OEKO-TEX® conduct unannounced site inspections to assess on-site quality assurance in the facilities.
