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.

¿Qué sustancias tóxicas restringe ECO PASSPORT?

(Sustancias restringidas)

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.

¿Quién puede solicitar un certificado ECO PASSPORT?

(Tipos de empresa)
  • 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)

¿Cómo certifica OEKO-TEX® ECO PASSPORT los productos químicos?

(Proceso y circuito de retroalimentación)
  1. Comprobación RSL/MRSL
    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. Pruebas analíticas
    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. Autoevaluación
    Review of the chemical manufacturer's responsible systems relating to environmental & quality management, health & safety, social responsibility
  4. Visita in situ (Opcional)
    Control at chemical supplier facility to check product stewardship system (para ZDHC Nivel 2)
    - Preguntas opcionales de evaluación de riesgos (para ZDHC Nivel 3)

¿Cuáles son las opciones para la integración ZDHC?

(3 opciones + 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.

Option 3 adds a chemical hazard assessment questions to the on-site visit and qualifies for ZDHC Gateway listing at level 3.

¿Cuánta divulgación se requiere?

(Divulgación confidencial)

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.

¿Por qué se requiere la verificación analítica?


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

¿Cómo se califican los resultados de las pruebas?

(Umbrales de certificación)

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

¿Qué es la gestión del producto ECO PASSPORT?

(Visitas in situ)

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)

¿Cuánto tiempo es válido un certificado ECO PASSPORT?


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

¿Cómo se puede utilizar la certificación y la etiqueta ECO PASSPORT?

(Certificado y etiqueta)

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.

¿Se pueden certificar biocidas o ingredientes retardantes de llama?

(Productos químicos activos - "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.

¿Cómo garantiza OEKO-TEX® una calidad constante?

(Garantía de calidad)

Además de los programas internos de garantía de calidad, la empresa certificada acepta la declaración de conformidad durante la solicitud. Este acuerdo permite a los institutos OEKO-TEX® realizar pruebas de control.

Cada año, Hohenstein realiza pruebas de control en al menos el 25% de los productos certificados. Los materiales previamente certificados se vuelven a probar durante los procesos de certificación de los productos posteriores. Muestras aleatorias de productos certificados OEKO-TEX® se compran en las tiendas y se vuelven a probar en el laboratorio. Además, auditores independientes encargados por OEKO-TEX® realizan inspecciones in situ sin previo aviso para evaluar la garantía de calidad in situ en las instalaciones.
