In 2011, a group of major apparel, leather, and footwear brands and retailers made a shared commitment to reduce or substitute hazardous chemicals in their value chain and ensure safer handling of chemicals in the workplace for brands, the environment and workers.

Arising from this collaboration, The ZDHC Gateway – Chemical Module* is an advanced search engine for chemical formulations that conform to the ZDHC MRSL (according to ZDHC MRSL Conformance Guidance). It helps textile, apparel and leather manufacturers find safer alternatives and substitute hazardous chemicals in the production process.

ZDHC Accepted Certification Standards for ZDHC MRSL Conformance


It is our aim to accelerate the global impact of the ZDHC Roadmap to Zero Programme. To this end, rather than developing our own certification system for ZDHC MRSL conformant chemistry, we leverage existing certification as indicators of ZDHC MRSL conformance.

ZDHC Accepted Certification Standards and Testing Laboratories for ZDHC MRSL Conformance are listed on the ZDHC Gateway - Chemical Module. They are rated as conforming to ZDHC MRSL Conformance Guidance on levels ranging from 1 to 3. Formulations certified by these standards are directly verified and officially ranked within the ZDHC Gateway – Chemical Module.

Below is a list of the currently accepted certification standards and testing laboratories, and the level of formulation conformance they indicate:

The  ZDHC Accepted Certification Standards will help us tremendously to work towards our goal and support the industry by sourcing safer chemicals.

To become a ZDHC Accepted Certification Standard, interested organisations can apply here for acceptance of their Chemical Formulation certification system by the ZDHC Foundation.

To find out more about the accreditation process, please review the ZDHC MRSL Conformance Guidance.
