Manufacturing Restricted Substances List (MRSL) & Conformity Guidance

The ZDHC MRSL V1.1 is a list of chemical substances banned from intentional use in facilities that process textile materials and trim parts in apparel and footwear. The MRSL establishes acceptable concentration limits for substances in chemical formulations used within manufacturing facilities.

The limits are designed to eliminate the possibility of intentional use of listed substances. The intent of the MRSL is to manage the input of chemicals to the suppliers and remove those hazardous substances from the manufacturing process. It is a living document and will be updated as needed to expand the materials and processes covered and to add substances that should be phased out of the value chain. 

On an ongoing basis, we will publish the results of studies undertaken as part of this initiative. Documents listed below will be updated as soon as new information becomes available. 

ZDHC Acceptance of Certification Standard and Testing Laboratory for ZDHC MRSL Conformance

To accelerate the global impact of the ZDHC Roadmap to Zero Programme we have decided in a very early stage not to start our own certification system for ZDHC Manufacturing Restricted Substances List (MRSL) conformant chemistry but instead to leverage existing certification as indicators of ZDHC MRSL conformance.

If you are interested in becoming one of the ZDHC Accepted Certification Standards or Testing Laboratories (for analytical test report level 1 conformance), please submit your application through completing the online form below.
