The Input Focus Area relates to the tools and services that are the cornerstone of the ZDHC Roadmap to Zero Programme. These tools were created to change how clothing, apparel and footwear end consumer products are made by improving chemical inputs, rather than trying to eliminate hazardous outputs from effluents or the final products.

ZDHC tools include:

ZDHC Manufacturing Restricted Substances List (ZDHC MRSL)

The ZDHC Manufacturing Restricted Substances List (ZDHC MRSL) V1.1 is a list of chemical substances banned from intentional use in facilities that process textile materials, leather and trim parts in textiles, apparel and footwear. By using chemical formulations that conform to the ZDHC MRSL, suppliers can assure themselves, and their customers, that banned chemical substances are not intentionally used during production and manufacturing processes.

The ZDHC MRSL is electronically available at On this interactive, user-friendly platform, a user can easily search for chemical formulations that are restricted from intentional use, or download the ZDHC MRSL as a PDF file.

ZDHC MRSL Conformance Guidance

The ZDHC MRSL Conformance Guidance provides chemical suppliers with an indication system to assess the extent to which a chemical formulation conforms to, or meets, the requirements of the ZDHC MRSL. ZDHC’s intent is to leverage third-party certification systems to create an indication of conformance.  An integral part of the indication system takes the form of certificates from ZDHC accepted third-parties or acceptable analytical test results. It also describes the criteria that certification bodies must meet in order to be accepted by ZDHC as an indicator of MRSL conformance.

ZDHC MRSL Principles and Procedures

As the ZDHC MRSL is a living document, it is updated as needed to expand the materials and processes covered and to add substances that should be phased out of the value chain. This Principles and Procedures document contains and explains the process used to update the ZDHC MRSL. 

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 (ZDHC 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.
