Knowledge base
How do I know which conformance level a chemical product has?

Each registered chemical product has a ChemCheck Report. A ChemCheck Report is a ZDHC MRSL Conformity Certificate for formulators. It includes a chemical product summary, including the ZDHC MRSL Conformance Level, with a description of the respective level. For more information on ChemCheck, please check the Gateway section of the Knowledge Base.

What is the ZDHC Gateway - Chemical Module?

Chemical products covered by restrictions in the ZDHC MRSL include, but are not limited to, cleaners, adhesives, paints, inks, detergents, dyes, colourants, auxiliaries, coatings and finishing agents used during raw material production, wet processing, process machinery maintenance, wastewater treatment, sanitation, and pest control.ZDHC MRSL limits apply to substances in commercially available chemical products, not those from earlier stages of chemical synthesis

Does the ZDHC MRSL apply to a shoe finishing facility?

The ZDHC Gateway Chemical Module is the world's first database of safer chemistry for the entire value chain. This digital tool simplifies the search for alternatives. It provides an easy entryway to register and browse safer chemistry solutions.

Does “Registration” mean my chemical products conform to ZDHC MRSL requirements? (Formulators)

No. Chemical formulator and/or chemical product registration do not mean that the chemical products meet ZDHC MRSL requirements. It only means that they have provided information about the company and their chemical products. here.

How can Formulators upload a document that changes the conformance level in the ZDHC Gateway - Chemical Module?

The system automatically updates the conformance rating when a new qualifying document is uploaded, once it has gone through the verification process.For example, if a chemical manufacturer uploads an acceptable test report or an acceptable third-party certificate, the system will automatically change the rating of the chemical product from self certification.

What does a Formulator have to upload to the ZDHC Gateway - Chemical Module to prove ZDHC MRSL conformance?

Depending on the conformance level it may be a test report or third-party documentation review (Level 1), a Level 2 which includes a review of the chemical product and documentation review of the formulator’s chemical product stewardship or a Level 3 review which requires a supplier site visit as a part of the chemical product stewardship review. This is the standard approach but there may be some exceptions..
