Collaboration is a key success factor when implementing the ZDHC MRSL. We’ve identified four key stakeholder types that play a key role: Certification Bodies, “Chemical” Formulators, Facilities/Suppliers, and Brands/Retailers. By implementing in a collaborative, connected way, these stakeholders can reduce the impact of the implementation efforts. The ZDHC MRSL Industry Standard Implementation Approach explains what is expected of each stakeholder in the transition period from one MRSL version to the next.

It is the time period in which both the old and new versions of the ZDHC MRSL are available. This allows the chemical industry to align with the latest version of the ZDHC MRSL and make any necessary changes to chemical products, stock, or certifications.

A change log is provided in the e-MRSL, which describes the differences.

The main responsibilities of brands are:

• Communicating the adoption of the ZDHC MRSL V2.0 to its supply chain
• Requiring their Suppliers to register all their used chemical formulations in the ZDHC Gateway

Formulators are responsible for the main part of the implementation of the ZDHC MRSL. These are the key steps for the Formulators:

1. Check for newly added substances to the ZDHC MRSL V2.0 (and Candidate List: optional)
2. Update/Replace - if newly added substances are present, update or replace the formulation(s)
3. Certify chemical products against the ZDHC MRSL V2.0 and upload on the ZDHC Gateway.

The main responsibilities of a Supplier are:

1. Communicate that it requires ZDHC MRSL V2.0 conformant chemical products
2. Check its chemical inventory certification status via the ZDHC InCheck Solution.
