What should I do to update my certification?

In case your chemical products are approved for the ZDHC MRSL, but the ZDHC MRSL need to be updated, please contact your ZDHC MRSL Accepted Certification Body to enquire about the process they will follow with you. During this time the certificate remains valid but the level of conformance on the ZDHC Gateway will drop to registered.

During the transition period, a formulator's valid certificate for the conformance of their chemical products could expire in, for example, early 2021. What process should they then follow? Will all current certificates become invalid?

During this time the certificate remains valid but the level of conformance on the ZDHC Gateway will drop to the ‘registered’ status.

Based on their validity period, my chemical product certifications only expire in late 2021 or in 2022. Do I have to recertify these chemical products before the relevant expiry dates?

Each Accepted Certification Body will contact their customers to inform them on what is needed to transition their certificates.

Do I have to retest new chemical products that are uploaded via third-party certification against the latest version of the ZDHC MRSL?

This depends on the chemical product and the process followed by the Accepted Certification Body. Please contact your Accepted Certification Body once they are accepted for the latest version.

How will a chemical product be differentiated as compliant amongst the different versions in the ZDHC Gateway - Chemical Module?

The version of compliance will be visible in the ZDHC Gateway and on the chemical product's ChemCheck report

After January 2021, can chemicals that are certified for ZDHC MRSL V1.1 or non-public Level 0 Gateway chemical products remain in the ZDHC Gateway?

If a chemical product is still active it will remain visible in the ZDHC Gateway but the status will be changed to 'registered'.

If my chemical product has a certification for ZDHC MRSL V1.1 and V2.0, what should I do on the ZDHC Gateway - Chemical Module?

Upload the certificates, the ZDHC Gateway will automatically display the latest version.
