ZDHC InCheck Reporting comprises of a self-assessed Performance InCheck Report and verification option.

The Performance InCheck asks suppliers to digitise their chemical inventory list (CIL) and report it to receive feedback on the CIL's ZDHC MRSL conformance and Chemicals to Zero performance. Suppliers can report either on "delivery of chemicals" or "usage of chemicals" CIL types and should do this consistently, ideally on a monthly basis. Attention: certain types of chemicals (e.g. commodity chemicals) are exempted from InCheck reporting, despite being in-scope of the ZDHC MRSL.

To see full details of requirements, please see the InCheck Reporting Chapter on the Suppliers Roadmap to Zero.
