During the formulation recertification period, InCheck will display V3.1 and V4.0 conformance information side by side.
On 1 June 2028 the supply chain implementation period ends, and the transition to ZDHC MRSL V4.0 conformant formulations and substances should be completed. Formulations certified only against V3.1 will be archived and unpublished on the ZDHC Gateway. Any formulation used that is not ZDHC MRSL V4.0 certified and is not available in the ZDHC Gateway will be identified as non-conformant in Performance InCheck reports.
