From 1 February 2027, chemical formulators can begin recertifying relevant formulations through ZDHC Approved Certifiers - MRSL that have obtained approval for V4.0.

ZDHC will publish the list of approved V4.0 certifiers from this date.

Before agreeing on certification timelines with customers, formulators should confirm that their certifier is approved for V4.0 and can complete the assessment within the required timeframe.
