Do all existing formulations need to be reformulated?

No. Some formulations may remain conformant with ZDHC MRSL V4.0 without changes to their composition.

Formulations that remain compliant with the V4.0 substance requirements may retain their existing composition; however, their certification must be updated against V4.0 by a ZDHC Approved Certifier - MRSL authorised for V4.0 .

Formulations that cannot meet V4.0 requirements should be reformulated and replaced with suitable V4.0-certified alternatives, or withdrawn.
