Brands and vendors should:

• Review and update their chemical management commitments, policies and supplier requirements to reference ZDHC MRSL V4.0 or the latest version.
• Communicate the implementation timeline and expectations to suppliers and business partners.
• Encourage supplier participation in ZDHC webinars and training.
• Establish implementation targets aligned with ZDHC's transition milestones.
• Designate a contact for supplier questions.

Brands should align their requirements with the ZDHC implementation approach to avoid additional or conflicting expectations.
