The ZDHC Manufacturing Restricted Substances List (ZDHC MRSL) is a list of chemical substances banned from intentional use in textile, leather and footwear manufacturing (except metallic trims). Using chemical formulations that meet the requirements of (conform to) ZDHC MRSL allows suppliers to assure both their customers, and themselves, that banned chemical substances are not intentionally used during production and manufacturing processes.
