REACH regulates chemical substances and includes, among other things, obligations for information, notification, authorization, and restriction. For articles, the SVHC candidate list and the restrictions under Annex XVII are particularly relevant. Compliance with the respective applicable requirements can be assessed and documented on the basis of suitable supplier, material, and product information.
RoHS by contrast specifically restricts certain hazardous substances in electrical and electronic equipment and, for the products covered, is part of the CE conformity assessment. Manufacturers must demonstrate that the applicable substance restrictions are complied with, taking into account any applicable exemptions.
