In daily life, we are increasingly inseparable from electronic products. There are differences between EU RoHS and China RoHS in terms of control scope, controlled substances, regulatory systems, certification, self declaration, labeling requirements, testing institutions, testing methods, and public disclosure requirements. The EU's RoHS mainly focuses on the circulation sector, while China's RoHS has also strengthened regulation in the production process. The two are also different in terms of controlled substances, with fewer RoHS controlled substances in China. View >>
