Core Viewpoint - The Ministry of Industry and Information Technology (MIIT) has introduced a mandatory national standard for limiting harmful substances in electrical and electronic products, aiming to enhance the green level and safety standards of these products, which are crucial for public health and environmental protection [1][2]. Group 1: Standard Overview - The new standard improves China's RoHS control system, establishing a governance framework that ensures standardized production, informed consumer choices, effective government regulation, and industry development [1][3]. - The standard includes three main components: limits on harmful substances, labeling requirements, and testing methods that align with international standards [3]. Group 2: Harmful Substance Management - The standard specifies limits for four heavy metals (lead, mercury, cadmium, hexavalent chromium) and six types of persistent organic pollutants, creating effective constraints for manufacturers [3][4]. - Products are categorized into two types: Type I includes frequently used consumer electronics that must meet strict limits and labeling requirements, while Type II includes other products that also require labeling but with less stringent controls [4]. Group 3: Implementation Timeline - The standard will have a two-year transition period, officially coming into effect on August 1, 2027, with an additional one-year grace period for existing inventory, allowing products produced or imported before the standard's implementation to be sold until August 1, 2028 [5].
