RoHS certification is the European Union's directive on the restriction of hazardous substances in electrical and electronic equipment, which requires the restriction of the use of six hazardous substances such as lead, mercury and cadmium. Products need to comply with the European standards, otherwise they will be banned from importing.RoHS certification covers a wide range of products, including household appliances, IT and communication products. The certification process requires the preparation of samples, application forms, product specifications, etc., without the need for annual factory inspections. The new directive expands the scope of products to include medical devices and industrial monitoring equipment, while requiring manufacturers and importers to meet the directive's requirements and pass on relevant information.
