RoHS certification signifies a product's compliance with the Restriction of Hazardous Substances Directive, established by the European Union in 2003. This directive restricts the use of specific hazardous materials found in electrical and electronic products. All applicable products in the EU market after July 1, 2006, must pass RoHS compliance. The certification ensures the product is free from substances like lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers. RoHS certification contributes to environmental protection and consumer safety by minimising the release of these substances into the environment.
