Declaration Letter of REACH & RoHS Compliance
About REACH In June 2007, the European Union Regulation (EC) 1907/2006 concerning the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) was first released. Under this Regulation, manufacturers are required to gather information on the properties of their chemical substances, which will allow their safe handling, and to register the information to European Chemicals Agency (ECHA). The aim is to improve the protection of human health and the environment through the better and earlier identification of the intrinsic properties of chemical substances.
About RoHS RoHS Directive (EU Directive 2002/95/EC ) was issued in 2002, restricted the use of the six chemicals lead, cadmium, mercury, and hexavalent chromium, as well as flame retardants polybrominated biphenyls (PBBs) and polybrominated dipheny ethers (PBDEs).
