Rayson is very concerned about environment protection issues; therefore, we acted assertively in that area. To comply with the regulations of Reduction of Hazardous Material (RoHS) and Waste Electrical and Electronic Equipment (WEEE), Rayson has started to test raw material management and lead-free manufacturing process since 2003.
