No, they are not. There are fundamental differences between REACH and ROHS. ROHS, standing for Restriction of Hazardous Substances, is an EU directive on certain substances which are present in electronic products. REACH, on the other hand, is an EU regulation laying down registration obligations to all chemicals which are present in a product in quantities of one tonne or more per annum. Generally, if a product is ROHS-compliant, the product still must fulfill REACH registration obligations before being placed into the market, if such product falls into the scope of REACH.
