The HDD industry strives to improve its manufacturing processes and products so that materials of environmental concern are minimized or eliminated where feasible.  The industry has invested considerable time and resources to comply with the existing European Union (EU) Restriction on the Use of Hazardous Substances (RoHS) Directive while its full technical, social and cost implications are still being determined.

On 1 June 2007, REACH entered into force to streamline and improve the former legislative framework on chemicals of the European Union (EU), and REACH was established separately from RoHS.  This guideline is the proposed response to this newer regulation.
