RoHS Directive, which was adopted on July, 1 2006 by EU,
is a kind of trade barrier which gives disadvantageous actions against those imported electrical and
electronic equipment that contains restricted hazardous substances (Pb, Cd, Hg, Cr+6, PBBs, and
PBDEs) in excess of allowed limits.

  • 8 equipment categories except medical devices and monitoring & control instruments out of
    electrical and electronic equipment up to 1000 V AC and 1500 V DC defined by WEEE.
    (large household appliances, small household appliances, IT & telecommunications equipment,
    consumer equipment, lighting equipment, electronic & electrical tools, toys, leisure,
    & sports equipment, and automatic dispensers)
  • After July 1, 2006, new electrical and electronic equipment that contain 6 specific hazardous
    substances (Pb, Cd, Hg, Cr+6, PBBs, and PBDEs) cannot be sold in the EU.
