Substances Included in RoHS

There are six original substances that each have a threshold based on weight. 

Substance RoHS Limit: MCV – Maximum Concentration Values:

  • Lead (Pb) < 0.10% = < 1,000 PPM
  • Mercury (Hg) < 0.10% = < 1,000 PPM
  • Hexavalent Chromium (Cr VI) < 0.10% = < 1,000 PPM
  • Cadmium (Cd) < 0.01% = < 100 PPM
  • Polybrominated Biphenyls (PBB) < 0.10% = < 1,000 PPM
  • Polybrominated Diphenyl Ethers (PBDE) < 0.10% = < 1,000 PPM

RoHS Directive (EU) 2015/863 (sometimes incorrectly referred to as "RoHS 3") adds four more substances:

  • Bis(2-Ethylhexyl) phthalate (DEHP):  < 0.10% = < 1,000 PPM 
  • Benzyl butyl phthalate (BBP):  < 0.10% = < 1,000 PPM
  • Dibutyl phthalate (DBP):  < 0.10% = < 1,000 PPM
  • Diisobutyl phthalate (DIBP):  < 0.10% = < 1,000 PPM
