The Restriction of the use of certain Hazardous Substances (RoHS) Directive restricts the producers of eight categories of electrical and electronic equipment from placing on the market products that contain six "banned" substances unless specific exemptions apply. These six substances are: Lead, Mercury, Hexavalent chromium, Cadmium, Polybrominated biphenyl flame retardants and Polybrominated diphenyl ether flame retardants.
The phrase 'banned' is misleading as you can have minute concentrations values but they are so small that it effectively prevents their use. The maximum concentration values (MCV) are 0.1 % by weight of lead, mercury, hexavalent chromium, PBB and PBDE and 0.01 % by weight cadmium in homogeneous materials.
