RoHS Directive

What is the RoHS Directive?

The RoHS Directive, the European Union legislation referenced in the California statutes on toxics in lighting, restricts the use of six hazardous substances in the manufacture of electrical and electronic equipment (EEE). The term EEE includes lighting equipment (as defined in Directive 2002/96/EC Annex IA and IB) and electric light bulbs and luminaries in households. (2002/95/ EC and EU Commission Decision 2005/618/EC).

The RoHS Directive restricts EEE containing lead, mercury, hexavalent chromium, cadmium, PBBs and PBDEs in amounts exceeding a maximum concentration value (MCV) from being put on the market. MCVs are set as follows by the RoHS Directive:

Hazardous Substance

MCV (% by weight) inhomogeneous materials


0.1 % (1000 ppm)


0.1 % (1000 ppm)

Hexavalent chromium

0.1 % (1000 ppm)


0.1 % (1000 ppm)


0.1 % (1000 ppm)


0.01 % (100 ppm)

The RoHS Directive exempts certain applications of lead, mercury, cadmium and hexavalent chromium from these limits and in some cases establishes alternative limits.
