The EU RoHS Directive (2011/65/EU)restricts the maximum allowable levels of lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr6+), polybrominatedbiphenyl (PBB) and polybrominated diphenyl ether (PBDE) flame retardants to0.1% or 1000 ppm (except for cadmium, which is limited to 0.01% or 100 ppm) byweight of homogeneous material in electrical equipment and electronic products.In order to manufacture these products within or import into the EuropeanUnion, manufacturers are responsible for providing due diligence documentation.

The restrict substances andlimits are shown as below:
