RoHS restrictions

To protect human health and the environment, the EU RoHS and China RoHS directives demand the avoidance of six substances – heavy metals as well as brominated fire retardants and plasticisers.

The restrictions, or permissible highest concentrations in homogeneous materials, apply to the following substances:

Lead 0,1 %
Mercury 0,1 %
Cadmium 0,01 %
Hexavalent chromium 0,1 %
Polybrominated biphenyls (PBB) 0,1 %
Polybrominated diphenyl ethers 0,1 %


Where highest concentrations are exceeded due to technical requirements, these exceptions are defined in appendix III of the 2011/65/EU DIRECTIVE, such as, for example, copper alloys with a percentage by weight of up to 4 % lead (exception 6c).

These exceptions are not valid for the China RoHS. Exceeding the highest concentrations must be shown through the display of an orange-coloured marking and also a manufacturer’s declaration “Declaration of manufacturer according to China RoHS”.

The European Commission already has a continuation in the DIRECTIVE (EU) 2015/863 of 31 March 2015, which from 22 July 2021 restricts further substances (plasticisers) in their application.

Di(2-ethylexyl)phthalate (DEHP) 0,1 %
Butyl benzyl phthalate (BBP) 0,1 %
Dibutyl phthalate (DBP) 0,1 %
Diisobutyl phthalate (DIBP) 0,1 %
