The Members of the European Union’s (“EU”) Environment Committee (“MEPs”) recently voted in favor of proposed amendments to the EU’s Restriction of Hazardous Substances Directive, first passed in 2002, banning the use of nanosilver and long multi-walled carbon nanotubes in electrical and electronic products. The legislators also approved language requiring that any electrical or electronic materials containing nanomaterials should be labeled as such and that manufacturers who use nanomaterials would be required to provide the European Commission with safety data on any materials used. Commentators have noted that the MEPs’ definition of nanomaterials is unclear and the current interpretation could require labeling for every electronic product, such as every transistor in a computer chip. A vote on the proposal is expected in October.
