In close co-operation with the CARACAL subgroup on nanomaterials ("CASG Nano", composed of Member States and stakeholder experts) the Commission prepares advice on how to manage nanomaterials in accordance with REACH and the CLP Regulation. The first paper "Nanomaterials in REACH" provides an overview of how the provisions of REACH apply to nanomaterials. The second paper, Classification, Labelling and Packaging of Nanomaterials in REACH and CLP, focuses on the classification of nanomaterials in accordance with REACH and particularly the CLP Regulation. Additional papers are planned on registration, communication in the supply chain and substance identification. These papers can be considered as a preliminary advice and will be used by ECHA in their further work on relevant guidance documents in conjunction with the detailed RIPoN reports.
