The Swedish Chemicals Agency (KemI) published an April draft proposal to amend the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation to ensure the safe handling of nanomaterials. The draft proposal would adopt the October 2011 European Commission recommendation on the definition of nanomaterial. It would require manufacturers and importers of a nanomaterial, either on its own or in one or more mixture(s), in quantities of ten kg or more per year, to register. The obligation to register on-site isolated intermediates or transported intermediates that fulfill the definition of nanomaterials would apply to any manufacturer of the nanomaterial intermediate in quantities of ten kg or more per year. Producers or importers of articles containing nanomaterials would be required to notify the European Chemicals Agency if the nanomaterial is present in those articles in quantities over ten kg per producer or importer per year.
