Confusion over classification of nanomaterials under the Reach chemicals legislation has led to two groups of companies using different criteria to submit data on carbon nanotubes to the European Chemicals Agency (ECHA).
Currently there is so much uncertainty about dealing with nanomaterials under the Reach regulations (which came into force in 2008) that different groups of companies are forming separate data-gathering bodies, called substance information exchange forums (SIEFs), to deal with carbon nanotubes (CNTs).
One group is setting up its own SIEF for carbon nanotubes to register them as distinct chemicals with their own safety profile. Another much larger collection of CNT producers and importers, including the multinationals Bayer MaterialScience and Arkema, are planning to register the nanomaterials as a form of bulk graphite so that they will not require their own registration dossier.
