Companies must provide a name for the nanoforms or sets of nanoforms of their substance when registering nanomaterials under the REACH Regulation. This will enable registrants and authorities to unambiguously refer to registered nanoforms in regulatory documents, such as decisions and safety data sheets.

The change will take effect on the 2^nd of November 2020 following the next release of IUCLID. Companies that have already registered their nanoforms do not need to take any immediate action but will be required to provide a name in the next update of their registration dossier.

A new registration manual will be available in October with advice on preparing registration dossiers that cover nanoforms.
