Australia’s National Industrial Notification and Assessment Scheme (NICNAS) recently issued guidance on the new chemical requirements for the notification and assessment of industrial nanomaterials that are considered to be new chemicals. The new administrative arrangements will be effective from January 1, 2011, and will apply to any new chemical that falls under the following working definition of “industrial nanomaterial”:

. . . industrial materials intentionally produced, manufactured or engineered to have unique properties or specific composition at the nanoscale, that is a size range typically between 1 [nanometer (nm)] and 100 nm, and is either a nano-object (i.e. that is confined in one, two, or three dimensions at the nanoscale) or is nanostructured (i.e. having an internal or surface structure at the nanoscale).
