Importers and manufacturers (introducers) of industrial chemicals for commercial purposes need to register their business under this scheme. All industrial chemical introducers must categorise their chemical importation or manufacture (introduction) into the following categories i.e., Listed introduction, exempted introduction, reported introduction, assessed introduction, commercial evaluation before placing into Australian territory.

If the introduction is listed in the Australian Inventory of Industrial Chemicals (the Inventory), then it is categorized as Listed introduction, and can be placed in the market in complying with the regulatory obligations (if any). If the introduction is not in the listed category, then it must be authorized into any one of the other categories.
