The Australian Industrial Chemicals Introduction Scheme (AICIS) will replace NICNAS on 1 July 2020 as the new national regulator of the importation and manufacture of industrial chemicals in Australia.
Anyone who imports or manufactures industrial chemicals into Australia for commercial purposes must register their business with AICIS and pay a fee as well as categorise each chemical importation or manufacture.
Take a look into AICIS a bit further here.
