Updates to AIIC in 2025 can be accessed here.

Background
AIIC serves as a searchable database containing approximately 40,000 chemicals that are manufactured or imported for industrial use in Australia. Industrial chemicals covered by assessment certificates are listed on the AIIC after 5 years, but there are also provisions for early listing. Any registered person can introduce an industrial chemical listed on the Inventory but must comply with the terms of the Inventory listing, along with record-keeping and reporting requirements.
The introductions (manufacture or import) of chemicals that are not listed in AIIC should be categorized before starting relevant activities. Under the Australian Industrial Chemicals Introduction Scheme (AICIS), for different introduction categories, different obligations apply.
