New Industrial Chemical Added to the Australian Inventory After Five Years

On 20 October 2025, the Australian Industrial Chemicals Introduction Scheme (AICIS) announced the addition of a new industrial chemical to the Australian Inventory of Industrial Chemicals (Inventory) in accordance with section 82 of the Industrial Chemicals Act 2019. The chemical, Nonadecane, 9-methylene-, mixed with 1-decene, dimers and trimers, hydrogenated (CAS 1000172-32-6), has been listed following the completion of the five-year period since its assessment certificate was issued. The listing date is 16 October 2025. Companies introducing this substance must comply with ongoing information obligations—they are required to notify AICIS within 28 days if their manufacturing or importation circumstances differ from those described in the original assessment. This update ensures transparency and continued regulatory oversight under Australia’s national framework for the safe introduction of industrial chemicals.
