Request a Demo
AICIS recently issued a notice to request relevant introducers (manufacturers or importers) to submit the post-introduction declaration (PID) by 30 November 2025, if their chemical introduction (manufacture or import) is in the “Excepted” category and the first introduction was between 1 September 2024 and 31 August 2025.
Under AICIS, if the chemical is not on the Australian Inventory of Industrial Chemicals (AIIC), the introduction of this chemical shall be categorized before starting relevant activities. For the following chemicals, their introduction will fall under the Exempted category:
polymer of low concern;
low-concern biological polymer; or
chemical categorized as very low risk for human health and the environment.
Post-introduction declaration (PID) is a one-off declaration only for Exempted introductions. Introducers shall submit a separate PID for each very low-risk chemical they introduced for the first time during the AICIS registration year (1 September ~ 31 August) to demonstrate that these chemical introductions are very low risk. PID only applies to the first-time introduction; after that, introducers will no longer need to submit another PID for the same chemical introduction. Notably, introducers only need to submit one PID regardless of how many new low-concern polymers or low-concern biopolymers are introduced in a registration year.
Below is the example provided by AICIS for better illustration.
Example:
You introduced 2 chemicals for the first time in the exempted category during 2024-25 – one a polymer of low concern (PLC) and the other an introduction categorised as very low risk for human health and the environment. This means you’ll need to submit 2 separate declarations, one for each introduction.
