What is IMAP?

NICNAS established the Inventory Multi-tiered Assessment and Prioritisation (IMAP) framework to accelerate the assessment of chemicals listed on the Australian Inventory of Chemical Substances (AICS). For more information on the IMAP Framework download Inventory Multi-tiered Assessment and Prioritisation (IMAP) Framework [WORD 855KB].

The objectives of IMAP are to:

  • identify and rapidly assess existing chemicals of concern, and
  • support the risk management of industrial chemicals in Australia by enhancing the flow of chemical safety information.

IMAP arose from recommendations of an independent review of the NICNAS Existing Chemicals Program and a subsequent research report by the Productivity Commission.

The IMAP framework was developed in consultation with stakeholders and technical experts and is a science and risk based framework for the assessment and prioritisation of chemicals on the AICS.

The IMAP framework provides a more flexible and transparent approach to prioritising the large number of chemicals on the AICS for assessment in a way that is responsive to the needs of industry (including workers), community and government.


The IMAP framework is being implemented in stages. Read more about the process that was used to identify Stage One chemicals.

We began the assessment of Stage One chemicals in July 2012.

Stage One of IMAP ended in 2016. The IMAP Review 2016 is informing the development of the future framework for the assessment and prioritisation of the remainder of the chemicals on the AICS.

Stage Two of IMAP began in July 2016. We will continue to assess chemicals on the AICS, including:

  • Chemicals identified as a concern for which action has been taken overseas
  • Chemicals that can be rapidly identified and assessed by using Stage One information.

We will also publish information for chemicals on the AICS that pose a low risk to human health or the environment or both. This work will provide efficiencies for the identification of higher risk chemicals requiring assessment.
