Assessments

Logo of the Inventory Multi-tiered Assessment and Prioritisation (IMAP) framework

NICNAS established the Inventory Multi-tiered Assessment and Prioritisation (IMAP) framework to accelerate the assessment of existing chemicals on the Australian Inventory of Chemical Substances (AICS or the Inventory).

IMAP is a scientific and risk-based model for assessing chemicals with three tiers of assessment. The assessment effort increases with each tier. A decision is made at the end of each assessment tier if the next tier of assessment is required to determine risk.

The risk assessments for human health and environment have been conducted separately and may have different outcomes and be published separately. The assessment outcomes are based on the information available at the time.

Chemicals assessed using the IMAP framework have been published in several tranches.

IMAP Tranche Publication and Public Comment Dates for published Tranches can be found here.


Tranche 24 assessments

Tranche 24 assessments were published on 29 June 2018 and are open for public comment until 24 August 2018.

As well as our regular assessments, we've updated our low concern polymers list. As these are low risk chemicals, they are of low priority to assess. By identifying them, we can concentrate our efforts on higher risk chemicals.

We've also updated our excluded use chemicals list. These are chemicals only being used, or suspected of only being used, in applications that aren't “industrial”. For example, therapeutic, agricultural, veterinary or food use. This work will help identify higher risk industrial chemicals that we need to assess.
