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).

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.

Tranche 20

Tranche 20 assessments were published on 10 March 2017. Public comments were open until 12 May 2017.
