By the end of 2015, Tier II human health and/or environment assessments for 2482 chemicals had been completed and published. Tier II assessments provide more comprehensive chemical safety information than Tier I assessments and include information on: use; existing national or international restrictions; a summary of chemical identity information; physico-chemical properties; environmental fate; relevant (eco) toxicological data risk characterisation; advice to the public and industry; and recommendations for risk management. The Tier II assessments were found to be a valuable source of information for a range of stakeholders. The content was found to be fit for purpose with some minor modifications suggested (refer What we heard: enhancing chemical safety information). What we heard: enhancing chemical safety information The transition process from Tier I to Tier II, and to Tier III, is well-rationalised and transparent (on the NICNAS website). It is important to be about the status of an assessment where the human health and environment components have progressed at different rates and one is available before the other. Assessments have been published where the environment component was pending – this makes the chemical’s status uncertain. The assessment outcome isn’t determined until both components are complete. The information on the NICNAS site is useful core information. Consideration could be given to providing some additional information and periodic review. (...) suggests that there are more structured updates on the specific assessment of chemicals. Tier I assessments [Provision of information on low concern chemicals is valuable], because it contributes to the knowledge available on chemicals more broadly and can assist in future management actions, especially if alternate data becomes available at a later date.
