About assessments

We assess industrial chemicals that are manufactured or imported into Australia. Our assessments cover the hazards and risks to human health and the environment from the importation or manufacture and use of chemicals in Australia. We also make risk management recommendations to regulators and standard setting bodies in Australian and state and territory governments.
