The Industrial Chemicals Environmental Management Standard (IChEMS) has been developed by all Australian governments to efficiently and effectively manage the risks of industrial chemicals to the environment, while providing consistent requirements for businesses across Australia. The IChEMS Register records standards for the environmental management of chemicals, including risk management measures for specific industrial uses. In turn, the Australian federal government and each state and territory government will enact legislation to implement the standards in their jurisdictions. The proposed standards will assign the following chemicals, and mixtures and articles containing the chemicals, to Schedule 7 of the IChEMS Register. This will prohibit their import, manufacture, use and export in Australia, with exceptions for unintentional trace contamination, research, environmentally sound disposal, articles in use prior to the standards' date of entry into force, and for the presence of 2,4,6-tri-tert-butylphenol in hydrocarbon fuels at a level below or equal to 50 mg/kg. Perfluoroheptanesulfonic acid (PFHpS) and related substances; Perfluorononanesulfonic acid (PFNS), perfluorodecanesulfonic acid (PFDS) and related substances; 2,4,6-Tri-tert-butylphenol
