On 4 December 2012, the Minister for Industry and Innovation announced changes to Australia’s anti‑dumping regime. The key regulatory change is that the lesser duty rule need not apply under some circumstances when determining the size of the dumping duty to impose on an importer. This may result in shorter investigation times, but will also mean that higher dumping duties may be payable by importers. The other major regulatory change is that importers who are under investigation for dumping will be required to declare whether or not a good they are importing has been dumped (subsidised). The effect of this will be that the importer will be required to investigate their supplier for evidence if the good has been subsidised, which potentially may reveal information of value to an investigation. A Regulation Impact Statement was prepared by the Department of Industry, Innovation, Science, Research and Tertiary Education and assessed as adequate by the Office of Best Practice Regulation.
