On March 17, 2021, the Australian Anti-Dumping Commission issued an announcement that it had made a final anti-dumping (AD) ruling on aluminum micro-extrusions from China, ruling that there had no dumping by Guangdong Jiangsheng Aluminium Co., Ltd. and Guangdong Zhongya Aluminium Co., Ltd., the companies involved in this case, and no substantial injury was caused to the Australian industry. Therefore, the AD investigation was decided to be terminated.

The initial AD investigation was launched on February 17, 2020 based on the application submitted by the Australian Aluminium Shapemakers Pty Ltd.
