China’s export restrictions target antimony oxides with apurityof 99.99% or higher, as well as other high-purity antimony compounds (99.999%). Producing such high-purity chemical compounds requires advanced processing technologies, and export controls with this high-purity threshold are likely aimed at restricting the export of high value-added antimony products and advanced processing technologies. These ultra-pure products are used in specialised industries, including high-end electronics, optics, and defence applications.
Australia’s ability to mitigate the risks associated with China’s dominance remains limited. China is a net importer of antimony metal. Currently,86%of Australia’s antimony exports are sent to China for processing. Investing in processing capacity and infrastructure for lower-grade antimony products may offer limited strategic value for the United States, as these products will still be available under China's restrictions. Conversely, developing high value-added processing technologies to produce high-purity antimony products carries significant risks, particularly if China decides to retaliate in trade or lift these restrictions. In the latter case, even if alternative processing technologies become available in Australia, the market – including the United States – may still turn to China for more cost-efficient products, potentially rendering Australia's investments obsolete.
