Salt is the cargo that defines the port of Onslow (UN/LOCODE AU ONS), located roughly 1,000 kilometres north of Perth in Western Australia's Pilbara region, where Mitsui-operated Onslow Salt ships bulk product from its solar salt fields. Just 7.5 nautical miles to the west lies the separately administered Wheatstone Marine Terminal, part of the Port of Ashburton, which has served Chevron's Wheatstone LNG plant since its first cargo in October 2017 and now supports two trains with a combined capacity of 8.9 million tonnes per year. Onslow and Ashburton share a common port boundary but are distinct facilities, and the two should not be confused in cargo planning. Onslow itself is configured for bulk handling rather than containers, and no scheduled container service is documented there. No publicly verified figures describe customs procedures specific to Onslow's salt exports; shippers needing broader cargo capability typically look to Dampier or Port Hedland further up the Pilbara coast.
