From bdo.com.au: US steel and aluminium tariffs, including a 25 percent duty rate, started to apply to Australian imports from 12 March 2025.

Exporters to the US must identify if their goods fall under HSEN classifications affected by additional tariffs and assess the value and weight of steel and aluminium within those goods.

It is essential to prepare documentation reflecting this information and retain supporting documents for compliance with US Customs and Border Protection.
