US-Australia FTA — qualifying goods may enter duty-free

Australia is a significant source of iron and steel imports into the United States, with approximately $42B in total bilateral trade.

Following the Supreme Court's landmark February 20, 2026 decision striking down IEEPA tariffs, imports of iron and steel from Australia are now subject to a 10% tariff under Section 122 of the Trade Act of 1974, effective February 24, 2026.

This 10% rate has a built-in expiration: Section 122 limits presidential tariff authority to 150 days, meaning the tariff expires approximately July 24, 2026 without congressional renewal.

Iron and Steel (HTS Chapter 72) carry an average MFN duty rate of 1.8% in addition to the Section 122 tariff. No additional Section 232 or Section 301 surcharges apply to most products in this category from Australia.

Australia is party to the US-Australia FTA, which may provide preferential or duty-free access for qualifying iron and steel. Importers should verify rules of origin requirements to take advantage of preferential rates.

Key products in HTS Chapter 72 imported from Australia include Hot-rolled steel coils, Cold-rolled steel sheets, Steel rebar, Stainless steel, Steel wire, and Steel pipe and tube.
