US Tariffs on Inorganic Chemicals from Australia — 10% (2026)

The United States imports substantial quantities of inorganic chemicals from Australia, with approximately $42B in total bilateral trade.

The current tariff framework for inorganic chemicals from Australia reflects the post-SCOTUS landscape: a 10% Section 122 tariff replaced the previously higher IEEPA rates after the Court's February 2026 ruling.

The Section 122 tariff is subject to a 150-day statutory time limit and is set to expire approximately July 24, 2026, unless Congress acts to extend or replace it. Importers should monitor legislative developments closely as this deadline approaches.

Inorganic Chemicals (HTS Chapter 28) carry an average MFN duty rate of 3.2% 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 inorganic chemicals. Importers should verify rules of origin requirements to take advantage of preferential rates.

Key products in HTS Chapter 28 imported from Australia include Hydrochloric acid, Sulfuric acid, Sodium hydroxide, Hydrogen peroxide, Titanium dioxide, and Rare-earth compounds.
