* U.S. tariff measures on aluminum and steel under President Donald Trump’s first term

On June 1, 2018, the United States formally imposed additional tariffs of 25% on imported steel and 10% on imported aluminum from most countries.

Subsequently, the United States implemented tariff-rate quotas (TRQs) to suspend these tariffs for specified volumes of steel and aluminum imports from the European Union, Japan, and the United Kingdom, and suspended tariffs on steel imports from Ukraine until June 1, 2025.

On February 8, 2020, these tariffs were extended to certain steel and aluminum derivative products. However, the United States granted exclusions for steel derivative products from Argentina, Australia, Brazil, Canada, the European Union, Japan, South Korea, Mexico, and the United Kingdom, and for aluminum derivative products from Argentina, Australia, Canada, the European Union, Mexico, and the United Kingdom.

On February 10, 2025, President Donald Trump issued separate proclamations directing a series of actions to expand and increase Section 232 tariffs on steel, aluminum, and steel and aluminum derivative products. Specifically:

- The additional tariff on steel remains at 25%, but is expanded to apply to imports from all countries;

- The additional tariff on aluminum is increased from 10% to 25%, and is applied to imports from all countries;

- The tariffs are extended to cover a broader range of additional derivative products;

- All tariff suspension agreements and exemptions previously granted to Argentina, Australia, Brazil, Canada, the European Union, Japan, Mexico, South Korea, Ukraine, and the United Kingdom are terminated;

- All General Approved Exclusions (GAEs) are revoked (however, they remain valid until their expiration date or until the exempted import volume is exhausted, whichever occurs first).

The exclusion request process was also terminated as of February 10, 2025.

The above changes entered into force on March 12, 2025.
