Additional tariffs of 25 percent on imported steel, and 10 percent on imported aluminum, were imposed effective June 1, 2018, with respect to nearly all countries. The U.S. has since negotiated agreements to impose tariff-rate quotas suspending these tariffs on a set volume of steel and aluminum products imported from the European Union, Japan, and the United Kingdom.

Lists of affected products can be found in the annexes to proclamations 9704 on aluminum (available here) and 9705 on steel (available here).

The tariffs were extended to certain derivatives of steel and aluminum articles as of Feb. 8, 2020, though there are exceptions for Argentina, Australia, Brazil, Canada, the European Union Japan, Korea, Mexico, and the United Kingdom for derivatives of steel and for Argentina, Australia, Canada, the EU, Mexico, and the UK for derivatives of aluminum.

Lists of affected derivative products can be found in the annexes to proclamation 9980 (available here).

Effective June 1, 2022, the U.S. suspended the Section 232 tariffs on steel imported from Ukraine, and that suspension is currently scheduled to remain in effect through June 1, 2025.

Effective March 10, 2023, the U.S. increased the Section 232 tariff on aluminum articles and derivative aluminum articles that are the product of Russia to 200 percent. Effective April 10, 2023, the U.S. imposed a 200 percent tariff on aluminum articles and derivative aluminum articles where any amount of primary aluminum used in the manufacture of those articles is smelted in Russia, or the articles are cast in Russia (although any country that imposes a tariff of 200 percent or more on its imports of aluminum articles that are products of Russia may be exempt from these tariffs).

Exclusions from the Section 232 tariffs may be granted if it is determined that a given steel or aluminum article (1) is not produced in the U.S. in a sufficient and reasonably available amount or of a satisfactory quality or (2) should be excluded based on specific national security considerations.” The rules for submitting and considering exclusions requests have been amended several times; a summary of the most recent changes is available here.
