What Every Multinational Should Know About … The New Rules for Section 232 Tariffs on Steel, Aluminum, and Copper Derivatives - Foley & Lardner LLP

Importers, customs brokers, and trade compliance officers should be aware of recent developments concerning Section 232 tariffs. New rules pertaining to tariffs on steel, aluminum, and copper derivatives have been introduced, as highlighted in an announcement published on May 27, 2026. This signifies a critical update to the existing trade landscape for these materials, necessitating immediate attention from affected businesses.

These new rules are particularly relevant for multinational companies and any entity involved in the importation of steel, aluminum, and copper derivatives into the United States. Section 232 of the Trade Expansion Act of 1962 allows the President to impose tariffs or other restrictions on imports if they are determined to threaten national security. Changes to these rules can significantly impact import costs, supply chain strategies, and overall trade compliance obligations for a wide range of industries, from manufacturing to construction.

While the specific details regarding the revised tariff rates, effective dates for these new rules, or the precise nature of the changes to the Section 232 framework are not enumerated in the immediate summary, the announcement itself on May 27, 2026, underscores the need for vigilance. Importers of steel, aluminum, and copper derivatives must understand that the regulatory environment for these goods has shifted, and previous assumptions about tariff liabilities may no longer hold true.

In light of these new rules, importers and trade compliance professionals are strongly advised to take proactive steps. This includes reviewing current Harmonized Tariff Schedule (HTS) classifications for all imported steel, aluminum, and copper derivative products to ensure accuracy. Furthermore, it is crucial to assess existing supply chain agreements and potential impacts on landed costs. Consulting with legal counsel or trade compliance experts is highly recommended to interpret the full scope of these new regulations and to ensure ongoing compliance, mitigate risks, and adapt import strategies accordingly.
