U.S. Expands Steel and Aluminum Tariffs to 407 Additional Product Codes

The latest action broadens the scope of Section 232 tariffs, bringing hundreds of products with metal content under higher steel and aluminum duties.

The U.S. Department of Commerce, through the Bureau of Industry and Security (BIS), has expanded steel and aluminum tariffs by designating 407 additional Harmonized Tariff Schedule of the United States (HTSUS) product codes.

These products are now subject to Section 232 duties based on their metal content.

A 50% duty rate will be assessed on the value of the steel or aluminum content in the covered products for goods entered for consumption, or withdrawn from warehouse for consumption, on or after 12:01 a.m. Eastern Time (ET) on August 18, 2025.

The non-steel and non-aluminum content of the goods will remain subject to reciprocal and other applicable tariffs.

60 HTS product codes were not included at this time because they are still under ongoing investigations.

This update is scheduled to be published in a Federal Register Notice on August 19, 2025.

It follows a similar move last month, where the U.S. expanded its Section 232 tariff list to include certain home appliances containing steel parts.

These goods became subject to 50% duties as of June 23, 2025—just a week after the U.S. doubled tariffs on steel and aluminum from 25% to 50%.

Steel and aluminum products added to tariff coverage

The Notice clarifies the amendments that bring 407 additional product codes under Section 232 steel and aluminum tariffs.

Accordingly, the following changes will apply to goods entered for consumption, or withdrawn from warehouse for consumption, on or after 12:01 a.m. EDT, August 18, 2025:

• Review your shipments to determine if your goods fall within the codes now covered by Section 232.
• Assess the impact on your business and update your pricing models to accommodate the new duty rate.
• Consult a customs broker to ensure accurate tariff calculation and documentation.
