In a Cargo Systems Messaging Service (CSMS) bulletin published on May 1, 2025, U.S. Customs and Border Protection (CBP) issued guidance on certain automobile parts subject to Section 232 duties.

This guidance reviews the 25% ad valorem tariffs on all imports of certain automobile parts from all countries that came into effect on May 3, 2025. The guidance provides entry filing instructions, including a review of the applicable chapter 99 Harmonized Tariff Schedule of the United States (HTSUS) classifications, exemptions, and chapter 98 provisions.

No drawback shall be available for these automobile parts duties.

Any automobile parts may only be admitted into a foreign trade zone under “privileged foreign status” and will be subject to these additional duty rates; unless the product is eligible for admission under “domestic status.”
