This message is from May 6, 2026. Later CSMS messages may have changed it. See the latest trade news
What did CBP announce?
CBP issued guidance on applying the 25 percent Section 232 duty under Proclamation 10984 only to the non-U.S. content of USMCA-qualifying medium- and heavy-duty vehicles approved by the Commerce Department. The rule covered entries filed on or after November 1, 2025. CBP required importers to report the non-U.S. content on one line under HTSUS 9903.74.03 at 25 percent and the U.S. content on a second line under HTSUS 9903.74.06 at 0 percent, using the same HTSUS number and country of origin on both lines.
What is Allied's position?
At the time, we filed approved USMCA medium- and heavy-duty vehicle entries using the two-line reporting method CBP described, splitting non-U.S. and U.S. content values across HTSUS 9903.74.03 and 9903.74.06. Later CSMS messages may have changed these instructions or the Section 232 program itself. Clients with pending or past MHDV entries under this program should ask Allied to review their current filing requirements.

What does the CBP message say?
The purpose of this message is to provide guidance on applying the 25 percent Section 232 duties imposed by Proclamation 10984 exclusively to the value of the non-U.S. content for approved imports of MHDVs qualifying for preferential tariff treatment under the United States-Mexico-Canada Agreement (USMCA).
BACKGROUND
On October 17, 2025, Presidential Proclamation 10984 authorized the Secretary of Commerce to approve imports of MHDVs qualifying for preferential tariff treatment under USMCA to be eligible to apply the ad valorem tariff of 25 percent exclusively to the value of the non-U.S. content of the MHDV. See 90 FR 48451 (https://www.federalregister.gov/documents/2025/10/22/2025-19639/adjusting-imports-of-medium--and-heavy-duty-vehicles-medium--and-heavy-duty-vehicle-parts-and-buses).
On February 2, 2026, the Commerce Department issued “Procedures for Submissions by Importers of Medium- and Heavy-Duty Vehicles Qualifying for Preferential Tariff Treatment Under the USMCA To Determine U.S. Content”. See 91 FR 4504 (https://www.federalregister.gov/documents/2026/02/02/2026-02049/procedures-for-submissions-by-importers-of-medium--and-heavy-duty-vehicles-qualifying-for).
