These vehicles are crucial for the military, emergency services, and moving essential goods. Starting soon, import limits will help boost U.S. manufacturing and keep our supply chains strong, with changes affecting companies and buyers in this industry. ## Effects PRIA read - 25% Tariff on Medium/Heavy Trucks: cost, high. If you import medium- or heavy-duty vehicles (MHDVs) or the specified MHDV parts, those imports will be subject to a 25% ad valorem duty beginning November 1, 2025. The 25% tariff applies to goods entered for consumption or withdrawn from warehouse for consumption on or after 12:01 a.m. eastern day… - 10% Duty Specifically for Buses: cost, medium. If you import buses (HTSUS heading 8702), those imports will be subject to a 10% ad valorem duty beginning November 1, 2025. This 10% rate is specified separately from the 25% rate that applies to other MHDVs. - USMCA Content Can Limit Tariff Base: benefit, medium. If your imported MHDV qualifies for preferential treatment under USMCA, you may submit documentation showing United States content so that the Secretary may allow the 25% duty to apply only to the non‑United States content of that model. For many MHDV parts, USMCA claimants will not be subject to t… - 3.75% Offset for U.S.-Assembled MHDVs: benefit, medium. If you are an MHDV manufacturer that assembles vehicles in the United States, you may apply to the Secretary for an import adjustment offset equal to 3.75% of the aggregate value of all MHDVs you assemble each year from November 1, 2025 through October 31, 2030. Only MHDVs that undergo final assemb… - Engine Manufacturers Eligible for Same Offset: benefit, medium. The Secretary will establish a process for MHDV engine manufacturers equivalent to the 3.75% import adjustment offset; offsets for engine manufacturers will be based on the aggregate value of engines assembled in the United States over the same November 1, 2025 through October 31, 2030 period. Engi… - Penalty if U.S. Content Is Overstated: cost, medium. If Customs finds that you overstated the declared U.S. content of an imported MHDV, the 25% tariff will apply to the full value of that MHDV and to all imports of the same model by the same importer from the date of the inaccurate declaration until CBP verifies compliance. This applies when CBP det… - Secretary Can Add More Parts to Tariff List: cost, medium. The Secretary may establish a process and add additional medium- and heavy-duty vehicle parts (MHDVPs) to the scope of the tariffs if doing so would reduce or eliminate the national security threat. The process may include receiving information and requests from domestic parts producers or other in… - Limit on Drawback Claims for Parts Duties: cost, low. As of the effective date, only manufacturing drawback claims under sections 1313(a)-(b) of the Tariff Act of 1930 are available for duties imposed on MHDVPs and automobile parts under the related proclamations. The Secretary may adjust a company's offset accrual amount to avoid awarding excessive o… - Steel/Aluminum Rate Adjustments for Canada/Mexico Suppliers: mixed, medium. The Secretary may reduce tariffs under the earlier steel and aluminum proclamations by up to half for producers that operate facilities in Canada or Mexico and supply U.S. automobile or MHDV manufacturers, limited to newly committed U.S. production capacity; any adjusted rate cannot be lower than 2… - 25-Year Old Vehicle Exemption: benefit, low. Imports of MHDVs and buses that were manufactured at least 25 years before the date of entry are not subject to the tariffs under this proclamation. This exemption applies to entries on or after the proclamation's effective date. ## Related documents - [2026-20855](https://policyrisk.com/federal-register/2026-20855): Emergency Tax Relief on Diesel Fuel, 2026-10-09 - [2026-20629](https://policyrisk.com/federal-register/2026-20629): National Manufacturing Day, 2026, 2026-10-07 - [2026-20320](https://policyrisk.com/federal-register/2026-20320): Eliminating Disease-Carrying Pests and Restoring Enjoyment of the Great Outdoors, 2026-10-02 - [2026-20319](https://policyrisk.com/federal-register/2026-20319): Streamlining Access to Government Services Through America.gov, 2026-10-02 - [2026-19554](https://policyrisk.com/federal-register/2026-19554): Restriction on Entry of Certain Nonimmigrant Workers, 2026-09-23 - [2026-19555](https://policyrisk.com/federal-register/2026-19555): Enhancing Program Integrity and Interagency Coordination in the Administration of the H-1B Nonimmigrant Visa Program, 2026-09-23 ## Sources - [2025-19639 on federalregister.gov](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) - [2025-19639 as published (PDF)](https://www.govinfo.gov/content/pkg/FR-2025-10-22/pdf/2025-19639.pdf) ## Related - [Previous: 2025-19617, Continuation of the National Emergency With Respect to the Democratic Republic…](https://policyrisk.com/federal-register/2025-19617) - [Next: 2025-19640, National Cybersecurity Awareness Month, 2025](https://policyrisk.com/federal-register/2025-19640) - [All Federal Register documents](https://policyrisk.com/federal-register) Source: PRIA, https://policyrisk.com/federal-register/2025-19639 (as of 2026-06-08).
