President Trump issued Proclamation 10984 last month to announce that the U.S. will levy a 25 percent tariff on MHDVs and their parts and a 10 percent tariff on buses under Section 232 of the Trade Expansion Act of 1962. The issuance of these tariffs is the result of a Commerce Department investigation in April that found the offshore manufacturing of such medium- and heavy-duty trucks and buses constitutes a national security risk due to the reliance of the U.S. military as well as civilian medical, law enforcement, and disaster relief efforts on such vehicles. |
