The update
The proclamation applies to imports from every country and stacks on the ordinary duty. Buses and other vehicles classified in HTS heading 8702 pay 10%; medium and heavy-duty vehicles and the listed parts pay 25%.
USMCA-qualifying trucks can pay the tariff only on their non-U.S. content through a Commerce process covered separately on this tracker.
Impact
Fleet buyers, upfitters and parts distributors pay 25% of customs value on covered trucks and parts. For buses the rate is 10%.
What to watch
The parts list is set by HTS line. Passenger cars and light trucks fall under the separate auto action, not this one.
