Trump Orders Truck Import Probe, Setting Stage for Tariffs

President Donald Trump’s administration started an investigation into the need for tariffs on imports of medium- and heavy-duty trucks and parts, an expansion of his trade war that has hit hundreds of nations and sectors.

The Commerce Department will probe the national security risks stemming from a “small number” of foreign suppliers that it says have dominated US imports in part due to government subsidies and “predatory trade practices,” according to a Federal Register notice.
