President Trump said on Wednesday that he would impose a 25 percent tariff on cars and car parts that were imported into the United States, a move that is likely to raise prices for American consumers and throw supply chains into disarray as the president seeks to bolster U.S. manufacturing.

The tariffs will go into effect on April 3 and apply both to finished cars and trucks that are shipped into the United States and to imported parts that are assembled into cars at American auto plants. Those tariffs will hit foreign brands as well as American ones, like Ford Motor and General Motors, which build some of their vehicles in Canada or Mexico.

Nearly half of all vehicles sold in the United States are imported, as well as nearly 60 percent of the parts in vehicles assembled in the United States. That means the tariffs could push up car prices significantly when inflation has already made cars and trucks more expensive for American consumers.
