WASHINGTON – President Trump on Wednesday announced he was imposing a 25 percent tariff on foreign-made vehicle imports, marking the latest escalation of his trade war against other nations.

Trump said in the Oval Office that the 25 percent tariff would apply to “all cars not made in the United States.” The tariffs will go into effect on April 2, Trump said.

The president said that if parts are made in America, those parts would not be taxed or tariffed. Many cars are built with parts that originate in multiple different countries before the vehicle is assembled.

“For the most part, I think it’s going to lead cars to be made in one location,” Trump said.

Cox Automotive predicts 700,000 fewer vehicles will be sold in the U.S. this year due to tariff volatility.

Recession fears, production disruptions and higher vehicle prices amid an ongoing trade war constrained the latest sales forecasts, Cox chief economist Jonathan Smoke told media Wednesday.

The Atlanta automotive analytics and software company said it anticipates 15.6 million new vehicles will be sold in the U.S. in 2025, down 4.3% from the 16.3 million it originally forecast.

Trump argued the tariffs would encourage foreign car producers to move production into the United States and boost jobs in the long run. But the tariffs could lead to higher prices for cars in the meantime, as it could increase the cost for manufacturers to bring in certain parts.

“We’re signing an executive order today that’s going to lead to tremendous growth in the automobile industry,” Trump told reporters.

The move is likely to hit Japan, South Korea and Germany particularly hard.

The stock market dipped on Wednesday afternoon in anticipation of Trump’s announcement, which the White House had previewed earlier in the day.
