President Donald Trump said he would likely impose tariffs on automobile, semiconductor and pharmaceutical imports of around 25%, with an announcement coming as soon as April 2, a move that would dramatically widen the president’s trade war.

Trump has previously announced 25% tariffs on steel and aluminum that are set to take effect in March. Tuesday’s comments are his most detailed yet in specifying other sectors to be hit with fresh barriers if implemented.

“I probably will tell you that on April 2, but it’ll be in the neighborhood of 25%,” Trump told reporters at his Mar-a-Lago club when asked about his plan for auto tariffs.

Asked about similar levies on pharmaceutical drugs and semiconductor chips, the president said: “It’ll be 25% and higher, and it’ll go very substantially higher over a course of a year.” Trump said he wanted to give companies “time to come in” before announcing new import taxes.

“When they come into the United States and they have their plant or factory here there is no tariff, so we want to give them a little bit of a chance,” he said.

New levies on automobiles would have sweeping effects on the industry. The roughly 8 million passenger cars and light trucks brought into the U.S. last year accounted for about half of U.S. vehicle sales. European carmakers, including Volkswagen AG, and Asian companies, including Hyundai Motor Co., would be among the most affected.

“European automakers may face challenges in maintaining market share, as most would struggle to pass such tariffs onto consumers or absorb the cost themselves given already thin margins,” said Rella Suskin, equity analyst at Morningstar.

Trump didn’t specify whether the measures would target specific countries or apply to all vehicles imported to the U.S. It’s also unclear whether cars made under a free trade agreement with Canada and Mexico would be spared from industry-specific duties, should they take effect.

While there are scant details about the latest tariff threat, it’s clear that the targets in Trump’s second trade war have broadened beyond China and will hit Asia in particular, according to Alicia Garcia Herrero, chief economist for the Asia Pacific region at Natixis SA.

“In relative terms, Trump 2.0 is clearly going to hit everybody,” she said. “Whoever thought that the rest of Asia outside of China may be a winner in this trade war was wrong.”

Globally, the countries most exposed to the most recent announcement include Mexico and South Korea, where exports of passenger cars to the U.S. are equal to 2.4% and 1.8% of gross domestic product respectively, according to Bloomberg Economics. When it comes to chips, Malaysia and Singapore are among the most exposed.

Auto making powerhouses South Korea and Japan are also in the line of fire, particularly if recent levies are stacked with prior ones. Japan — where auto exports make up the largest chunk of outbound shipments and the U.S. is the largest market — has already raised the issue with the White House.

A new 25% tariff would equate to a third of Toyota’s fiscal 2025 profit guidance and nearly half of Honda’s, Bloomberg Intelligence research shows.

Industry experts, lobby groups and executives have warned that steep new tariffs on the industry would have broad ripple effects, including higher prices for consumers and steep new costs for the industry.
