WASHINGTON (Reuters) - U.S. President Donald Trump's 25% autos tariffs will cover nearly $600 billion worth of vehicles and auto parts and extend to all computer imports into the U.S., including laptops, according to a Reuters analysis of tariff codes included in a federal register notice on Wednesday.

The update of Trump's autos tariff proclamation from last week included nearly 150 auto parts categories that will face tariffs starting on May 3, a month after Thursday's midnight activation of 25% tariffs on vehicle imports.

The list includes tariff codes for engines, transmissions, lithium-ion batteries and other major components, along with less expensive parts including tires, shock absorbers, spark plug wires and brake hoses.

But a major surprise was the inclusion of the four-digit tariff code covering all computers, which are among the biggest global import categories into the U.S. at $138.5 billion in 2024, according to U.S. Census Bureau data.
