As Trump eyes more tariffs, South Korea remains safe haven for GM and Hyundai

DETROIT — As President Donald Trump threatens to further increase tariffs on U.S. trading partners, the greatest impact for the auto industry outside of North America would be additional levies on South Korea and Japan.

The East Asian countries produced a combined 16.8% of vehicles sold last year in the U.S., including a record 8.6% from South Korea and 8.2% from Japan, according to data provided to CNBC by GlobalData.

They were the largest vehicle importers to the U.S. outside of Mexico — and they have little to no duties compared with the 25% tariff Trump has threatened imposing on Canada and Mexico.

Automakers such as General Motors and South Korea-based Hyundai Motor export vehicles tariff-free from South Korea. The country overtook Japan and Canada last year to become the second-largest exporter of new cars to the U.S., based on sales.

It trails only Mexico, which represented 16.2% of U.S. auto sales in 2024, GlobalData reports.

“Obviously Hyundai has a massive amount of exposure. Behind it is GM … with relatively large volume models,” said Jeff Schuster, global vice president of automotive research at GlobalData. “There’s a lot of risk potentially here, but it’s limited, really limited, to those two players.”

Imports from Japan are currently subject to a 2.5% tariff for automakers such as Toyota Motor, Nissan Motor and Honda Motor. Vehicles from Japan represented about 1.31 million autos sold last year in the U.S.

Japan’s percentage of sales has actually decreased in recent years, while South Korea’s exports and sales have continued to rise from less than 845,000 in 2019 to more than 1.37 million in 2024.

South Korea has 0% tariffs on cars despite Trump renegotiating a trade deal with the country during his first term in 2018. That accord was touted for improving vehicle imports to South Korea, but it did little to address vehicle exports to the U.S.

The deal also has done little for increasing automotive exports to South Korea, according to data from the International Trade Commission. U.S. passenger vehicle exports to South Korea have actually decreased by roughly 16%.

Separate from cars, tariffs on trucks exported from South Korea and Japan to the U.S, as well as elsewhere, are 25%.

A tariff is a tax on imports, or foreign goods, brought into the United States. The companies importing the goods pay the tariffs, and some experts fear the companies would simply pass any additional costs on to consumers — raising the cost of vehicles and potentially reducing demand.

GM is the largest foreign direct investor in Korea’s manufacturing industry, according to the automaker’s website. It has invested 9 trillion South Korean won (roughly $6.2 billion) since establishing the operations in 2002.

GM produces its Buick Encore GX and Buick Envista crossovers, as well as the Chevrolet Trailblazer and Chevrolet Trax crossovers, at plants in South Korea. The company has touted the vehicles as being a pinnacle for the automaker’s profitable growth in lower-margin, entry-level vehicles.

“We’re taking out costs of programs, improving profitability and creating vehicles that customers love, like the new Chevy Trax and the Buick Envista,” GM President Mark Reuss said during the company’s investor day in October. “Trax and Envista have helped raise our share of the U.S. small SUV market to its highest level since 2007.”

GM and Hyundai did not immediately respond when asked about potential tariffs on South Korea. Kia declined to comment.

Terence Lau, dean of the College of Law at Syracuse University who previously worked as a trade expert for Ford Motor, said the automotive industry is built on free trade. If tariffs are implemented, the industry can adjust, but it takes time.

“The car industry can adjust to anything. Really, it can. It’s always going to make product that customers want to buy, because personal mobility and transportation is a human need all around the world,” he said. “What the car industry cannot do well is pivot on a dime.”

Lau argued that a single-digit tariff can be a “nuisance,” but once they hit 10% or more, that’s when additional costs can really began eating into the margin or products.

Ford Motor CEO Jim Farley last week argued that if Trump is going to implement tariffs affecting the automotive industry, it should take a “comprehensive” look at all countries to even the playing field in North America.

Farley singled out Toyota and Hyundai for importing hundreds of thousands of vehicles annually from Japan and South Korea, respectively.

“There are millions of vehicles coming into our country that are not being applied to these [incremental tariffs],” Farley said during the company’s fourth-quarter earnings call with investors. “So if we’re going to have a tariff policy … it better be comprehensive for our industry.

“We can’t just cherry-pick one place or the other because this is a bonanza for our import competitors.”

The White House did not respond for comment on potential tariffs on South Korea.

Trump set an Oval Office news conference to discuss his plan to impose reciprocal tariffs on other countries for Thursday at 1 p.m. ET, but it’s unclear whether South Korea and Japan would be included.

Republican U.S. House Speaker Mike Johnson told Reuters on Wednesday that he believed Trump is considering exemptions that would include the automotive and pharmaceutical industries, among others.
