Aisin Seiki Co. said Friday it expects to take a hit of ¥30 billion to ¥40 billion if the United States raises tariffs on autos and auto parts.

"Any dramatic change (in tariffs) would be a concern," Kiyotaka Ise, president of the auto parts giant, told reporters.

Global automakers and components suppliers are bracing for the possibility of a rise in U.S. auto import tariffs, which could cloud their outlook as it would raise the cost of selling cars in the world's second-biggest vehicle market.
