The Trump administration will delay tariffs on cars and auto part imports for six months while it negotiates trade deals with Japan and the European Union, the White House announced Friday.

President Trump said the Commerce Secretary Wilbur Ross has concluded "that the present quantities and circumstances of automobile and certain automobile parts imports threaten to impair" national security. Trump cited the same "Section 232" authority that he used to impose tariffs on steel and aluminum.

The administration had set a Saturday deadline to decide whether to impose tariffs on autos over national security concerns.
