WASHINGTON (Reuters) - The White House on Wednesday raised the possibility that impending hefty U.S. tariffs on steel and aluminum imports could exclude a clutch of countries other than Canada and Mexico as President Donald Trump planned to authorize the measures on Thursday.
Trump is expected to sign a presidential proclamation establishing the tariffs during a ceremony scheduled for 3:30 p.m. (2030 GMT) on Thursday, a source familiar with the situation said. A senior U.S. official said the measures would take effect about two weeks after Trump signs the proclamation.
The tariffs would impose a duty of 25 percent on steel and 10 percent on aluminum to counter cheap imports, especially from China, that he says undermine U.S. industry and jobs.
It was not immediately clear whether the proclamation would list countries to be exempted as pressure grew for Trump to exclude U.S. allies from the action.
“We expect that the president will sign something by the end of the week and there are potential carve-outs for Mexico and Canada based on national security, and possibly other countries as well based on that process,” White House spokeswoman Sarah Sanders told a regular media briefing. “It will be country by country, and it will be based on national security.”
Action that does not include exemptions risks retaliatory tariffs on U.S. exports - not least by Canada and Europe - and complicates already tough talks on the North American Free Trade Agreement (NAFTA).
Trump said on Monday that Canada and Mexico would only be excluded after the successful renegotiation of NAFTA.
The benchmark Standard & Poor’s 500 stock index ended slightly lower after a volatile session after Trump promised the tariffs but then said Mexico and Canada could be exempt. The S&P closed 0.05 percent lower after being down 0.4 percent, while the Dow Jones Industrial Average ended down 0.33 percent. The U.S. dollar pared gains to end little changed, while the Canadian dollar and Mexican peso pared some losses.
The departure of Trump’s chief economic adviser Gary Cohn, who was seen as a bulwark against Trump’s economic nationalism, clears the way for greater influence by trade hard-liners such as Commerce Secretary Wilbur Ross and Peter Navarro, Trump’s trade policy adviser, and the possibility that the tariffs will be implemented.
Sanders said Trump was considering several candidates to fill Cohn’s position, while Navarro said he was not short-listed for the job.
In his first tweet on Wednesday, Trump showed no sign of backing down, saying the United States had lost more than 55,000 factories and 6 million manufacturing jobs and let its trade deficit soar since the administration of President George H.W. Bush.
As pressure mounted against the tariffs, a leading business lobby group warned that the move would imperil U.S. manufacturing and jobs. Iowa’s congressional delegation, including
