U.S. trading partners on Friday (February 20,2026) cautiously welcomed a Supreme Court ruling striking down U.S. President Donald Trump’s sweeping global tariffs, with hard-hit Canada saying the levies were always “unjustified.”

But soon after the decision was announced, Mr. Trump vowed to impose a 10% tariff on all imports into the United States under a separate authority.

While the conservative-majority Supreme Court ruled that Trump was not authorised by the International Emergency Economic Powers Act (IEEPA) to impose tariffs, the ruling does not impact sector-specific duties that Mr. Trump has imposed on imports of steel, aluminum and various other goods.

Governments were weighing how all this this would impact commerce with the world’s largest economy, which has been transformed through Mr. Trump’s use of executive authority since he took office a year ago.
