New U.S. tariffs take effect today after Supreme Court ruling

Fresh U.S. tariffs on imported goods came into effect on Tuesday (February 24, 2026), as President Donald Trump moved to rebuild his trade agenda after the Supreme Court ruled against a swath of his global duties.

The new tariffs, initially set at 10%, are justified as a means “to deal with the large and serious United States balance-of-payments deficits,” according to a White House release on Friday (February 20).

Mr. Trump has since vowed to raise this level to 15%, with exclusions expected to remain for goods covered by sector-specific investigations and the U.S.-Mexico-Canada trade pact.
