President Donald Trump announced Saturday he will increase a temporary tariff on U.S. imports from 10% to 15%, the maximum allowed by law. This action follows a U.S. Supreme Court ruling that struck down his previous tariff program, deeming he had exceeded his authority.

The new levies are based on Section 122, a law permitting tariffs up to 15% but requiring congressional approval for extensions beyond 150 days. This statute has not been previously invoked by a president and could face further legal scrutiny.

Trump stated he will utilize the 150-day period to pursue other "legally permissible" tariffs, intending to rely on statutes that allow import taxes based on national security or unfair trade practices.

Trade experts express skepticism that Congress will extend these tariffs, citing public concerns over higher prices. The Supreme Court's decision, authored by Chief Justice John Roberts, concluded the law Trump used for most tariffs did not grant the presidential powers claimed.

Some foreign leaders welcomed the ruling, emphasizing the importance of checks and balances. Meanwhile, trade representatives confirmed that existing negotiated rates above the universal tariff level will remain in place for certain countries.
