Trump Orders 10% Global Tariff After Supreme Court Strikes Down His Tariff Power

President Donald Trump announced Friday he will impose a 10 % global tariff after the U.S. Supreme Court struck down his sweep of tariffs as illegal, a major escalation in the ongoing trade policy fight. According to Reuters, Trump said he will sign an executive order imposing the tariff under Section 122 of the Trade Act of 1974, even as his broader tariff strategy faces legal turbulence.

The Supreme Court’s 6–3 ruling Friday held that Trump exceeded his authority by using emergency economic powers to impose global tariffs, invalidating a central plank of his second-term economic agenda. The decision limits executive power over trade without congressional approval.

Under the new plan, Trump’s 10 % tariff would cover all nations and kick in soon, adding onto existing levies under current law and lasting up to 150 days unless Congress acts. Treasury officials noted that other tariff paths may be explored as well, including Section 301 probes and national security tariffs under Section 232.

This move comes amid sharp pushback from Democratic lawmakers, who hailed the court ruling as a “win for the wallets” of consumers and small businesses. Senate Democratic leader Chuck Schumer said the decision will relieve tariff-induced price pressures.

At the same time, hundreds of companies have already demanded refunds for tariffs paid under the invalidated regime, raising legal questions about past levies.

Legal experts note Section 122 allows only a temporary tariff and caps rates, meaning any long-term trade strategy requires legislative backing.

What happens next is likely a legal battle in lower courts over refund claims and a potential congressional fight over permanent tariff authority.
