Global leaders and businesses pore over fallout of more US tariff swoons

SEOUL, South Korea (AP) — Governments and companies around the world scrambled Saturday to determine the impact of the U.S. Supreme Court ruling that struck down some of the Trump administration sweeping global tariffs.

The latest twist in the U.S. tariff roller coaster ride, launched when President Donald Trump returned to office 13 months ago and upended dozens of trading relationships with the world’s biggest economy, roiled trade officials from South Korea to South America and well beyond.

South Korea’s Trade Ministry called for an emergency meeting Saturday to understand the new landscape. Some specific exports to the U.S., like automobiles and steel, aren’t affected by the U.S. high court decision. Those that are affected will likely now be covered by a new 10% tariff imposed by an executive order Trump signed Friday. Trump announced Saturday morning that he would raise the tariff to 15%.

In Paris, French President Emmanuel Macron hailed the checks and balances in the United States, praising the “rule of law” during a visit to a Paris agricultural fair: “It’s a good thing to have powers and counter-powers in democracies. We should welcome that.”

But he cautioned against any triumphalism.

Officials were going over the language of bilateral or multilateral deals struck with the U.S. in recent months, even as they braced for new swings. Trump said Friday he plans new 10% global tariffs, under different rules.

“I note that President Trump, a few hours ago, said he had reworked some measures to introduce new tariffs, more limited ones, but applying to everyone,” Macron said. “So we’ll look closely at the exact consequences, what can be done, and we will adapt.”

Alluding to the new 10% tariff threat, Sergio Bermúdez, head of an industrial parks company in Ciudad Juárez, Mexico, along the Texas border, said Trump “says a lot of things, and many of them aren’t true. All of the businesses I know are analyzing, trying to figure out how it’s going to affect them.”

The impact could be felt especially in Juarez: Much of its economy depends on factories producing goods to export to consumers in the U.S., the result of decades of free trade between the U.S. and Mexico.

The policy swoons in the United States over the last year have made many global business leaders cautious, as they struggle to forecast and see investment take a hit.

Economy Secretary Marcelo Ebrard on Friday said Mexico was watching the tariffs with a “cool head,” noting that 85% of Mexico’s exports face no tariff, largely because of the United States-Mexico-Canada agreement. He plans a trip to the U.S. to meet with economic officials next week.

CEO Alan Russell of Tecma, which helps American businesses set up operations in Mexico, has seen his job grow increasingly complicated over the past year — his company’s workload has surged as much as fourfold as it grapples with new import requirements. He worries the last U.S. moves will only make things more difficult.

“We wake up every day with new challenges. That word ‘uncertainty’ has been the greatest enemy,” said Russell, who is American. “The difficult part has been not being clear what the rules are today or what they’re going to be tomorrow.

Some U.S. importers who paid what may turn out to be excess tariffs are looking for possible refunds — likely a very complex process — and some foreign companies may want to get their piece, too.

Bernd Lange, chairman of the European Parliament’s trade committee, insisted on Deutschland radio that excess tariffs “must be refunded.” He estimates German companies or their U.S. importers alone overpaid more than 100 billion euros ($118 billion).

Swissmem, a top technology industry association in Switzerland, hailed a “good decision” from the Supreme Court, writing on X that its exports to the U.S. fell 18% in the fourth quarter alone — a period when Switzerland was facing much higher U.S. tariffs than most neighboring countries in Europe.

“The high tariffs have severely damaged the tech industry,” Swissmem President Martin Hirzel said on X, while acknowledging the dust is far from settled. “However, today’s ruling doesn’t win anything yet.”
