US Tariffs: Supreme Court Ruling & Global Trade Impact

Governments and companies around the world scrambled today to determine the impact of the US Supreme Court ruling that struck down some of the Trump administration’s sweeping global tariffs. The decision, delivered Friday, is a major setback for President Trump, who responded by imposing a new 10% “global tariff” that will take effect “almost immediately.” He subsequently announced Saturday morning that he would raise the tariff to 15%.

The latest twist in the US tariff roller coaster, launched when President Donald Trump returned to office 13 months ago, has roiled trade officials from South Korea to South America and beyond. South Korea’s Trade Ministry called for an emergency meeting Saturday (local time) to understand the new landscape. While some specific exports to the US, like automobiles and steel, aren’t affected by the US high court decision, those that are will likely now be covered by the new 10% tariff.

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.” However, he cautioned against any triumphalism, noting that Trump had already signaled his intention to implement new tariffs.

“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.”

Businesses brace south of the border – and beyond

In Mexico, Sergio Bermúdez, head of an industrial parks company in Ciudad Juárez, expressed skepticism about Trump’s latest announcement. “Trump says a lot of things, and many of them aren’t true,” he said. “All of the businesses I know are analysing, trying to figure out how it’s going to affect them.”

The impact could be particularly significant in Juarez, where much of the economy depends on factories producing goods for export to US consumers, a result of decades of free trade between the two countries.

The policy shifts in the United States over the past year have made many global business leaders cautious, impacting investment decisions. Alan Russell of Tecma, which helps American businesses set up operations in Mexico, said his company’s workload has surged fourfold as it grapples with new import requirements. He fears the latest US moves will only exacerbate the challenges.

“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.”

Mexico’s Economy Secretary Marcelo Ebrard said Friday (local time) that 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 US next week to meet with economic officials.

Looking for a piece of possible tariff refunds

Some US importers who paid what may turn out to be excess tariffs are exploring the possibility of refunds – a process likely to be complex. Foreign companies may also seek to recover overpaid amounts.

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 US importers alone overpaid more than 100 billion euros (approximately $108 billion USD).

Swissmem, a Swiss technology industry association, hailed the Supreme Court’s decision as a “good decision,” noting that its exports to the US fell 18% in the fourth quarter alone – a period when Switzerland faced higher US tariffs than most European countries.

“The high tariffs have severely damaged the tech industry,” Swissmem President Martin Hirzel said. “However, today’s ruling doesn’t win anything yet.”

Taiwan, home to the world’s leading contract chipmaker, said the 10% flat tariff rate would, according to an initial assessment, have a “limited impact” on its economy. The island will continue to “closely monitor” developments and maintain close communication with the US to understand the specific measures and respond in a timely manner, the Taiwanese cabinet said in a statement on Saturday.

The U.S. Supreme Court voted 6-3 to strike down large parts of President Trump’s tariff policies Friday, according to the court’s ruling. The law that undergirds the import duties “does not authorize the President to impose tariffs,” the majority ruled.
