Supreme Court Allows Trump's Tariffs, Officials Urge Acceptance

The Impact of Trump's Tariffs on U.S. Manufacturing

U.S. factory equipment maker OTC Industrial Technologies has long relied on low-cost countries to supply components, initially turning to China and later India. However, the implementation of President Donald Trump’s tariffs on numerous trade partners has disrupted this supply chain strategy for CEO Bill Canady.

"We moved things out of China and went to some of those other countries, and now the tariffs on those are as bad or worse," Canady explained. "We just have to hang on and navigate our way through this so we don't all go broke in the short run."

This situation is not unique to OTC. Companies, foreign trade ministries, trade lawyers, and economists are grappling with the implications of Trump’s global tariffs as the U.S. Supreme Court considers their legality. With arguments set for Wednesday, it is anticipated that these tariffs will remain in place for the long term under one legal authority or another.

Lower Courts Rule Against Trump

The Supreme Court, which has a 6-3 conservative majority, is hearing the administration's appeal after lower courts ruled that Trump overstepped his authority in imposing sweeping tariffs under a federal law meant for emergencies. If the court strikes down Trump's use of the 1977 International Emergency Economic Powers Act (IEEPA) to impose broad global tariffs, it could eliminate a key tool used to punish countries that draw his ire on non-trade political matters. These include actions such as Brazil's prosecution of former president Jair Bolsonaro and India's purchases of Russian oil that fund Russia's war in Ukraine.

"For decades, our country has been looted, pillaged, raped and plundered by nations near and far, both friend and foe alike," Trump said when announcing sweeping reciprocal tariffs in April under this law.

"Reciprocal - that means they do to us and we do it to them," he added.

Trump is the first president to invoke this statute, which is typically used to apply punitive economic sanctions to adversaries, to impose tariffs. The law gives the president broad authority to regulate various economic transactions when a national emergency is declared. In this case, Trump deemed a $1.2 trillion U.S. goods trade deficit in 2024 a national emergency, despite the fact that the U.S. has had trade deficits every year since 1975. He also cited the overdose crisis involving fentanyl.

U.S. Treasury Secretary Scott Bessent expects the Supreme Court to uphold the IEEPA-based tariffs. However, if the court rules against them, Bessent stated the administration would switch to other tariff authorities, including Section 122 of the Trade Act of 1974, which allows broad 15% tariffs for 150 days to address trade imbalances.

Bessent also mentioned that Trump could invoke Section 338 of the Tariff Act of 1930, a statute allowing tariffs up to 50% on countries that discriminate against U.S. commerce.

"You should assume that they're here to stay," Bessent said of Trump's tariffs.

For countries that have negotiated tariff-lowering trade deals with Trump, "you should honor your agreement," Bessent added. "Those of you who got a good deal should stick with it."

Negotiating Power

Trump administration officials have highlighted the tariffs as a means to push major trading partners like Japan and the European Union to negotiate concessions that help reduce the U.S. trade deficit, arguing that these concessions will endure any Supreme Court ruling.

U.S. trade partners are not waiting for a Supreme Court decision to decide how to proceed. The U.S. Trade Representative's office has finalized framework trade deals with Vietnam, Malaysia, Thailand, and Cambodia, locking in tariff rates of 19% to 20%. South Korea agreed to terms on a $350 billion investment plan, unlocking a 15% tariff for its cars and other goods.

Negotiations with China have proven more challenging due to its willingness to retaliate against the United States and cut off supplies of rare earth minerals and magnets essential for U.S. high-tech manufacturing.

Instead of major concessions, the Trump administration has had to settle for extensions of a delicate truce under which American and Chinese tariffs were reduced to keep the rare earths flowing.

In South Korea last Thursday, Trump agreed in talks with Chinese President Xi Jinping to halve the U.S. tariff rate on Chinese goods related to fentanyl to 10% and to delay tighter technology export controls for a year in exchange for China's year-long pause on its tough licensing requirements for global rare-earth exports.

Xi agreed to resume purchases of American soybeans that China had halted for months, while Trump paused new U.S. port fees for China-linked ships for a year.

Revenue, Investment Concerns

Some investors worry that financial markets, accustomed to the Trump tariff status quo, could face turmoil if the Supreme Court strikes down the IEEPA tariffs.

A major concern, especially in the Treasury debt market, is the risk of refunding more than $100 billion in IEEPA tariff collections and forgoing hundreds of billions of dollars in annual revenue.

The IEEPA tariffs collected so far this year make up the biggest portion of a $118 billion increase in net customs receipts in the 2025 fiscal year that ended on September 30. That helped offset rising healthcare, Social Security, interest, and military outlays, helping shrink the U.S. deficit slightly to $1.715 trillion.

"It's a significant political economy risk that we get addicted to tariff revenue," said Ernie Tedeschi, a senior fellow at the Yale University Budget Lab, adding that makes it harder for any future presidential administration to lower the duties.

Getting the money back would be difficult, as a tariff reversal "is unprecedented at this scale" for U.S. Customs and Border Protection, said Angela Lewis, global head of customs at freight forwarder and customs broker Flexport.

The onus could be on individual importers to apply for "post-summary corrections" with the agency, a messy process that could take years and not be worthwhile for some smaller firms, Lewis said. For those getting refunds, U.S. taxpayers also would be on the hook for 6% annual interest costs compounded daily.

Inflation Timing

The biggest dilemma is managing costs. Importers for the most part have eaten the tariffs, according to academic studies and comments from executives, reducing profit margins but limiting higher consumer prices and protecting market share.

While this has dampened the inflationary impact so far, cost pass-throughs are broadening through clothing and other goods prices, according to Oxford Economics, which estimated that tariffs added 0.4 percentage point to September's Consumer Price Index annual rate of 3.0%, keeping inflation well above the Federal Reserve target.

Corporate earnings have taken the biggest hit, with global companies flagging more than $35 billion in tariff-related costs so far heading into third-quarter earnings season.

Ohio-based OTC designs and builds factory production lines and automation systems. Soon, CEO Canady said, companies like his will have to "place their bets" on where to shift production for a more sustainable cost base. That may mean back to U.S. shores for high-end products, and to Mexico for lower-value parts.

"I think the new normal is going to be 15%," Canady said of Trump's tariffs, regardless of the legal authority he invokes. "They're going call it whatever they need to call it so that it is not challengeable."
