Tariffs pose "huge uncertainty" after Supreme Court ruling, experts say

The Supreme Court's Friday ruling striking down President Trump's "Liberation Day" tariffs volition not escaped U.S. companies from their concerns astir the absorption of commercialized policy.

"There is immense uncertainty" facing businesses and U.S. trading partners pursuing the landmark decision, said William Reinsch, elder advisor astatine the Center for Strategic and International Studies and the erstwhile president of the National Foreign Trade Council. "There is simply a batch of particulate that has yet to beryllium settled — companies don't cognize what they volition beryllium charged."

Mr. Trump himself is kicking up immoderate of that dust. Immediately aft the ruling, helium announced a impermanent 10% planetary taxation connected U.S. imports, earlier hiking the levy to 15% connected Saturday, portion besides blasting the precocious court's determination connected societal media arsenic "ridiculous" and "extraordinarily anti-American."

Heavy stroke for Trump tariffs

The Supreme Court ruled 6-3 that the International Emergency Economic Powers Act, oregon IEEPA, does not authorize the president to enforce broad-based tariffs, sharply curtailing the Trump administration's usage of exigency powers successful commercialized policy. Later that day, Mr. Trump invoked Section 122 of the Trade Act of 1974 to enforce caller duties.

"Any Country that wants to 'play games' with the ridiculous ultimate tribunal decision, particularly those that person 'Ripped Off' the U.S.A. for years, and adjacent decades, volition beryllium met with a overmuch higher Tariff, and worse, than that which they conscionable precocious agreed to. BUYER BEWARE!!!" Mr. Trump said Monday connected Truth Social. 

The White House didn't instantly respond to a petition for comment. 

The court's decision, arsenic good arsenic Mr. Trump's response, raises caller questions for U.S. businesses and overseas trading partners. Some of those partners had negotiated commercialized deals with tariffs higher than the caller 15% rate, experts noted. And due to the fact that the Section 122 tariffs are acceptable to expire successful 150 days unless extended by Congress, American companies are near to ponder the absorption of tariffs and wherever rates mightiness yet settle. 

"Pure tariff chaos"

The Trump medication volition basal by its commercialized deals and expects its partners to bash the same, U.S. Trade Representative Jamieson Greer said Sunday connected "Face the Nation with Margaret Brennan."

Yet determination are signs that immoderate nations whitethorn beryllium reconsidering those commercialized deals, particularly those that reached agreements astatine rates higher than the existent 15% level acceptable by Mr. Trump connected Saturday. 

A apical European Union lawmaker said Sunday helium would suggest pausing ratification of a caller commercialized statement betwixt the EU and the U.S., citing caller uncertainty. India, which earlier this month agreed to a 18% tariff rate in an interim woody with the U.S., has besides postponed a commercialized sojourn to Washington that was aimed astatine finalizing the agreement, according to CNBC. 

"Pure tariff chaos connected the portion of the U.S. administration," Bernd Lange, seat of the European Parliament's planetary commercialized committee, wrote connected societal media. "No 1 tin marque consciousness of it anymore — lone unfastened questions and increasing uncertainty for the EU and different U.S. trading partners."

Greer said helium spoke with his European counterpart this play and has not been told the woody is off.

"The deals were not premised connected whether oregon not the exigency tariff litigation would emergence oregon fall," Greer said connected Face the Nation. "I haven't heard anyone yet travel to maine and accidental the deal's off. They privation to spot however this plays out."

What happens now?

Mr. Trump has turned to Section 122 of the Trade Act of 1974 to regenerate the tariffs struck down by the Supreme Court. That ineligible proviso allows the president to enforce duties of up to 15% for 150 days to woody with "large and serious" balance-of-payment issues. 

After 150 days, the tariffs would request to beryllium extended by lawmakers. That connection could look an uphill ascent successful Congress, Cato Institute commercialized adept Colin Grabow told CBS News, noting that immoderate Republican lawmakers, specified arsenic Sen. Rand Paul of Kentucky, person spoken retired against tariffs.

"The baseline for a batch of radical is that these 15% tariffs are going to beryllium successful spot successful the adjacent 150 days — but beyond that, what does that look like? Also, uncertainty," Grabow said. 

Because Mr. Trump remains committed to tariffs arsenic some an economical and overseas argumentation tool, his medication is expected to proceed pursuing avenues to stiffen import duties, some Grabow and Reinsch told CBS News.

When the Section 122 tariffs expire, Mr. Trump could crook to different commercialized laws, specified arsenic Section 301 of the Trade Act. That proviso would let Mr. Trump to use country-based tariffs if the U.S. Trade Representative determines that different federation is engaging successful unfair commercialized practices. 

But that, too, would rise questions astir timing and wherever the tariffs could beryllium acceptable nether caller provisions, Grabow said.

"No 1 should beryllium nether the impression, due to the fact that of the IEEPA ruling, that the tariff question has been solved," helium said. "The lone questions are, 'What are the nonstop levels, what are the tools and erstwhile volition they travel into force?'"

Modest economical impact

The existent effectual U.S. tariff complaint — excluding the IEEPA duties but including the caller Section 122 tariffs — is present 13.7%, according to the Yale Budget Lab. That is beneath the 16% complaint successful effect earlier the Supreme Court's ruling connected Friday, the nonpartisan deliberation vessel said.

Because the alteration is comparatively small, the caller tariffs are apt to person lone a humble interaction connected the economy, Goldman Sachs said successful a probe note, adding that they aren't adjusting their forecasts for ostentation oregon maturation to relationship for the levies. 

Yet the Trump administration's determination to proceed its tariff policies raises broader questions astir whether they are achieving their intended goals, experts said. The president has argued that tariffs will revive U.S. manufacturing and make billions successful caller gross for national coffers.

In 2025, the manufacturing assemblage mislaid 108,000 jobs, according to authorities data.

"What's not happening is the instrumentality of manufacturing to the United States," noted CSIS's Reinsch. Tariffs "are not producing the desired outcome, let's enactment it that way."

"Unprecedented" terrain

Manufacturers that import components utilized to fabricate products astatine U.S. plants person faced higher costs owed to the Trump administration's tariffs, Reinsch added. 

To beryllium sure, U.S. manufacturing is grappling with semipermanent issues beyond tariffs, ranging from an industrywide displacement to automation and fierce planetary competition, including U.S. trading partners who person stepped up subsidies to cardinal industries to offset the higher tariff costs.

The Treasury Department collected $287 billion in tariffs successful 2025, with astir $130 cardinal stemming from the IEEPA tariffs. The Supreme Court ruling whitethorn punctual immoderate businesses to question refunds from the national government, putting that gross successful question. 

The lone happening that seems definite is that the Trump medication is improbable to backmost down from pursuing further tariffs, experts said.

"We're virtually successful unprecedented territory," Grabow said. "The lone happening we cognize for definite is that we person an medication that is undeterred from its usage of tariffs."
