WASHINGTON — A fire-breathing President Trump vowed Friday that the Supreme Court’s ruling striking down his use of emergency powers to impose worldwide tariffs would not stop him. 

The president, repeatedly slamming the six justices on the court who sided against him, announced he was imposing a 10% global tariff under different powers.

He also said further levies he plans to impose would bring in even more money than the $175 billion netted from his “Liberation Day” and fentanyl tariffs. 

“Foreign countries that have been ripping us off for years are ecstatic. They’re so happy, and they’re dancing in the streets, but they won’t be dancing for long — that I can assure you,” Trump vowed, after accusing justices of being “swayed by foreign interests.”

“Other alternatives will now be used to replace the ones that the court incorrectly rejected,” he proclaimed. “We have alternatives, great alternatives — could be more money.” 

The Supreme Court ruled 6-3 that Trump exceeded his authority under the International Emergency Economic Powers Act of 1977 (IEEPA), which allows presidents to regulate commerce during national emergencies, to impose tariffs to address trade imbalances and halt fentanyl smuggling.

The ruling knocked down Trump’s 10% baseline tariff on most countries and higher rates imposed on nations with which the US has big trade deficits — as well as fentanyl-specific tariffs on China, Canada and Mexico, imposed after 330,000 Americans died from the synthetic opioid over five years.

US Trade Representative Jamieson Greer, appearing alongside Trump, said “we have a lot of tools out there” to replace the duties the court struck down.

The tariff windfall — which Trump has repeatedly boasted about — went to reducing the federal deficit, and the president also repeatedly teased the possibility of $2,000 tariff rebate checks for taxpayers.

But that haul — up to $200 billion — could now be subject to refunds, though Trump demurred on whether he’ll pay it back. The Supreme Court was silent on that subject.

“I guess it has to get litigated for the next two years,” he quipped.

“Wouldn’t you think they would have put one sentence in there saying that keep the money or don’t keep the money?”

The administration’s plan to resurrect most tariffs means that consumers aren’t likely to see lower prices for imported goods. The Yale Budget Lab said the demise of the IEEPA levies could save households an average of $900 this year in lower prices of imported goods.

Stock markets rose after the Supreme Court’s ruling, which the Trump administration had been bracing for for months. The tech-heavy NASDAQ closed up 0.9%. 

Yields on US government bonds rose slightly and the US dollar fell — after investors became anxious about the possibility of surging deficits. 

The alternate powers that Trump cited on Friday do give him leeway, but they have more drawbacks.

Section 122 of the Trade Act of 1974 allows Trump to unilaterally impose up to 15% tariffs to remedy balance-of-payments issues or prevent “imminent and significant” depreciation of the dollar for up to five months without congressional approval.

Section 301 of the same law allows Greer to impose tariffs on countries with economic policies that are discriminatory against the US or in violation of trade agreements. These duties expire after four years unless a continuation is sought.

The USTR is obligated to first conduct an investigation, which includes consulting with the foreign government and soliciting public comment — a process Trump said will take “about five months.”

Greer said Section 301 tariffs “are incredibly legally durable” and would be used to “address unfair trading practices that have led to our huge trade deficit.

“So you can look forward in the coming days and weeks to seeing all of that come out, and we’re going to keep continuity in the program,” Greer said.

In addition to the two legal authorities cited by Trump, a number of other laws could pave the way for the restoration of tariffs.

Most major trading partners negotiated pending trade deals with Trump last year to reduce his threat of even higher tariffs — and the president said he expects many of those pacts to remain intact.

“Some of them stand. Many of them stand. Some of them won’t, and they’ll be replaced,” Trump told reporters.

Trump said that he had just met with Vietnamese officials who told him they thought the ruling “means you’re allowed to charge us more tariffs than before.”

Many of Trump’s duties were not impacted by the Supreme Court ruling, including 50% tariffs on steel, aluminum and copper.

Trump’s 25% tariffs on most foreign-made vehicles also was adopted under a different legal authority and remain in effect.

The car levies give Trump leverage to keep intact major pending trade deals due to the fact that he subsequently agreed to lower the vehicle tariff to 15% for Japan, South Korea, and the European Union — and 10% on shipments from the UK.

The Supreme Court ruling sets in motion the anticipated return of the $175 billion in revenue collected over the past year — a process that dissenting Justice Brett Kavanaugh noted would be a “mess.”

Trump tore into the justices who ruled against him as “unpatriotic and disloyal to our Constitution,” but admitted the decision brings a level of “certainty” to his economic policy.

He said that despite his legal defeat, “I have very effectively utilized tariffs over the past year to make America great again.”

The president vividly boasted of support for his policies, saying “a very powerful, strong man” in the steel business told him, “Sir, I want to kiss you so badly.”

“I said, ‘Why?’ He said because we were down to working one hour a week, and then you came in and imposed tariffs, and all of that foreign junk that they were dropping into our country stopped,” Trump said.

The president said “we’re going to keep it going the same way.”

“I think you’re going to see the country get much stronger because of it,” the president declared. “In the end, I think we’ll take in more money than we’ve taken in before.”
