Hours after the Supreme Court gutted his emergency tariff regime, President Trump fired back with a new weapon pulled from a different shelf. On Friday evening, Trump issued a proclamation invoking Section 122 of the Trade Act of 1974, slapping a fifteen percent import surcharge on most goods entering the United States. The surcharge takes effect today, February 24.
The move came after a 6–3 ruling in which Chief Justice John Roberts wrote for the majority that Trump had exceeded his authority under the International Emergency Economic Powers Act, Breitbart News reported. Under IEEPA, tariffs in some cases had climbed as high as fifty percent. The Court said no. Trump said: fine, watch this.
Section 122 permits the president to impose an import surcharge when the country faces "fundamental international payments problems" that are "large and serious." Trump's proclamation cited the trade deficit and related economic indicators as justification, then initially set the rate at ten percent before cranking it to the statutory maximum of fifteen percent.
That word, "maximum," matters. Trump didn't test the waters. He walked straight to the ceiling.
The surcharge carries a built-in clock. Absent an act of Congress, it expires after 150 days, putting the deadline at July 24. The proclamation described the surcharge as "required" and noted it would apply "in addition" to existing duties. On social media, Trump said his administration had conducted a "thorough, detailed, and complete review" and announced further action ahead: "The Trump Administration will determine and issue the new and legally permissible Tariffs."
He indicated that it would happen within "the next short number of months."
The surcharge casts a wide net, but it isn't indiscriminate. Exemptions cover a significant list of categories:
Many of these exemptions trace back to the original "Liberation Day" executive order of April 2, 2025, which excluded several categories from reciprocal tariffs. The administration later expanded the exemption list. The new proclamation preserves that framework, applying the surcharge broadly while shielding supply chains where disruption would inflict the most immediate domestic pain.
The Tax Foundation estimates the surcharge applies to roughly $1.2 trillion in annual imports, about 34 percent of total U.S. goods imports.
Before the Supreme Court ruling, the effective tariff rate stood at approximately sixteen percent, according to Yale's Budget Lab. The ruling cratered that to about 9.1 percent. The fifteen percent surcharge pushes it back up to an estimated 13.7 percent while in effect.
But here's the catch built into the 150-day limit: if the surcharge expires in July without congressional action, the Budget Lab estimates the effective rate slides back to around 9.1 percent by year's end.
The Tax Foundation's estimates tell a similar story from a different angle. Under the pre-ruling IEEPA regime, the applied tariff rate sat at approximately 13.8 percent. At the fifteen percent surcharge, the applied rate reaches about 12.1 percent. At ten percent, it would have been roughly 10.3 percent. After expiration, it drops to an estimated 6.7 percent.
For full-year 2026, the Tax Foundation projects an effective tariff rate of about 6.0 percent with 150 days of the fifteen percent surcharge, compared with roughly 10 percent under the regime the Court just dismantled.
Revenue projections sharpen the picture further:
That $33 billion in net revenue isn't nothing. It's also not the full weight of the IEEPA regime. This is a bridge, not a replacement.
The conventional playbook after a Supreme Court loss is to regroup, consult lawyers, issue a measured statement expressing respect for the judiciary, and quietly scale back ambitions. Trump did none of that. Within hours of the ruling, he had identified an alternative legal authority, set the rate at maximum, and announced on social media that more was coming.
The 6–3 ruling itself deserves scrutiny beyond the headline. The Court held that IEEPA did not grant the president authority to impose tariffs. That's a legitimate constitutional boundary. But it did nothing to diminish the underlying economic reality that drove the tariffs in the first place: a persistent, structural trade deficit that has hollowed out American manufacturing and left the country dependent on foreign supply chains for critical goods.
The Supreme Court can rule on statutory authority. It cannot rule away a $1.2 trillion import flow or the strategic vulnerabilities it creates.
The real question now is what happens between today and July 24. The surcharge buys time, but time for what?
Trump's social media statement signals the answer: the administration intends to construct a new tariff framework on firmer legal ground. The 150-day window functions as both a revenue bridge and a negotiating lever. Trading partners who expected the Supreme Court ruling to restore the pre-Trump status quo just learned otherwise. The surcharge tells them the pressure doesn't vanish because one legal theory failed.
Congress, too, faces a decision. The surcharge expires automatically without legislative action. If Republicans want to preserve or expand the tariff architecture, they'll need to move. If they don't, the effective rate falls to levels well below what the administration maintained under IEEPA.
That makes this as much a test of congressional will as presidential creativity.
The left will frame this as a president defying the Court. That framing collapses on contact with the facts. Trump complied with the ruling. He did not reimpose IEEPA tariffs. He invoked a different statute with independent legal authority, one Congress passed specifically to address the kind of trade imbalances the administration has identified.
There is nothing constitutionally irregular about a president using an alternative legal pathway after one is foreclosed. Presidents do it routinely in immigration, environmental regulation, and national security. The only difference here is that Trump did it fast, did it publicly, and did it at maximum intensity.
Speed, in this case, is the message. So is the rate.
The Court drew a line. Trump found another door. The surcharge takes effect today, the clock is running, and the next move belongs to Congress.
