President Trump's temporary 10% global tariff hits its legal expiration date this Friday, but the administration is already building a replacement tariff structure under broader trade authority that carries no built-in sunset.
The tariff, imposed under Section 122 of the Trade Act of 1974, a Cold War-era emergency provision that limits presidential duties to 150 days, runs out on July 24, 2026. Trump invoked the authority hours after the Supreme Court struck down his original tariff program in February, calling the move a first step toward making tariffs "even stronger." Now the clock has run out on that stopgap, and the White House appears ready to swap one legal foundation for another without letting rates fall.
Raymond James analysts wrote in a recent note that they expect the administration to "move ahead with reverse engineering its global reciprocal tariffs," this time under Section 301 of the Trade Act of 1974, a statute that allows the president to investigate and retaliate against countries that violate trade agreements or engage in practices that harm American commerce. Unlike Section 122, Yahoo Finance reported, Section 301 carries no automatic expiration date.
The administration's tariff maneuvering follows a turbulent stretch for federal trade revenue. The 10% Section 122 tariff generated $31.06 billion since it took effect on February 24, Just The News reported. But that figure is dwarfed by the roughly $166 billion the government must refund after the Supreme Court ruled that the International Emergency Economic Powers Act, the legal basis for Trump's earlier, broader tariff regime, does not authorize import duties.
Of that $166 billion, about $121.75 billion had been accepted for processing as of July 10. Tariff revenue peaked at $31.4 billion in a single month last October but turned sharply negative after the court ruling, with a $25.6 billion loss recorded in June alone due to refunds flowing out faster than new duties came in.
That fiscal hole makes the transition to Section 301 more than a legal exercise. It is a revenue question, a trade-policy question, and, with midterm elections approaching, a political one.
The administration has not been waiting for Friday's deadline to act. It launched two major Section 301 investigations designed to justify reimposing broad tariffs on most of America's trading partners.
The first targets forced labor practices. That investigation has already recommended a 10% tariff on goods from 14 nations and the European Union, and a 12.5% tariff on 45 additional countries, including China. The second investigation, initiated in March 2026, focuses on what the U.S. Trade Representative's office calls "structural excess capacity", essentially, government-subsidized overproduction that undercuts American manufacturers. That probe covers China, the EU, and 16 more trading partners and is expected to wrap up later this year.
Treasury Secretary Scott Bessent signaled the administration's timeline months ago. In remarks covered by Fox News, Bessent said tariffs could be restored to previous levels by early July 2026 using Section 301 authority:
"We had a setback at the Supreme Court in terms of the tariff policy. But we will be implementing or conducting Section 301 studies, so the tariffs could be back in place at the previous level by [the] beginning of July."
The administration moved on at least one front ahead of that timeline. On July 15, it imposed a new 25% tariff on nearly all imports from Brazil under Section 301, a rate well above the expiring 10% global levy, and one with no built-in expiration.
Both Trump and Biden used Section 301 during their respective terms. Trump imposed Section 301 tariffs on China during his first term, and many of those duties remain in effect years later. The Biden administration used the same authority. That track record gives the statute a legal pedigree that IEEPA lacked, courts have generally upheld Section 301 actions as a legitimate exercise of trade power.
But trade lawyers warn that using Section 301 to effectively recreate a universal tariff wall is something no president has tried before. Ryan Majerus, a trade lawyer and former trade official who served under both Trump and Biden, told Breitbart plainly:
"They're going to raise the tariff wall again."
Sarah Bianchi, a former U.S. trade official and chief strategist at Evercore ISI, offered a more cautious assessment. Section 301 tariffs "have been pretty legally durable," she said. "But no one has tried to use it to basically put in place universal tariffs. I think there will be legal challenges."
Caleb Petitt of the Independent Institute was more blunt. He acknowledged that Section 301 "does give a fair amount of latitude for what could be considered an unfair practice that could warrant retaliation," but added that "the Trump administration is sure to see legal pushback."
One immediate effect of the tariff transition: the artificial surge in imports that businesses engineered to beat the deadline should subside. Jacob Jensen, director of trade policy at the American Action Forum, noted "a noticeable uptick in U.S. imports compared to last year" driven by companies rushing goods into the country before rates changed.
That front-loading distorts the trade data. Jensen projected the picture will clarify quickly:
"Front-loading is expected to subside after July, with estimated import volumes dropping nearly 5 percent in August and 6 percent in September when compared to 2025."
The Yale Budget Lab calculated that the Section 122 tariffs set an overall effective tariff rate of 11.8% across the U.S. economy. Whether the Section 301 replacements push that number higher depends on which investigations conclude first and at what rates the administration sets the new duties. The forced labor investigation's recommended rates, 10% and 12.5%, suggest a moderate uptick for countries caught in both probes.
Extending Section 122 tariffs beyond 150 days would require an act of Congress. No one expects that to happen. Lawmakers facing midterm voters already frustrated by cost-of-living pressures have little appetite for a vote that could be framed as raising prices on imported goods.
But the administration has structured its approach so that congressional inaction is irrelevant. The Section 301 investigations provide independent presidential authority. The forced labor probe has already produced recommended tariff rates. The excess-capacity investigation is on track to deliver its conclusions before the end of 2026. And the Brazil tariff, announced July 15, demonstrates the administration's willingness to act country by country if broader authority takes time to formalize.
Petitt, the Independent Institute analyst, offered a skeptic's summary of the strategy: "The persistent search for new tariff justifications is a reasonable strategy if the Trump administration is hoping to create hype and draw media attention, but will not be effective at raising revenue, prompting trade deals, or restoring domestic manufacturing."
That assessment may underestimate the administration's resolve. The Supreme Court forced a legal detour in February, not a policy reversal. Five months later, the tariff wall is being rebuilt on different legal ground, and this time, the foundation has no expiration date stamped on it.
Courts struck down the first approach. The administration adapted within hours. Whether you call that persistence or stubbornness depends on where you sit, but the direction of travel has not changed one degree.
