The Office of the U.S. Trade Representative opened hearings this week in two sweeping Section 301 investigations that the administration expects will produce a fresh round of import taxes, a move designed to keep tariff revenue flowing after the Supreme Court shut down President Donald Trump's preferred trade tool in February.
The hearings mark the clearest signal yet that the White House intends to rebuild its tariff wall on firmer legal ground. One investigation covers 60 economies responsible for 99 percent of U.S. imports. The other targets 16 trading partners, including China, the European Union, and Japan, that together account for roughly 70 percent of imports, the Associated Press reported.
The stakes are enormous. The original tariffs, imposed under the 1977 International Emergency Economic Powers Act, brought in $166 billion before the Court ruled on February 20 that Trump had overstepped his authority. Lost revenue had been projected to hit $1.6 trillion over the next decade. Now the federal government must refund money to importers who paid those levies.
Section 301 of the Trade Act of 1974 authorizes tariffs and other sanctions against countries found to engage in "unjustifiable," "unreasonable," or "discriminatory" trade practices. The administration is running two parallel tracks under that statute: a Tuesday-and-Wednesday hearing on whether 60 economies do enough to prohibit trade in goods created by forced labor, and hearings next week on whether 16 trading partners are overproducing goods at the expense of American industry.
The timeline is compressed. When Trump used Section 301 against China during his first term, the investigation and public-comment period took nearly a year. If the new tariffs replace the expiring Section 122 levies before the July 24 deadline, the entire process will have taken less than half that long.
Kenya Davis, a partner at the law firm Boies Schiller Flexner, questioned the pace:
"It's such a short timeframe. It's so condensed that it doesn't make a lot of sense that they can do it that quickly."
That criticism deserves a fair hearing. But speed alone does not equal illegitimacy. The administration faces a hard deadline, Section 122 tariffs expire July 24, and the underlying trade grievances are not new. Forced labor in global supply chains and state-subsidized overproduction, particularly from Beijing, have been documented for years. The question is not whether the problems exist but whether the legal process can withstand judicial scrutiny.
The Supreme Court's February 20 ruling did not say tariffs themselves are unconstitutional. It said the president could not use IEEPA, a law designed for genuine national emergencies, as a blank-check tariff authority. That distinction matters. As Trump responded to the ruling with a new 10 percent global levy under Section 122, the administration was already preparing the longer-term Section 301 route.
Scott Lincicome of the Cato Institute's Center for Trade Policy Studies put it bluntly:
"One of the reasons Trump used IEEPA is because it was just a complete blank slate, a little tariff switch in the Oval Office that Trump could flip on and off anytime he wants; he wakes up in the morning and he doesn't like a Canadian television commercial, he flips the switch... You really can't do that with 301."
That is precisely the point. Section 301 requires investigation, hearings, and findings, the kind of process that gives tariffs a stronger legal foundation. Trump's first-term Section 301 tariffs against China withstood legal challenges. The administration is betting the same framework will hold again, even at an accelerated pace.
Two days after the Supreme Court decision, the administration imposed 10 percent Section 122 tariffs on imports, a temporary bridge. Section 122 allows the president to impose global tariffs as high as 15 percent for up to 150 days. Trump said he would raise the levies to the maximum but has not done so. Congress could extend those tariffs, though no such action has materialized.
The administration later raised the global tariff to 15 percent in a separate move, signaling that it views tariff revenue as non-negotiable fiscal policy, not a temporary bargaining chip.
Treasury Secretary Scott Bessent has proclaimed that the government will replace its original tariff revenues with new import taxes, including those under Section 301. The president himself said the new tariffs "are going to get us more money."
Lincicome was skeptical that the investigations would be anything other than a foregone conclusion:
"If you believe the Treasury secretary and the president, then the cake is already baked. These investigations will result in tariffs that approximate what the Supreme Court overruled in February."
Critics will argue the administration is dressing up the same tariffs in different legal clothing. That charge is not frivolous. But it also misses what the Supreme Court actually said. The justices did not reject tariffs as a policy tool. They rejected one specific legal mechanism, IEEPA, as the wrong vehicle. Using Section 301, which Congress explicitly designed for trade disputes, is a direct response to the Court's reasoning.
Joyce Adetutu, a trade lawyer and partner at Vinson & Elkins, suggested courts might accept the new approach:
"Even if it is a veiled, or less-than-veiled, attempt to reinitiate the IEEPA tariffs, he still has the cover of the process itself."
That legal cover is not trivial. Section 301 tariffs expire after four years but can be extended, giving the administration a durable framework rather than the 150-day window of Section 122. If the hearings produce credible findings on forced labor and overproduction, future legal challenges will face a much steeper climb.
U.S. Trade Representative Jamieson Greer framed the first investigation in moral terms when he announced it in March:
"For too long, American workers and firms have been forced to compete against foreign producers who may have an artificial cost advantage gained from the scourge of forced labor."
The investigation spans 60 economies, from Nigeria to Norway, and asks whether those nations do enough to prohibit trade in goods made by forced labor. It is a question that should unite left and right, though it rarely does when tariffs are the proposed remedy.
Greer has insisted he will not prejudge the investigations. Whether that assurance holds will depend on the quality of the findings and the transparency of the process. The Supreme Court has shown it is willing to act decisively when it believes the executive branch has overreached. The administration would be wise to build an airtight record.
The overproduction hearings next week will target 16 trading partners, including the EU and Japan, allies the administration also pressured with IEEPA tariff threats during earlier trade negotiations with South Korea and others. The scope is broad. The Erica York figure from the Tax Foundation, that those 16 partners account for 70 percent of U.S. imports, underscores just how wide the net is being cast.
July 24 is the hard deadline. If Section 301 tariffs are not ready by then, the Section 122 stopgap expires and the administration loses its tariff revenue stream unless Congress acts. That creates enormous pressure to move fast, and enormous incentive for opponents to argue the process was rushed.
The administration's position is straightforward: American workers deserve protection from foreign producers who cheat, and the government needs the revenue. The legal vehicle has changed. The policy aim has not.
When the Supreme Court tells a president he used the wrong law, the right response is to use the right one. That is what the administration is doing. Whether it does so carefully enough to survive the next legal challenge will determine whether this tariff wall stands or falls like the last one.
