The White House is racing to replace its expiring 10% global tariffs with a new legal framework after the Supreme Court dismantled the original foundation.
The Trump administration is preparing to replace its expiring 10% global tariffs with Section 301 levies, shifting legal strategy after the Supreme Court in February rejected the president's ability to declare an economic emergency to impose sweeping import taxes. The 10% duties, imposed under Section 122 of the Trade Act of 1974 as a stopgap, were limited to 150 days and expire at midnight Friday.
"The president spoke about this directly yesterday," White House press secretary Karoline Leavitt said Thursday when asked about the tariff transition, adding that U.S. Trade Representative Jamieson Greer would announce the new measures later that day. Leavitt said Trump's patience with congressional inaction on trade policy is "running out."
Greer in March launched a series of Section 301 investigations targeting countries with industrial overcapacity that disadvantages U.S. goods and trade partners that fail to enforce restrictions on imports made with forced labor. Unlike the emergency authority struck down by the court, Section 301 provides a statutory basis for tariffs tied to specific trade practices and does not carry the 150-day time limit. The previous 25% tariff escalation under Section 301 in 2018 reduced bilateral trade flows by roughly $50 billion over 12 months, according to Census Bureau data.
The transition comes as two-thirds of voters say tariffs have raised consumer prices, according to recent polling, and Brent crude briefly topped $100 a barrel Thursday amid Middle East supply disruptions. The S&P 500 dropped 1.1% in early trading, while the Dow Jones Industrial Average fell 415 points, as rising energy costs compounded uncertainty over the tariff regime. The uncertainty is already weighing on business investment, with manufacturing expansion plans stalling as companies await clarity on the final tariff structure.
Legal Pivot and Market Reaction
The Supreme Court's February ruling forced the administration to abandon the emergency-declaration approach it had used since 2025. The 10% global tariffs under Section 122 were always temporary, designed to buy time while the USTR built a more defensible legal case. The Section 301 investigations now provide that path, though they require documented findings of unfair trade practices — a process that could take months to finalize for each targeted country.
Anxious markets have forced repeated retreats from earlier tariff proposals, and exemptions for certain food categories were granted after consumer pushback. The administration's manufacturing push has also met headwinds: rising input costs from tariffs have stalled factory investment plans, undercutting the president's core economic argument that tariffs would revive domestic production.
What Comes Next
The new Section 301 tariffs could replace the expiring duties on a country-by-country basis, with rates potentially matching or exceeding the current 10% level. The investigations cover nations with industrial excesses that disadvantage U.S. producers, a category that includes China and several other major trading partners. Retaliatory measures from affected countries remain a risk, particularly as the Iran war has already disrupted global supply chains and pushed oil above $100 a barrel.
For investors, the key question is whether the administration can sustain elevated tariff levels through the Section 301 process without triggering further market selloffs or consumer backlash. The previous Section 301 tariffs on Chinese goods, imposed during Trump's first term, survived multiple legal challenges and remained in place for years — suggesting the new framework could provide the durability the White House is seeking.
