Supreme Court ruling and White House reaction
The U.S. Supreme Court on Friday struck down the administration's use of the International Emergency Economic Powers Act (IEEPA) to impose reciprocal tariffs, issuing a 6-3 decision. Within hours, the White House announced a new tariff measure to take effect on February 24 at 12:01 AM ET, following the IEEPA tariffs that were first introduced by the administration last April.
Structure and timing of the replacement tariff
The administration said the replacement would be a temporary import duty enacted under Section 122 of the Trade Act of 1974: a 150-day levy initially set at 10% on most goods coming into the United States. Over the weekend, President Trump posted that he would increase that rate to 15% effective immediately, though the White House had not formally confirmed the higher rate at the time of the announcement.
Objectives driving the new levy
Officials framed the Section 122 tariff as a tool to curb dollar outflows, encourage domestic manufacturing, support job creation, and strengthen economic and national security. The administration said the measure is intended to address what it described as serious international payment imbalances and a growing U.S. balance-of-payments deficit.
Goods excluded from the temporary tariff
The White House listed a range of exclusions from the Section 122 duty. Excluded categories include:
- Critical minerals and energy products
- Fertilizers not sufficiently produced domestically
- Certain agricultural goods, including beef, tomatoes and oranges
- Pharmaceuticals and their active ingredients
- Certain electronics
- Passenger vehicles and some trucks, buses and related parts
- Aerospace products
- Books, charitable donations and accompanied baggage
- Goods already subject to Section 232 tariffs
- USMCA-compliant goods from Canada and Mexico
- Certain textiles and apparel covered under CAFTA-DR
De minimis shipments and immediate tariff actions
President Trump also reiterated the suspension of duty-free de minimis treatment for low-value imports, meaning low-value shipments that previously qualified for duty-free entry will now be subject to the new temporary duty. In his social media post about raising the tariff, he said the administration would move immediately to the higher rate and would determine legally permissible longer-term tariffs in the coming months.
Administration plans for alternative trade tools
U.S. Trade Representative Jamieson Greer said the White House remains committed to the administration's trade agenda and had warned trading partners and businesses that, if the IEEPA approach was invalidated, it would deploy alternative authorities. Those alternatives are meant to pursue the reciprocal tariff program's underlying goals: reducing the U.S. goods trade deficit, reversing lack of reciprocity by foreign trading partners, and incentivizing reshoring of production.
- Planned actions include new and ongoing investigations under Section 301 of the Trade Act of 1974 to address unfair or discriminatory foreign trade practices.
- The administration also intends to maintain tariffs imposed under Section 232 of the Trade Expansion Act of 1963 and to conclude ongoing investigations.
Economic analysis of tariff replacement scenarios
S&P Global Market Intelligence noted the administration has several statutory alternatives and has publicly committed to keeping tariffs central to trade policy despite the court ruling. The firm said the macroeconomic effect of the court's decision will hinge on whether the administration can replace the invalidated IEEPA levies with tariffs authorized by other statutes.
S&P Global explained that the inflationary effect of, for example, a 15% average tariff does not depend on the specific authorizing statute: a Section 301 tariff that raises the same revenue as an IEEPA tariff would have a comparable effect on aggregate prices. If tariff revenues can be replaced quickly, the firm does not expect a change to its inflation outlook; if they cannot, it expects lower inflation in 2026 and a potentially earlier easing of Federal Reserve policy.
Legal, strategic and supply chain uncertainties
Keith Prather, managing director at Armada Corporate Intelligence, told LM the ruling and the White House's next steps raise several questions: which countries will try to nullify existing agreements, how quickly the administration can complete Section 232 and 301 investigations, and whether tariffs under Section 122 or Section 338 will face successful legal challenges.
Prather suggested the administration may have pre-planned for a 15% Section 122 rate over the weekend because it aligns with negotiated tariff levels for many of the 19 countries that have recent trade agreements. He said the White House could choose to leave those negotiated agreements in place while applying Section 122 duties more broadly, or it could stack short-term tariffs and then pursue longer-term measures through investigations.
Prather also highlighted a practical supply chain dilemma: with the 150-day Section 122 period expiring on July 24, companies must decide whether to accelerate inbound shipments to take advantage of the temporary treatment or maintain normal replenishment cycles and manage inventory and capital costs differently depending on product price sensitivity.
Legal advice and recommendations for importers
Law firm Benesch of Cleveland warned that the court's decision has created immediate uncertainty for supply chains, with billions of dollars in duties now in question and an unclear route for potential refunds. The firm emphasized that not all tariffs are affected—the tariffs imposed under other legal authorities such as Section 232 and Section 301 remain in force.
Benesch urged importers to keep detailed records of customs entries and duties paid in 2025, closely track developments around possible refund procedures, prepare for new tariffs under alternate statutes, monitor any electronic refund processes, and consider filing comments on pending customs changes.
