Supreme Court Strikes Down Trump Tariffs, Leaving Trade Future Uncertain
The Supreme Court’s recent decision to invalidate a series of tariffs imposed by former President Donald Trump has ignited a debate over trade policy and sparked calls for refunds to consumers, and businesses. While the ruling doesn’t eliminate all tariffs, it significantly alters the landscape and introduces new complexities for international commerce.
What Happened with Trump’s Tariffs?
The Supreme Court, in a 6-3 ruling, determined that Trump did not have the authority to impose tariffs using the 1977 International Emergency Economic Powers Act (IEEPA) by declaring a national emergency. This effectively overturned the sweeping “reciprocal” tariffs on imports from countries like Canada, China, and Mexico, as well as additional levies linked to the flow of fentanyl into the U.S. [SCOTUSblog]
Can Trump Still Impose Tariffs?
Despite the ruling, the President still has avenues to impose tariffs. Tariffs imposed under Section 232 of the 1962 Trade Expansion Act, based on national security concerns, remain in place. These include tariffs on steel, aluminum, and automobiles. [CFR] tariffs imposed under Section 301 of the Trade Act of 1974, targeting unfair trade practices (particularly those on Chinese imports), are as well still active.
The Trump Administration is planning new investigations under both Section 232 and Section 301, potentially covering batteries, cast iron, electrical grid equipment, telecom equipment, plastics, industrial chemicals, and more. [CFR]
Trump has invoked Section 122 of the 1974 Trade Act to impose a new 10% global tariff, which he intends to raise to 15%. This tariff is capped at 15% and can only be in effect for 150 days. [BBC News]
Will Consumers Receive Tariff Refunds?
Following the Supreme Court’s decision, Democrats are pushing for refunds of the roughly $175 billion collected from the invalidated tariffs. [CFR] Senate Democrats have proposed legislation to require full refunds with interest to businesses that paid the duties, with the possibility of passing savings onto consumers. Some Democrats are even advocating for direct refunds to households. [CFR]
Yet, Trump has indicated he has no immediate plans to issue refunds, suggesting the matter could be tied up in court for years. [BBC News] Justice Brett Kavanaugh also acknowledged the potential “mess” involved in processing billions of dollars in refunds. [SCOTUSblog]
How Will Prices Be Affected?
The Yale Budget Lab estimates the Supreme Court ruling reduced the average effective tariff rate from 17% to 9%. [CFR] However, the new 10% (and potentially 15%) tariff imposed under Section 122 could offset some of those savings. U.S. Customs and Border Protection stopped collecting the emergency tariffs after February 20, 2026.
Impact on Trade Deals
The ruling has created uncertainty for trade agreements. Countries that had negotiated lower tariff rates with the U.S. May now face higher duties. The U.K., Japan, South Korea, and several EU nations could notice increased tariffs. [CFR]
The EU has paused ratification of its trade deal with the U.S., seeking clarification on whether the agreement will be honored. [CFR] The U.K. Is also seeking assurances that its preferential trade terms will remain in effect. [CFR]
Several countries had pledged investments to the U.S. In exchange for lower tariffs, and the future of those commitments is now in question. [CFR] Trump has warned countries against backing out of trade deals or pledged investments. [CFR]
