Trump Imposes 10% Global Tariff After Supreme Court Setback
President Donald Trump has announced a sweeping new 10 percent tariff on nearly all foreign goods entering the United States. The move comes just hours after the US Supreme Court struck down several of his earlier tariffs, dealing a major legal blow to his trade strategy.
The new tariff, ordered through a Friday directive from the Oval Office, will take effect on February 24 at 12:01 a.m. Washington time, according to a White House fact sheet.
Trump described the action as decisive and immediate, stating on social media that he had signed a “Global 10% Tariff on all Countries,” emphasizing that it would be effective almost at once.
The announcement signals that despite legal setbacks, Trump remains committed to reshaping America’s trade relationships.
Why the Supreme Court Blocked Trump’s Previous Tariffs
Earlier that same day, the US Supreme Court issued a 6-3 ruling against Trump’s earlier tariffs. The Court found that his use of emergency powers under the International Emergency Economic Powers Act was unlawful for imposing broad “reciprocal” tariffs on dozens of trading partners.
The Emergency Law at the Center of the Dispute
Last April, Trump relied on the International Emergency Economic Powers Act to justify tariffs ranging from 10 percent to 50 percent on multiple countries. He argued that trade imbalances and issues such as fentanyl trafficking justified emergency action.
The Supreme Court disagreed. The justices ruled that the decades-old emergency law could not be used in this way to impose sweeping trade duties.
The decision invalidated tariffs not only on various global trading partners but also on goods from Canada, Mexico, and China that had been targeted under the same emergency authority. It also cast doubt on similar tariffs affecting Brazil and India.
The ruling left a major gap in Trump’s trade framework, prompting the immediate rollout of the new 10 percent global tariff.
How the New 10% Global Tariff Works
Invoking Section 122 of the Trade Act of 1974
To implement the new measure, Trump is using Section 122 of the Trade Act of 1974. This provision gives the president unilateral authority to impose temporary tariffs to address balance-of-payments problems or protect the US dollar.
However, there is a key limitation: tariffs under Section 122 can only remain in effect for 150 days unless Congress approves an extension.
That creates political uncertainty. Democrats and some Republicans have already shown resistance to parts of Trump’s trade agenda. Any attempt to extend the tariffs beyond the 150-day window would likely spark intense debate on Capitol Hill.
What Stays and What Changes
Alongside the new 10 percent baseline tariff, Trump said existing import taxes under Section 301 and Section 232 will remain in place.
Section 232 tariffs typically focus on national security concerns, such as duties on steel and aluminum. Section 301 tariffs target unfair trade practices and require detailed country-specific investigations.
The White House signaled that further trade investigations are on the way, suggesting that the 10 percent tariff could eventually be replaced or supplemented by more targeted measures.
New Trade Investigations on the Horizon
The Office of the US Trade Representative has been directed to launch fresh investigations under Section 301 authority.
Unlike emergency tariffs, Section 301 actions require formal inquiries. These include hearings and opportunities for input from affected companies or countries. Officials must determine that a trading partner violated a trade agreement or engaged in practices that harm US trade.
According to US Trade Representative Jamieson Greer, the new investigations are expected to focus on major trading partners and a wide range of concerns. These may include industrial overcapacity, forced labor, pharmaceutical pricing practices, digital services taxes, discrimination against US technology firms, and environmental issues related to seafood and agriculture.
Greer described the process as moving on an accelerated timeline, even as ongoing probes into Brazil and China continue.
Trump has also suggested he is considering additional tariffs on foreign automobiles, potentially ranging from 15 percent to 30 percent.
What This Means for US Tariff Rates
Bloomberg Economics estimates that the 10 percent global tariff could significantly change the overall US effective tariff rate.
If fully implemented, the average effective tariff rate could rise to 16.5 percent from 13.6 percent. However, if certain exemptions remain in place, the rate could drop to around 11.4 percent instead.
The final impact depends heavily on which goods are excluded.
Key Exemptions
Some exemptions from earlier tariffs will remain.
Goods compliant with the United States-Mexico-Canada Agreement will not be subject to the new 10 percent tariff. Certain agricultural products also retain exemptions consistent with previous policies.
The White House says it aims for continuity to avoid sudden disruptions in critical sectors.
Political Tensions Inside Congress
The new tariff plan is already drawing criticism from both parties.
Representative Don Bacon, a Republican from Nebraska and longtime tariff critic, warned that continued reliance on executive authority for trade policy could lead to more Republicans voting against Trump’s agenda.
Bacon recently joined House Democrats in voting to overturn tariffs on Canada. He indicated that additional tariff measures could further strain party unity.
If Congress must vote to extend the Section 122 tariffs after 150 days, Trump may face a divided legislature.
The Big Question: What About Refunds?
The Supreme Court ruling has raised another critical issue: refunds.
More than 1,500 companies had filed lawsuits in trade court in anticipation of the decision. Many are now waiting to see whether they are entitled to refunds on tariffs already paid.
The justices did not directly address whether importers should receive their money back. That decision will now fall to a lower court.
Refunds could total as much as 170 billion dollars, which is more than half of the total revenue generated by Trump’s tariffs so far.
Trump has criticized the Supreme Court for not offering guidance on how refunds should be handled, warning that prolonged court battles could follow.
Despite this uncertainty, Treasury Secretary Scott Bessent has said that overall tariff revenue in 2026 is expected to remain virtually unchanged. He argued that the use of Section 122 authority, along with potential increases under Sections 232 and 301, would offset the impact of the Court’s ruling.
A Turning Point for US Trade Policy
The introduction of a global 10 percent tariff marks a pivotal moment in US trade policy.
On one hand, it shows Trump’s determination to push forward with his trade agenda despite judicial pushback. On the other hand, it highlights the legal and political limits of executive power in shaping international commerce.
Businesses now face a period of uncertainty. Importers must prepare for higher costs, possible future investigations, and ongoing legal disputes over past tariffs. Consumers could also feel the effects if companies pass increased import costs along through higher prices.
As the new tariff takes effect on February 24, attention will shift to Congress and the courts. Will lawmakers extend the measure beyond 150 days? Will companies win refunds? And will new investigations lead to even higher country-specific duties?
One thing is clear: the battle over US trade policy is far from over. With legal, political, and economic stakes rising, the coming months could redefine how America engages with the global economy.
