Trump Hits Back: New 15% Global Tariff After SC Voids Duties

Introduction: A Swift Reversal in US Trade Policy

In a dramatic turn of events for global trade, the United States has implemented a new global tariff after the US Supreme Court struck down President Donald Trump's previous sweeping import duties. Within hours of the court's decision, President Trump retaliated by signing an executive order for a 10% global tariff, which he subsequently raised to 15%. This new levy, effective February 24, 2026, is based on a different legal authority and introduces a fresh wave of uncertainty for trading partners like India, altering existing and negotiated trade frameworks.

The Supreme Court's Landmark Ruling

The catalyst for this policy shift was a significant 6-3 ruling by the US Supreme Court, which declared President Trump's tariffs imposed under the International Emergency Economic Powers Act (IEEPA) illegal. The court determined that the 1977 emergency law did not grant the president the authority to levy such broad tariffs without explicit approval from Congress. This decision represented a major check on presidential power and immediately invalidated a cornerstone of Trump's protectionist trade agenda, leaving a significant question mark over the $133 billion in duties already collected under this authority.

Trump's Immediate Countermeasure

Refusing to accept the judicial setback, President Trump acted swiftly to keep his trade barriers in place. Hours after the ruling, he announced a new 10% global tariff via an executive order. The following day, he escalated the measure, increasing the rate to the maximum allowed 15%. In a social media post, Trump stated he was raising the tariff to the "fully allowed, and legally tested, 15% level," targeting countries he claimed had been taking advantage of the U.S. for decades. This rapid response underscored his administration's commitment to using tariffs as a primary economic tool, regardless of legal challenges.

A New Legal Basis: Section 122

To bypass the limitations cited by the Supreme Court, the Trump administration invoked Section 122 of the Trade Act of 1974. This rarely used provision allows the president to impose a temporary import surcharge of up to 15% for a maximum of 150 days to address a "large and serious" balance of payments deficit. Unlike the IEEPA, this authority does not require prior congressional approval for its initial implementation. However, any extension beyond the 150-day period must be legislatively approved by Congress, setting a new deadline for the administration's trade strategy.

Impact on India and Global Trade

The new tariff has created considerable confusion for US trading partners, particularly India. Just weeks prior, Washington and New Delhi had reportedly agreed on an interim trade framework that would have set the tariff rate at 18%. While President Trump initially stated that "nothing changes" for the India trade deal, the White House later clarified that the new 15% global tariff would apply to all countries temporarily, superseding previously negotiated rates. This means Indian goods, effective February 24, will face the new 15% levy, disrupting recent agreements and forcing exporters to adapt to yet another shift in US trade policy.

The Fate of Collected Tariffs

A major unresolved issue from the Supreme Court's ruling is the status of the estimated $133 billion in tariffs collected under the now-voided IEEPA. The court's decision did not provide a clear path for refunds, and the US Customs and Border Protection (CBP) agency offered no immediate information on the matter. Economic experts and businesses anticipate a "prolonged period of uncertainty" and a complex, lengthy legal battle for importers seeking to reclaim these funds. The process could take several years to resolve through litigation, leaving many businesses in financial limbo.

Summary of US Tariff Changes

Broader Economic Implications

The rapid sequence of events has injected further volatility into global markets. Economists predict that the uncertainty will disrupt supply chains and investment decisions as businesses struggle to navigate the shifting legal landscape. The administration's pivot to Section 122 is seen as a temporary fix, and the 150-day limit puts pressure on the White House to either find another legal avenue or negotiate a more permanent solution with Congress. Meanwhile, other US tariffs, such as those imposed under Section 232 (national security) and Section 301 (unfair trade practices), remain unaffected by the Supreme Court's ruling.

Conclusion: An Unsettled Trade Environment

The clash between the White House and the Supreme Court has fundamentally reshaped the US tariff regime. While the court reasserted congressional authority over broad trade policy, President Trump's immediate use of an alternative statute ensures his protectionist measures continue for now. For India and other global partners, the result is a lower but still significant tariff and, more importantly, a continuation of the trade unpredictability that has characterized the past year. All eyes are now on the 150-day deadline, which will determine whether these temporary measures become a more permanent feature of global trade or if Congress will intervene.
