For India, the US Supreme Court ruling has immediate implications tied to a recent bilateral trade framework. Earlier in 2026, the US had reduced punitive tariffs on Indian imports from as high as 50% (linked to issues like Russian oil purchases) to 18% as part of an interim deal. The Supreme Court's decision removed the legal foundation for those IEEPA-based tariffs, potentially reverting duties on a substantial portion of Indian exports to the standard Most Favoured Nation (MFN) rate of around 3.5%. Analysts noted this could free up to 55% of India's US-bound exports from elevated duties, providing short-term relief to sectors like textiles, pharmaceuticals, and agriculture by lowering costs and enhancing competitiveness in the American market.

In swift response, President Trump announced a new 10% global tariff on imports from all countries, including India, invoking Section 122 of the Trade Act of 1974. This temporary measure, effective from February 24 for up to 150 days, addresses balance-of-payments concerns and serves as a bridge while the administration explores other avenues. The White House clarified that countries with prior deals, such as India, would face this 10% rate instead of negotiated ones, though existing concessions from those agreements are expected to remain in place. This shift means India's effective tariff burden drops from the prior 18% but rises above the potential MFN baseline, creating a mixed outcome for exporters.

What remains unchanged are tariffs imposed under other statutory authorities, which the ruling left intact. These include Section 232 national security duties on steel, aluminum, and other products, as well as Section 301 levies targeting unfair trade practices, particularly against China but potentially expandable. For India, sector-specific impacts—such as any ongoing or future investigations—could persist or emerge independently of the IEEPA decision. The administration has signaled intentions to pursue additional probes under these laws, suggesting tariffs will continue as a core tool in US trade policy despite the setback.

Overall, the Supreme Court's ruling curbs broad presidential emergency powers on tariffs but does not dismantle the protectionist framework entirely. For India, it introduces temporary relief and uncertainty, with the new 10% global levy offering a lower rate than recent highs but higher than pre-escalation norms. Bilateral trade talks may need reassessment amid this flux, as both nations navigate ongoing negotiations, potential refunds for overpaid duties, and the broader global trade landscape reshaped by the decision.
