In a dramatic turn in global trade policy, the U.S. Supreme Court struck down key portions of President Donald Trump’s sweeping tariff regime, ruling that the administration overstepped its authority by imposing broad import duties without clear congressional approval. The decision has triggered an immediate policy pivot — including a temporary reduction of tariffs on Indian exports to 10% starting February 24 for a 150-day period.

The Legal Turning Point

The court’s ruling centered on the use of the International Emergency Economic Powers Act (IEEPA), a 1977 statute designed to address extraordinary economic threats. While the law allows emergency trade restrictions, the majority held that it does not explicitly authorize the president to levy sweeping tariffs — a power constitutionally vested in Congress.

This landmark judgment not only limits executive authority on trade but also sets a precedent that could reshape future U.S. trade policy.

Trump’s Rapid Response

Within hours of the ruling, the White House announced a new 10% global tariff under Section 122 of the Trade Act of 1974 — a provision allowing temporary import surcharges for up to 150 days to address trade imbalances.

Effective February 24, the revised measure replaces earlier tariffs that, in some cases, reached 25–50% on certain Indian goods. While the new 10% duty is significantly lower, it still imposes additional costs on exporters.

What It Means for India

For India, the shift brings partial relief. Sectors such as textiles, auto components, engineering goods, and select manufactured exports had been under pressure from elevated U.S. tariffs. A uniform 10% levy restores some competitiveness compared to earlier rates, though it does not eliminate trade friction.

Indian trade officials are expected to closely monitor developments, especially given that the surcharge is temporary and subject to congressional review. Industry leaders in India view the move as a short-term stabilization rather than a permanent solution.

Broader Global Impact

Markets reacted cautiously to the legal setback and the swift tariff recalibration. The ruling underscores institutional checks within the U.S. system and signals to global partners that trade policy may face tighter judicial scrutiny going forward.

For now, the 150-day window provides breathing room — but uncertainty remains over whether Congress will step in, whether further legal challenges will emerge, or whether new negotiations could redefine trade relationships.
