A clause in the February 6 India-US interim trade understanding allowing either side to modify commitments if tariffs change has come into focus after Washington altered its import duty framework following a court setback.The development follows a ruling by the US Supreme Court striking down sweeping tariffs imposed under emergency economic powers, prompting US President Donald Trump to announce a fresh, temporary global levy.Under the new order, the US will impose a uniform 10 per cent ad valorem duty on most imports for 150 days beginning February 24. India, which had faced tariffs of up to 18 per cent earlier, now falls under the lower flat rate.The February 6 joint statement had specified that in the event of any change to the agreed tariffs by either country, the other may correspondingly modify its commitments — a provision sources say effectively reopens negotiating space.The Ministry of Commerce & Industry too said it was assessing the implications of the US measures. “We have noted the US Supreme Court judgement on tariffs yesterday. President Trump has also addressed a press conference in that regard. Some steps have been announced by the US administration. We are studying all these developments for their implications,” it said.Sources indicated the tariff revision does not by itself necessitate any counter-measures, but it certainly creates a technical provision under the interim arrangement allowing either side to review the tariff assumptions on which specific concessions were structured.For India, while the immediate headline duty has fallen to 10 per cent, exporters and negotiators will now evaluate how the changed tariff baseline affects the commitments exchanged in the bilateral interim agreement.
