Days After Indo-U.S. Trade Deal, India Seizes "Sanctioned" Oil Tankers

India seized three oil tankers subject to U.S. sanctions days after New Delhi and Washington announced a major trade agreement, linking maritime enforcement with a period of renewed diplomatic engagement between the two countries.

The tankers were intercepted around 100 nautical miles west of Mumbai, following a coordinated sea-air operation conducted on February 5–6.

The Indian government confirmed in an official statement that it seized three vessels that were involved in the illicit transfer of large volumes of oil and oil-based cargo originating from conflict-ridden regions, but refrained from naming them. The operation was triggered by technology-enabled surveillance that detected suspicious activity within India’s Exclusive Economic Zone. Digital analysis of vessel movements pointed to illicit ship-to-ship oil transfers in international waters, a method used to conceal cargo origin and evade duties.

Coast Guard boarding teams inspected the vessels, examined electronic data and documents, and questioned crew members to establish the sequence of events. Investigators found that the tankers repeatedly changed their identities to avoid detection and were linked to a network operating across multiple countries.

The vessels are expected to be escorted to Mumbai and handed over to Indian Customs and other law enforcement agencies for further legal proceedings. Preliminary findings indicate the vessel owners are based outside India.

The seizures followed the recent announcement of an Indo-U.S. trade agreement that reduced U.S. tariffs on Indian goods to 18% and withdrew an additional 25% duty linked to India’s imports of Russian crude oil. Indian officials have said the agreement includes no explicit commitment to halt Russian oil purchases, stating that energy sourcing remains a commercial decision.
