Billionaire Mukesh Ambani-led Reliance Industries-- Indias largest oil refiner-- has said it will tweak its refinery operations to comply with the latest round of sanctions imposed by the United States and other Western countries on Russian oil imports. In a statement on Friday the oil-to-telecom conglomerate said it remained fully committed to maintaining adherence to applicable sanctions and regulatory frameworks. Why Reliance plans to tweak refinery operations? Reliance Industries-- Indias most valued domestic firm-- also said it is assessing the implications of restrictions announced by the European Union the United Kingdom and the United States on crude oil imports from Russia and the export of refined products to Europe. “We will comply with the EU’s guidelines on the import of refined products into Europe said a Reliance spokesperson adding that the conglomerate will tweak its refinery operations to meet the latest sanctions compliance requirements. On October 22 the Trump administration imposed sanctions in Rosneft and Lukoil two of Russias largest crude oil producers. The latest punitive move by Washington bars all US entities and individuals from conducting business with the sanctioned Russian firms while non-US companies could invite penalties if found dealing with them or their subsidiaries. According to the US Treasury Department all existing transactions involving Rosneft and Lukoil must be wound down by November 21. How US sanctions impact Reliances oil business? The latest US sanctions on Russian oil is a major setback for India and Reliance as Russian oil imports account for nearly a third of Indias total crude imports with the Mukesh Ambani-led company being the single largest buyer of Russian crude in the country. According to official data India imported around 1.7 million barrels per day (mbd) of crude from Russia in 2025 of which approximately 1.2 mbd came directly from Rosneft and Lukoil. A major portion of these purchases were made by private refiners Reliance Industries Ltd and Nayara Energy with smaller allocations to state-owned refiners. Russian crude flows are expected to remain in the 1.6–1.8 mbd range until November 21 but direct volumes from Rosneft and Lukoil are likely to decline thereafter as Indian refiners seek to avoid any risk of US sanctions said Sumit Ritolia Lead Research Analyst (Refining and Modelling) at Kpler PTI reported. Reliance begins diversifying oil imports Earlier this week reports emerged that Mukesh Ambanis Reliance Industries has begun diversifying its oil purchases and procured at least 2.5 million barrels of crude oil from Middle Eastern suppliers. According to a Bloomberg report Reliance which owns the worlds largest refinery in Gujarats Jamnagar purchased crudes from Iraqs Basrah Medium Al- Shaheen and Qatar Land among other suppliers in the Middle East and is likely to place larger orders in coming days. The surge in spot oil purchases by Reliance which has been the single largest buyer of Russian crude in India comes following Donald Trumps alleged phone call with Narendra Modi during which the Indian Prime Minister allegedly agreed to halt Russian oil imports in a gradual manner.
