Indian Oil Corp (IOC), the country's top refiner by capacity, is seeking to buy high-sulphur oil through spot tenders, its first sour crude import tenders since March 2022, trade sources said on Thursday.

India is now staring at the possibility of an oil shock after the U.S. decided to implement sweeping sanctions on Russia's oil industry.

It is India's first tender for sour crude imports since March 2022. IOC and other Indian refiners have significantly increased purchases of Russian oil over the past two years, taking advantage of discounted prices after the West imposed sanctions on Moscow over its full-scale invasion of Ukraine in 2022.
