India had earlier threatened to order state refiners, namely Hindustan Petroleum, Bharat Petroleum, Mangalore Refinery and Petrochemicals Ltd, and Indian Oil Corp to cut oil procurement from Iran.
The developments follow a row between New Delhi and Tehran over an Iranian gas field.
India plans to cut Iranian oil imports
India imported 510,000 bpd of oil from Iran last year
India is the second largest importer of Iranian crude oil. Last year, India imported around 510,000 barrels per day (bpd) of crude from Iran, according to Thomson Reuters Eikon shipping data. Following India's planned oil cut, this could reduce to 370,000 bpd this year.
Why are India and Iran sparring over natural gas field
In 2008, an ONGC-led consortium of Indian companies had discovered the Farzad B natural gas field in Iran, which holds an estimated 12.5 trillion cubic feet of reserves.
Due to international sanctions on Iran, the India consortium was unable to develop the oil field.
Iran has refused to grant developmental rights to India despite sanctions being lifted following the 2015 Iran nuclear deal.
