"As far as quantity of import from Iran is considered, there are alternatives. Also, comparable grade of oil is also available. However, there were discounts given by Iran (which others may not offer)," said MK Surana, chairman and managing director, Hindustan Petroleum Corporation (HPCL). Tehran provides Indian importers a credit of 90 days compared with around 30 days by other suppliers. Iran is the third-largest supplier for the country after Iraq and Saudi Arabia. Analysts feel that India could even keep the current level of purchases from Iran despite the US move. "While nations such as China, India and Turkey may oppose the US move and keep current levels of Iranian crude purchases, American allies including Japan and South Korea may comply because of concerns they could lose a security umbrella against North Korea," Bloomberg quoted MUFG Bank as saying. According to Dilip Khanna, partner with EY, though there could be a negative impact on India, the fine print of the sanctions have to be seen.
