The Iranian foreign minister paid a brief visit to New Delhi on Tuesday to hold talks with Ms Swaraj.
Talking to media at the airport on arrival, Zarif said, India is one of the most important partners of Iran and both countries have regular consultations on various issues. Iran is its third largest supplier after Iraq and Saudi Arabia and meets about 10 per cent of its total needs.
However, the new government that is expected to be in place within the next three weeks in New Delhi is expected to take a final decision on the matter.
External Affairs Minister Sushma Swaraj held "constructive" talks with her Iranian counterpart Javad Zarif on Tuesday and conveyed to him that India will take a decision on import of Iranian oil after the Lok Sabha polls.
Zarif and Swaraj are also likely to discuss the future of the Chabahar port project because the Trump administration has assured that exemption on Chabahar will continue.

President Emmanuel Macron's office said a USA woman and a South Korean woman were also freed in the covert operation. Parly also thanked local authorities and the "precious support of our American allies in conducting this operation".
During the visit, India and Iran signed almost a dozen agreements, centrepiece of which was a deal on development of Chabahar port.
The meeting between the two foreign ministers comes in the wake of heightened diplomatic tension between Iran and the United States after Washington on April 22 announced that no fresh sanction waivers will be issued for Iranian oil imports to eight countries, including India.
In November, the US granted a six-month waiver to India and seven other countries to continue importing oil from Iran. The United States- under then President Barack Obama - had pushed for the deal strongly four years ago.
Indian foreign minister and other parties involved in Iran's nuclear deal placed their special emphasis on backing Joint Comprehensive Plan of Action (JCPOA) wholeheartedly, he said, adding, "we have reiterated that Islamic Republic of Iran has lived up to all its commitments within the framework of JCPOA".
