The rise in the purchase of the Iranian crude comes despite Washington's appeals for a reduction of oil imports from Iran by around 15 percent in volume.
The White House is now concerned that it may have to impose sanctions on New Delhi for its refusal to cut back on crude purchases from Tehran.
Earlier on Tuesday, Turkey's Minister of Energy and Natural Resources Taner Yildiz announced that Turkey is continuing to purchase crude oil from the Islamic Republic.
Oil prices have remained high following Iran's decision to cut oil sales to some European countries in response to the EU's sanctions on the country.
On January 23, EU foreign ministers approved sanctions against Iran, including a ban on Iranian oil imports, a freeze on the assets of the Central Bank of Iran within the blocβs states and a ban on selling diamonds, gold, and other precious metals to Tehran.
The US, Israel and some of their allies accuse Tehran of pursuing military objectives in its nuclear energy program.
Iran has repeatedly refuted the Western allegations regarding its nuclear energy program, arguing that as a signatory to the nuclear Non-Proliferation Treaty and a member of the International Atomic Energy Agency, it is entitled to develop and acquire nuclear technology for peaceful purposes.
