The Persian Gulf nation is now insisting on being paid in Euros for the oil it sells to Indian refiners. It also wants refiners like Essar Oil and Mangalore Refinery and Petrochemicals Ltd (MPRL) to clear nearly USD 6.5 billion of past dues in Euros, officials said.
Iran had in November 2013 offered free delivery of crude oil to Indian refiners as tough Western sanctions crippled its exports.
With shipping lines refusing to transport Iranian crude for fear of being sanctioned, Iran used its shipping line for the delivery and did not charge for transportation. "National Iranian Oil Company (NIOC) has written to Indian firms saying it will no longer be shipping oil for free," an official said.
"It will continue to ship the oil in its tankers but will charge a discounted tariff," he said. The transportation fee will for now be less than half it takes to ferry oil from Iran. "May be in future this 50 per cent discount too may go," he added.
Iran however has continued with its liberal fiscal terms of offering 90-day credit period - i.e payment becomes due only after three months of invoice being raised.
With US lifting sanctions in January, Iran has told Indian authorities that the three-year old mechanism of paying 45 per cent of oil import bill in rupees and keeping the remaining 55 per cent pending for payment channels to clear, stands terminated.
The pending payments now total to nearly USD 6.5 billion which Iran has agreed to receive in instalments over the next six months, officials said.
"NIOC is raising invoice for oil it is now exporting to Indian refiners in Euros," he said. Since February 2013, Indian refiners like Essar Oil and MRPL paid 45 per cent of their import bill in rupees to UCO Bank account of Iranian oil company.
The remaining has been accumulating, pending finalisation of a payment mechanism. With the lifting of sanctions, the payment channels will reopen and Iran is seeking the pending USD 6.6 billion in Euros.
The payments would be done in instalments to prevent a run on the rupee with MRPL likely to be asked to clear its outstanding dues of close to USD 3 billion first. Indian Oil Corp (IOC), which owes over USD 580 million to Iran, may be the second in the queue followed by smaller payments by HPCL-Mittal Energy Ltd (HMEL) and Hindustan Petroleum Corp.
Essar Oil may be the last to clear its about USD 3 billion dues. Officials said Iran has not yet decided on utilisation of the USD 3 billion which has accumulated in the rupee account with UCO Bank. It could use the money to make payments for imports of steel and other commodities from India.
