Despite US sanctions, India has not asked its refiners to reduce crude  oil imports from Iran, according to the Ministry of Petroleum and  Natural Gas. 
 India is, however, looking for alternative supplies. Iran meets 12 per  cent of India's needs. MRPL is the largest importer of Iranian crude oil  at about 150,000 barrels a day. 
 Washington imposed additional sanctions on Iran last month, and the  European Union will have a meeting on January 23 to decide on whether to  embargo Iran's oil. Iran has threatened to retaliate against the West  by closing the Strait of Hormuz. 
 The US now also has a law allowing penalties on foreign banks that settle oil import bills with Iran's central bank. 
 The law provides waivers to firms in countries that significantly reduce  crude oil supplies from Iran. India may seek that waiver or consider  going in for a barter system. 
 A delegation will visit Tehran from January 16 to explore alternative  routes of payment. Brent crude rose more than $1 a barrel on January 13 on  worries that a showdown between Iran and the West and a strike in  Nigeria could disrupt oil supplies, reports Reuters.
