Australia accounts for over half of India's coking coal imports of around 70 million metric tons a year. The steel ministry and the Australian High Commission did not immediately reply to e-mails seeking comment.

As erratic weather conditions hit coking coal supplies from Australia, Indian steel mills have been trying to turn to other countries such as Russia to take advantage of cheaper prices. Still, major Indian producers rely on Australia, especially for some specific grades of the commodity. Some domestic producers such as the government-backed Steel Authority of India (SAIL) want to increase coking coal purchases from Russia due to cheaper prices, SAIL Chairman Amarendu Prakash said last week. Other than Australia and Russia, India also imports coking coal from the U. S.

Last month, prices for Australian coking coal jumped 50% to over $350 a metric ton due to factors such as maintenance outages, lower than usual supplies from Queensland, and a slower train network. Indian mills were looking to raise prices of various grades of steel due to rising coking coal costs, officials told Reuters last month.
