Hence, statement 1 is not correct. India does not have enough reserves for good quality coking coal and most of it is imported from Indonesia, South Africa, Russia, and Australia. Hence, statement 2 is correct.
Coking coal is imported by the state-run Steel Authority of India Limited (SAIL) and other steel manufacturing units mainly to bridge the gap between the requirement and indigenous availability and to improve the quality. Hence, statement 3 is correct.
