The government has taken several steps to secure coking coal supplies for the domestic steel industry and is making efforts to diversify the raw material's import sources. While output of iron ore, another key raw material for the steel industry, in the country is sufficient to meet the current demand, the entire demand of coking coal is not met from domestic production as the availability of high-quality coking coal (low-ash coal) in the country is limited and, thus, no option is left but to resort to import of coking coal, Union Steel Minister Dharmendra Pradhan said in a reply to a query in the Lok Sabha as reported by PTI.
