Under GST input tax credit on coal cess is limited to only the tax liability of the cess. However, steel and aluminium manufacturing companies use coal as an input but are not eligible for the compensation cess credit. The unutilised input credit can be claimed as refund, but only if the product (i.e. steel or aluminum) is exported.

The use of coal to produce coke for steel making, as well as other industrial, commercial, and institutional uses, accounts for the remainder of U.S. coal consumption. There are numerous coal beds, of varying thickness, extent, and quality, in coal fields and basins spread throughout the U. S. - these compose the total coal resources of the nation.

Jul 29, 2022Coking coal is used in large-scale industrial processes. The coal is coked, a process of heating the rock in the absense of oxygen. This reduces the moisture content and makes it a m ore stable product. The steel industry relies on coking coal. Bituminous coal accounts for almost half of all the coal that is used for energy in the United States.
