Anthracite: It is the highest quality hard coal. It is found in parts of Jammu and Kashmir.

Bituminous: This coal has been buried deep and subjected to increased temperatures. It is the most popular coal in commercial use. Metallurgical coal is high grade bituminous coal which has a special value for smelting iron in blast furnaces.

Lignite: It is a low grade brown coal, which is soft with high moisture content. The lignite reserves are in Neyveli in Tamil Nadu. It is used for the generation of electricity.

Peat: Decaying plants in swamps produce peat, which has low carbon content and high moisture content resulting in low heating capacity.
