Petroleum and Coal Products Manufacturing

Establishments in the Petroleum and Coal Products Manufacturing industry primarily engage in transforming crude petroleum and coal into usable products. The core activities include refining crude oil into products such as gasoline, diesel fuel, and asphalt, as well as manufacturing coke and other coal products. This industry is distinguished from closely related industries by its focus on the initial processing and refining of raw petroleum and coal materials, rather than the extraction of crude oil or coal mining.
