Coal API (American Petroleum Institute)

Coal API (American Petroleum Institute) refers to standardized measurement codes used to identify different grades and qualities of coal, such as its type, origin, and suitability for specific uses. These codes help producers, traders, and consumers communicate precisely about coal specifications, ensuring consistency and clarity in transactions and processing. While API standards are widely associated with oil and gas, similar coding and classification systems are used across energy sectors, including coal, to facilitate accurate identification and quality assurance in the industry.
