Bituminous coal is the most widely traded coal grade globally, serving as the primary fuel for thermal power generation and as coking coal for steelmaking — two end uses that command distinct quality specifications and price benchmarks. Thermal grades are evaluated on calorific value and sulfur content, while metallurgical grades are assessed on coking properties and ash levels, making specification documentation critical at the point of import. The non-agglomerated designation separates run-of-mine and crushed product from manufactured solid fuels, which are classified separately.
