2701.19.00 - Other coal

This HTS category, "Other coal," encompasses coal that does not fit into the more specific classifications of anthracite or bituminous coal. It serves as a residual category for coal characterized by its physical properties, such as lower fixed carbon content and higher volatile matter compared to anthracite, and often a lower energy content than bituminous coal. The primary function of these coals remains as a solid fuel for energy generation, industrial processes, and historical heating applications.

Distinction from sibling categories is crucial. Anthracite (2701.11.00.00) is recognized by its high fixed carbon content (typically above 86% by dry, ash-free basis), low volatile matter, and its hard, lustrous appearance. Bituminous coal (2701.12.00), on the other hand, is characterized by a higher heating value, a wider range of fixed carbon content (typically 45% to 86%), and is often black and less lustrous than anthracite. "Other coal" thus includes coals that fall outside these defined parameters, primarily sub-bituminous coal and lignite, which are still in a solid form and derived from coal.

The subcategories within "Other coal" further refine this classification. "Sub-bituminous coal" (2701.19.00.10) represents a distinct type of coal with a fixed carbon content typically between 35% and 45% and a higher volatile matter content than bituminous coal. The residual "Other" subcategory (2701.19.00.50) may include further specific types or lower grades of coal, such as lignite, which are still classified under the broad definition of coal but do not meet the specific criteria for the preceding subdivisions.
