2701.19.00.10 - Sub-bituminous coal

This category encompasses sub-bituminous coal, a specific type of coal characterized by its intermediate rank between lignite and bituminous coal. Sub-bituminous coal has a higher heating value and lower moisture content compared to lignite, but a lower carbon content and heating value than bituminous coal. It typically exhibits a dull black appearance and may contain significant amounts of inherent moisture. Its primary use is as a fuel source in power generation and industrial heating.

This classification is distinct from its sibling category, 2701.19.00.50, which is designated for "Other" coal not otherwise specified under the heading 2701.19. The key differentiator lies in the specific technical characteristics defining sub-bituminous coal. While both fall under "Other coal," 2701.19.00.10 is reserved for coal meeting the defined parameters of sub-bituminous coal, leaving 2701.19.00.50 for any remaining coal types that do not fit the sub-bituminous definition or other more specific classifications within Chapter 27.

As this node is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification at this level is determined by the established properties of sub-bituminous coal. Practical classification often relies on laboratory analysis to determine calorific value, moisture content, volatile matter, and fixed carbon to confirm its identity as sub-bituminous coal, distinguishing it from other coal ranks.
