8502.39.00 - Other

This HTS category, 8502.39.00, encompasses electric generating sets not specifically classified elsewhere within the broader "Other generating sets" heading, and which are not wind-powered. This includes a diverse range of self-contained units designed to produce electrical energy. The primary distinguishing factor from its sibling, 8502.31.00, is the absence of wind as the primary motive force for generation. Therefore, this category would cover generating sets powered by various other means, such as internal combustion engines, diesel engines, or gas turbines, provided they are not wind-driven.

The purpose of this residual classification is to ensure that all electric generating sets, excluding those specifically enumerated, are accounted for within the tariff system. It serves as a catch-all for a variety of power generation equipment that doesn't fit into more specific subheadings, thereby facilitating accurate customs declarations and duty assessments. The classification relies on the principal source of power driving the generator.

Within this category, further subdivisions exist to provide more granular classification. The subcategory 8502.39.00.40 specifically addresses generating sets powered by a steam turbine, recognizing this as a distinct technological approach to electricity generation. The remaining generating sets that do not utilize steam turbines, and are not wind-powered, are further categorized under 8502.39.00.80, ensuring that all other non-wind-powered generating sets are appropriately classified.
