8406.82.10 - Steam turbines

This HTS category, 8406.82.10, specifically classifies steam turbines and other vapor turbines with an output not exceeding 40 MW. These machines are designed to convert thermal energy from steam or other vapor into mechanical energy, typically used for power generation or industrial processes. The defining characteristic for inclusion here is the power output limit of 40 megawatts, a crucial factor in distinguishing these turbines from larger industrial units.

Within the broader category of "Other turbines," this classification is distinct from its sibling, 8406.82.90.00, which covers all other turbines not meeting the specific criteria of 8406.82.10. Therefore, if a turbine's output exceeds 40 MW, it would fall under the "Other" sibling classification. The key differentiator is the power rating, ensuring accurate and granular classification based on the turbine's capacity.

Further subdivisions exist under this category to refine classification based on design and operational characteristics. These subcategories, such as "Stationary steam turbines, condensing type" and "Other," allow for more precise identification of specific types of turbines. Understanding these subdivisions is essential for accurate reporting and duty assessment, as different turbine designs may have specific implications for trade and regulatory purposes.
