Overview
This classification covers hubs specifically designed for use in wind turbines. The hub is the central component of a wind turbine rotor, to which the blades are attached. It serves as the critical interface that connects the rotating blades to the main shaft, transmitting the rotational forces generated by wind energy. Examples include hubs manufactured from various materials, such as steel, aluminum, or composites, intended for direct integration into wind turbine systems for the purpose of generating electricity.
This category is distinguished from its sibling, 8412.90.90.70, which specifically classifies wind turbine blades. While blades are the primary energy capture components, this classification focuses solely on the central hub that supports and connects these blades. It also differs from the sibling category 8412.90.90.85, which is a residual category for all other unspecified parts of engines and motors not elsewhere enumerated.
As a leaf node within the HTS classification system, 8412.90.90.75 does not have further subcategories. Therefore, the classification of wind turbine hubs is finalized at this level. When classifying such parts, consideration should be given to their definitive role as a wind turbine component and their physical characteristics that enable attachment to both the blades and the turbine's drive train.
