8412.90.90.70 - Wind turbine blades, imported in accordance with statistical note 2 of this chapter

This HTS classification, 8412.90.90.70, specifically designates wind turbine blades that are imported under the conditions outlined in statistical note 2 of Chapter 84. These blades are crucial components of wind turbines, designed to capture kinetic energy from the wind and convert it into rotational mechanical energy. Their construction and design are optimized for aerodynamics and structural integrity to withstand the forces encountered during wind turbine operation.

Distinguishing this category from its siblings, 8412.90.90.75 covers wind turbine hubs, which are the central component to which the blades are attached. The distinction lies in the functional role and physical form; blades are the rotating airfoils, while hubs are the stationary or rotating connectors. The sibling category 8412.90.90.85 serves as a residual category for any other parts of engines and motors not elsewhere specified within this subheading.

As this is a leaf node, there are no further subcategories. Therefore, the classification of wind turbine blades under this code hinges on their identity as such and adherence to the specified statistical note requirements. Importers should ensure documentation confirms compliance with these provisions to ensure correct classification.
