8412.29.80.30 - Radial piston type

This classification, HTS Code 8412.29.80.30, specifically covers hydraulic power engines and motors of the radial piston type. These engines and motors are characterized by their design where pistons are arranged radially around a central shaft. When hydraulic fluid is introduced, the pistons either reciprocate linearly or pivot, driving the central shaft and producing rotational motion. This category is distinct from other types of hydraulic motors due to the specific radial arrangement of its operating components.

It is crucial to differentiate this category from its siblings. HTS Code 8412.29.80.15 pertains to gear-type hydraulic motors, which utilize meshing gears to generate torque. HTS Code 8412.29.80.45 covers axial piston motors, where pistons are parallel to the output shaft, operating in a swashplate or bent-axis design. Finally, HTS Code 8412.29.80.60 encompasses all other hydraulic motors not falling under the radial piston, gear, or axial piston types, making this "Radial piston type" category quite specific in its scope.

As a leaf node within the HTS structure, this classification does not have further subcategories. Therefore, the defining characteristic for classification under 8412.29.80.30 is the presence of a radial piston design. When determining classification, customs professionals should focus on the physical configuration of the hydraulic motor, specifically identifying whether the pistons are arranged in a radial pattern relative to the output shaft, as opposed to a gear-driven or axial piston mechanism.
