U.S. imports of fluid power pumps & motors (NAICS 333996) totaled $424.8M in July 2026, traded with 97 countries.
Importers of Fluid Power Pumps & Motors paid $42.9M in duties in July 2026 — an effective duty rate of 17% on $246.7M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataHydraulic pumps and motors — gear, vane, piston, and radial designs — are core motion-control components in mobile machinery, industrial presses, marine systems, and renewable-energy equipment. NAICS 333996 also captures pneumatic motors, which are classified separately from their hydraulic counterparts under HTS chapter 84. Displacement volume, maximum operating pressure, and output configuration are the specification parameters that most directly determine tariff subheading, and Chinese-origin units in this category may carry Section 301 tariff exposure that significantly affects landed cost.

Customs classification of hydraulic pumps under chapter 84 turns primarily on the pump's operating principle (gear, vane, or piston), whether it is fixed or variable displacement, and its rated operating pressure. Importers should have the manufacturer's technical datasheet available at entry to support the declared subheading.
Possibly. CBP applies the GRI 'complete or finished article' rules and may classify a matched pump-motor set as a hydrostatic transmission if it is presented as a functional unit with a common housing or mounting. A binding ruling is advisable for high-value integrated units to avoid component-level reclassification.
