U.S. imports of reciprocating positive displacement pumps, nesoi (HS 841350) totaled $177.7M in July 2026, traded with 84 countries.
Importers of Reciprocating Positive Displacement Pumps, NESOI paid $12.1M in duties in July 2026 — an effective duty rate of 12% on $97.0M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataReciprocating positive displacement pumps outside more specific headings span a wide performance range: from oilfield plunger pumps (8413500010) and diaphragm pumps for chemical transfer (8413500050) to radial-piston hydraulic power units (8413500070) and other hydraulic fluid power pumps (8413500080). Mexico and Japan lead US imports, with Germany a close third — a sourcing mix that reflects both high-volume OEM automotive hydraulic components and precision industrial pump manufacturing. Diaphragm pumps used in chemical or pharmaceutical processes may be subject to end-use regulations beyond CBP's scope, depending on the media being transferred.

The radial-piston line specifically covers hydraulic pumps where pistons are arranged radially around a central drive shaft, a design used in high-pressure, low-speed applications. All other reciprocating hydraulic fluid power pumps — including axial-piston designs — fall under the NESOI hydraulic line (8413500080). The piston geometry and arrangement are the key technical differentiators for classification.
The oilfield pump line carries its own 10-digit statistical breakout, which allows CBP and industry to track trade flows separately, but duty treatment is determined at the HTS heading level and any applicable trade remedy orders. Importers should verify whether any Section 301 or antidumping measures apply to the specific country of origin, as oilfield equipment sourcing from China has been subject to additional tariffs.
