SITCSection 7
U.S. imports of reciprocating positive displacement pumps, n.e.s. (SITC 74240) totaled $201.2M in April 2026, traded with 75 countries.
Importers of Reciprocating Positive Displacement Pumps, N.E.S. paid $14.9M in duties in April 2026 — an effective duty rate of 13% on $111.9M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataReciprocating positive displacement pumps move fluid by the back-and-forth motion of a piston, plunger, or diaphragm, making them the preferred choice for high-pressure, low-flow applications in oil and gas, chemical processing, and water treatment. The N.E.S. designation excludes pumps already captured by more specific headings — such as engine fuel pumps or metered dispensing pumps — leaving a broad range of industrial piston and diaphragm pumps in this category. Importers should note that high-pressure reciprocating pumps used in hydraulic fracturing or pipeline injection may face additional scrutiny under energy-sector trade-remedy orders.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Diaphragm pumps operate by the reciprocating flexion of a membrane rather than a piston or plunger, but they are still classified as reciprocating positive displacement pumps because the displacement mechanism moves back and forth to trap and expel fluid. Air-operated double-diaphragm (AODD) pumps are a common trade item in this heading.
Importers should retain technical data sheets confirming the pump's operating principle (reciprocating motion), flow and pressure specifications, and intended application, along with a written classification analysis ruling out more specific headings. For recurring high-volume imports, a CBP binding ruling provides the strongest protection against reclassification.
