U.S. imports of pressure-reducing valves (HS 848110) totaled $46.3M in July 2026, traded with 60 countries.
Importers of Pressure-Reducing Valves paid $4.1M in duties in July 2026 — an effective duty rate of 14% on $29.3M in dutiable value, based on actual customs collections rather than the published tariff schedule. Pressure-Reducing Valves imports of $46.3M in July 2026 ran 14% above the year-to-date monthly average of $40.6M.
Last updated: July 2026 dataPressure-reducing valves regulate downstream line pressure in hydraulic and pneumatic fluid power systems, making them critical safety and performance components in industrial machinery, oil and gas infrastructure, and HVAC applications. The US schedule subdivides this heading by fluid medium and function: hydraulic fluid power types (8481100020), pneumatic control valves (8481100040), pneumatic fluid power valves (8481100060), and a residual NESOI line (8481100090). Mexico is the leading supplier of US imports under this heading, reflecting deep cross-border integration in fluid power manufacturing, with Italy and China also significant sources. Chinese-origin goods in this heading may be subject to Section 301 tariffs.

Under the US schedule, pneumatic pressure-reducing control valves (8481100040) are distinguished from general pneumatic fluid power pressure-reducing valves (8481100060) by their control function — the control valve modulates output pressure in response to a signal or set point, while the standard type provides passive pressure reduction. The technical specification sheet and the valve's operating mechanism are the key classification evidence.
For most industrial pressure-reducing valves, standard CBP entry documentation applies. However, valves destined for use in pressure vessels or pipelines subject to ASME or DOT standards may require conformity documentation for the end-use application. Valves with dual-use potential may also warrant an export control review on the foreign side. Consult a licensed customs broker to confirm documentation requirements for your specific product and end use.
