U.S. exports of hydraulic & pneumatic automatic regulating or controlling instruments (HS 903281) totaled $13.2M in July 2026.
Importers of Hydraulic & Pneumatic Automatic Regulating or Controlling Instruments paid $879K in duties in July 2026 — an effective duty rate of 11% on $8.3M in dutiable value, based on actual customs collections rather than the published tariff schedule. Hydraulic & Pneumatic Automatic Regulating or Controlling Instruments imports of $10.9M in July 2026 ran 51% above the year-to-date monthly average of $7.2M.
Last updated: July 2026 dataFluid-power control is the defining characteristic here: instruments and apparatus that use hydraulic or pneumatic action — rather than electrical signals alone — to automatically regulate process variables such as pressure, flow, or position. The four 10-digit lines separate hydraulic industrial process control (9032810020), combined hydraulic/pneumatic industrial process control (9032810040), pneumatic industrial process control (9032810060), and non-industrial hydraulic/pneumatic instruments (9032810080). Germany leads US supply, consistent with its strength in industrial automation and fluid-power engineering, with Canada and Mexico also prominent. USMCA preferential treatment may be available for qualifying goods from Canada and Mexico.

The US schedule distinguishes instruments used in industrial process control environments — such as chemical plants, refineries, or manufacturing lines — from hydraulic or pneumatic instruments used in other applications (e.g., mobile equipment, HVAC, or laboratory settings). The non-industrial line 9032810080 captures the latter. Importers should document the intended end-use application and the instrument's design specifications, as CBP may request evidence that a device is purpose-built for industrial process control versus general-purpose fluid-power regulation.
Useful documentation includes the manufacturer's product datasheet specifying the instrument's rated operating environment (e.g., ATEX or NEC hazardous-location certification, process-industry pressure and temperature ratings), the commercial invoice description referencing the industrial application, and any end-use certificates from the buyer. CBP may also consider whether the instrument is designed to interface with distributed control systems (DCS) or programmable logic controllers (PLCs) standard in industrial process environments.
