U.S. imports of pneumatic power engines & motors (non-linear acting) (HS 841239) totaled $21.2M in April 2026, traded with 42 countries.
Importers of Pneumatic Power Engines & Motors (Non-Linear Acting) paid $1.5M in duties in April 2026 — an effective duty rate of 13% on $11.1M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataRotary and oscillating pneumatic motors — devices that convert compressed-air energy into mechanical motion without using a linear cylinder stroke — are classified here, with the US schedule splitting them into unlimited rotary acting (8412390040) and all other non-linear pneumatic motors (8412390080). These units are widely used in industrial automation, mining equipment, and intrinsically safe environments where electric motors pose ignition risks. Poland and Italy are the leading suppliers to the US market, with China, Japan, and Malaysia also contributing meaningfully. Importers should verify whether goods originating from China are subject to Section 301 tariffs, which apply to many industrial machinery subheadings.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The rotary acting line covers motors with unlimited or continuous rotary output — think vane, gear, or piston air motors that spin a shaft. The NESOI line captures non-linear pneumatic motors that do not fit the rotary description, such as oscillating or semi-rotary actuators. When in doubt, the motor's range of rotation and mechanical output type are the key classification criteria; consult a licensed customs broker for borderline cases.
Many pneumatic motor subheadings under HTS Chapter 84 are subject to Section 301 tariffs on goods of Chinese origin. The applicable list and rate should be confirmed against current USTR guidance, as coverage and exclusions change periodically.
