N363511 · 2026-08-17 — RE: The tariff classification of a linear acting hydraulic cylinder from China
Product information was submitted with your request. The item under consideration is a linear acting hydraulic cylinder (Part Number 499241-101) which will be used to control ailerons on the wing of a commercial aircraft. Specifically, it converts fluid pressure into linear force to extend or retract its piston rod. This bidirectional motion of the piston rod controls the action of the aileron. As described, the cylinder utilizes integrated lugs which mount directly to the hydraulic manifold block. In addition, it features a specialized rod-end configured to link to the structural load path…
N355148 · 2025-11-06 — The tariff classification and country of origin of clutch slave cylinders
The item under consideration has been identified as a motorcycle clutch slave cylinder, specifically models CLU-0116, CLU-0120, CLU-0121, CLU-1125, and CLU-4000. You state that all models are the same product, just for different models of motorcycle. The finished unit bolts to the side of the motorcycle engine (on those that rely on a hydraulic actuator to operate the separation of the clutch plates) and transmits hydraulic pressure from the master cylinder, at the clutch lever, to the clutch pushrod. You state that these parts are supplied as replacement parts to original manufacturers, as…
N091357 · 2010-02-01 — The tariff classification of a treadle valve, hydraulic cylinder and pneumatic cylinder from China
Descriptive literature and illustrations were submitted. The items under consideration are described as a treadle valve, part number 132923 WM-472-200, an hydraulic throttle control cylinder, part number 119436 WM-512-C, and a pneumatic throttle control cylinder, part number 117985 WM-388-105. The WM-472 series treadle valve is a three-way, compensating pressure regulator commonly used in pneumatic braking systems. Each unit is comprised of a valve subassembly that responds to movement of the pedal and modulates the flow of air within the braking system. When the operator pushes down on the…
N028750 · 2008-06-16 — The tariff classification of hydraulic cylinders from China
The articles in question are described as hydraulic cylinders used on travel trailers to power “slide outs”, which are used to create more interior space when the trailer is parked. Our review of the technical drawings you have submitted reveal that the cylinders are linear hydraulic motors. The applicable subheading for the hydraulic cylinders will be 8412.21.0075, Harmonized Tariff Schedule of the United States (HTSUS), which provides for other linear acting hydraulic power engines and motors. The rate of duty is free. Duty rates are provided for your convenience and are subject to change.…
N006160 · 2007-03-01 — The tariff classification of master and slave cylinders from Mexico
The articles in question are described as master cylinders, slave cylinders and concentric slave cylinders for use in automotive hydraulic systems. The master cylinders are pedal actuated piston pumps that convert mechanical force into fluid power by pressurizing hydraulic fluid within a hydraulic system. The slave cylinders are linear actuators that convert pressurized fluid within the hydraulic system into mechanical energy. Descriptive information and photographs were submitted. In your request you aver that the master cylinders are properly classified in heading 8413, Harmonized Tariff…
