HS Code for Pneumatic cylinder

Pneumatic cylinders are classified under HS code 8412.31. This code is found within Chapter 84, which covers mechanical appliances and machinery. Heading 8412 is for "Other engines and motors," which includes non-electric power sources like hydraulic and pneumatic engines. Subheading 8412.31 is specifically for pneumatic power engines and motors that are linear acting. These devices, commonly referred to as pneumatic cylinders, convert the potential energy of compressed air into a straight-line mechanical force and motion. The classification is determined by the fluid medium (air) and the type of output (linear). These components are essential in automation and manufacturing for tasks such as pushing, pulling, or lifting. The HS code applies to the cylinder as a power unit; if the cylinder is integrated into a specific machine and imported as part of that machine, the classification of the entire machine would take precedence over the individual component.

Products Included

• Single-acting pneumatic cylinders
• Double-acting pneumatic cylinders
• Telescopic pneumatic cylinders
• Rodless pneumatic cylinders
• Pneumatic rams (linear acting)

Common Misclassification

The most frequent misclassification is with HS code 8412.21, which is for hydraulic linear acting engines (hydraulic cylinders). While they look similar, the distinction lies in the operating fluid (oil vs. air). Another error is using 8412.39, which is for pneumatic motors that are not linear acting, such as rotary pneumatic motors. Additionally, if a cylinder includes a built-in valve or other complex control mechanisms, some may mistakenly look toward heading 8481 (valves), though 8412.31 remains the primary code for the actuator itself.
