HS Code for Air cylinder

Air cylinders, also known as pneumatic cylinders, are classified under HS code 8412.31. This code is situated within Chapter 84 and specifically falls under heading 8412, which covers other engines and motors. Subheading 8412.31 is dedicated to pneumatic power engines and motors that are linear acting. The classification is based on the device's function as a power source that converts the energy of compressed air into a reciprocating linear motion. These components are essential in automation, robotics, and manufacturing processes. The "linear acting" designation distinguishes these cylinders from rotary pneumatic motors. Under the Harmonized System, the classification is driven by the mechanical nature of the device and its reliance on pneumatic pressure to perform work, rather than the machinery it is eventually installed into.

Products Included

• Double-acting pneumatic cylinders
• Single-acting spring-return cylinders
• Rodless air cylinders
• Tandem pneumatic cylinders
• Pneumatic actuators with linear motion

Common Misclassification

Air cylinders are often misclassified under HS code 8412.21, which is for hydraulic linear acting engines. The difference lies entirely in the fluid medium; 8412.31 is for air (pneumatic), while 8412.21 is for liquid (hydraulic). Another error is classifying them under 8481.20 as valves for pneumatic transmission. While cylinders and valves work together, the cylinder is the motor/engine (8412) and the valve is the control mechanism (8481).

FAQ

What is the HS code for air cylinder?

The HS code for linear acting pneumatic air cylinders is 8412.31.

Are the mounting brackets for air cylinders included in this code?

Parts for these engines, including specialized brackets, are typically classified under HS code 8412.90, provided they are suitable for use solely or principally with the engines of heading 8412.
