Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as part of a complete pneumatic cylinder assembly
Complete linear acting pneumatic cylinders are classified in 8412.31, pulling parts out of the 'other parts' category.
If designed exclusively for a specific valve type rather than general pneumatic motors
Parts of valves may shift to Chapter 84 heading 8481 if primarily for tap or valve function over motor actuation.
If for measuring or controlling pneumatic pressure in testing equipment
Measuring/control devices for fluid power systems often classify under Chapter 90 for precision instruments.
