Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If hydraulic rather than pneumatic
Hydraulic brakes and parts fall under separate subheading for non-air brake systems.
If imported as standalone pneumatic cylinder without rail-specific mounting
General pneumatic cylinders are classified by function in Chapter 84, not rail-specific parts.
If for engine air supply systems, not direct brake actuation
Linear acting hydraulic/pneumatic cylinders for engines go to heading 8412.
