Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the cylinder is a welded fabrication rather than a casting
The specific item covers castings; other forms of cylinders fall under the residual heading.
If the cylinder is a standard hydraulic actuator not dedicated to rubber molding machines
Hydraulic power engines are classified in heading 84.12 when not machine-specific parts.
