Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If standalone hydraulic cylinder
Hydraulic cylinders for general fluid power use are in Chapter 84.
If for non-semiconductor rubber molders
Parts of unspecified molding machines use the catch-all subheading.
If with integrated pressure sensors
Measuring appliances parts shift to Chapter 90 if testing functionality added.
