Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If fully machined with internal gear teeth
Complete gear rings with teeth are speed changers/gears, not mere parts.
If designed as replaceable part for gear hobbing machines
Parts of gear-cutting machinery classify under metalworking machine tools.
If for testing apparatus in semiconductor device processing
Some transmission testing components for semiconductor devices shift to Chapter 90.
