Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as part of complete paper pulp machinery
Integral parts of pulp/paper machines are covered in 8439, separate transmission components in 8483.
If for clutch mechanisms rather than pure speed changing
If primary function is clutching rather than speed ratio change, shifts to clutches and couplings heading.
If power-operated automatic ratio selection
Manual manipulation required for this subheading; automatic goes to other speed changer provisions.
