More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If designed as a self-opening diehead
Self-opening dieheads for gear cutting are classified separately from standard work holders.
If for use with numerically controlled gear machines
Parts for NC/CNC machines may fall under specific NC provisions even if for gear cutting.
If considered a gear itself rather than holder
Finished gears or gear blanks are classified in Chapter 84 heading 8483, not as machine parts.
