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 the balls are presented with other bearing parts as a set
Other parts of ball or roller bearings are classified separately when not presented as individual balls.
If the balls do not meet the precision tolerances of heading 84.82
Steel balls not meeting the tolerance criteria of Note 7 to Chapter 84 are classified as other articles of iron or steel.
