Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If advanced beyond basic cleaning with additional machining like precision grinding
Parts advanced beyond cleaning and basic machining for location fall under 'other' machined metal parts, not the specific cast-iron exception.
If not specifically designed for use solely with 8462/8463 machines
General cast iron castings not principally for machine tools of 8456-65 classify in Chapter 73 as other cast iron products.
If sold as part of a complete tool holder assembly with other components
Assembled machinery parts or multi-material tool holders shift to Chapter 84 heading for machinery parts not elsewhere specified.

Import Tips & Compliance
ā¢ Verify the part is solely for machines of 8462/8463 with documentation proving minimal machining beyond cleaning and defect removal
ā¢ Include foundry certificates confirming cast-iron composition and that no advanced finishing like grinding or heat treatment was performed
ā¢ Avoid misclassification as finished parts (8466.94.85); common pitfall is over-machining which shifts to 'other' subheadings
