Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not numerically controlled
Non-NC honing/lapping machines fall under the general 'other' category with different duty rates.
If specialized for semiconductor wafer lapping
Statistical notes direct wafer lappers in semiconductor processing to machines and apparatus provisions.
If new rather than used/rebuilt
New NC honing/lapping machines are classified separately from used equipment.

Import Tips & Compliance
• Provide detailed service records and certification proving 'used or rebuilt' status to qualify for this subheading
• Confirm numerical control features and metal/ceramic finishing capability; misclassification as new risks higher duties
• Include end-user declarations if for semiconductor fab to avoid anti-dumping scrutiny on precision tools
