Used Okamoto ACC-322DXNC Lapping Machine
A numerically controlled lapping machine designed for finishing flat metal surfaces to high precision tolerances using abrasive slurries. Classified under HTS 8460.40.40.10 as a used machine for lapping metal surfaces, distinct from gear finishing equipment in heading 8461.
Import Duty Rates by Country of Origin
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.
Not sure which classification is right?
The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
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
