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 classified as honing/grinding machines for metal working
Chapter 8460 covers general metal grinding/honing; semiconductor specificity keeps it in 8442.
If for soil/rock grinding unrelated to printing/semiconductors
Different material processing moves to machinery for physical/chemical analysis.
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
• Document grinding precision tolerances (e.g
• ±0.1mm diameter) for customs review
• Ensure machine includes flat-grinding capability as per statistical note requirements
• Avoid reclassification by specifying semiconductor boule use, not general metal grinding
