Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If other semiconductor wafer finishing equipment
Specific wafer polishers for semiconductor manufacture classify under statistical semiconductor provisions.
If general precision polishing without semiconductor function
Non-specialized polishers fall under Chapter 84 machine tools.
If for laboratory glassware polishing
Lab-scale glass polishers classify as glassware, not industrial assembly machines.

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
• Technical specs must demonstrate semiconductor surface prep for glass sealing processes
• Cross-reference chapter statistical notes excluding Chapter 90 testing polishers
