Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If integrated into complete lift/handling truck assemblies
Complete semiconductor wafer handling trucks classify in heading 8428, carrying parts with them.
If pneumatic tires mounted on the road wheels
Separate pneumatic tires for machinery wheels classify earlier in the parts heading.

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
• Classify as sets if importing complete wheel assemblies with axles; single wheels may qualify differently
• Maintain records showing principal use with wafer slicing saws for Customs valuation purposes
• Test for cleanroom compatibility certifications to support semiconductor-specific classification
