Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as 'matched set' with multiple bearings
Matched bearing sets for precise alignment have separate statistical reporting.
If when imported specifically as replacement part for wafer grinder machines
Parts solely for semiconductor wafer prep machines may fall under machines and mechanical appliances heading.
If designed as needle roller bearing variant
Different roller element type changes from ball to roller bearing classification.

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 dimensional tolerance certificates (e.g
• ISO 286) critical for boule grinding precision
• Label with 'semiconductor grade' to distinguish from general industrial bearings during customs review
• Avoid common pitfall of missing RoHS compliance docs for electronics manufacturing imports
