Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If designed for cylindrical roller spindles
Different roller geometry moves it to general other rings/races, not tapered-specific.
If imported as part of a complete machine tool
Integrated into finished tools, classification follows the machine under heading 8466.
If for low-speed industrial flywheels
Plain bearing races (non-rolling element) fall into separate pulley/gear provisions.

Our AI classifier can analyze your specific product and recommend the correct HTS code with confidence.
Import Tips & Compliance
• Include spindle RPM ratings and tolerance certificates (e.g
• ABEC/ISO P4) for accurate duty assessment
• Declare as 'machinery parts' only if end-use proven; standalone parts stay in Chapter 84
