Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified primarily as a bearing part rather than gearbox component
Other parts of ball/roller bearings fall under Chapter 84 heading 8482.
If used in hydroelectric turbine gearboxes
Only wind turbine-specific gearbox parts get the 8483.90.5020 designation.
If imported as simple fabricated steel ring without precision machining
Basic steel articles not having specific transmission function classified by material.

Import Tips & Compliance
• Include bearing manufacturer specs showing compatibility with wind turbine gearbox designs (e.g
• SKF or FAG)
• Document surface hardness (HRC 58-62) and material (e.g
• 18NiCrMo5) required for wind applications
• Avoid common pitfall of classifying as general bearing housing (8483.20) by proving gearbox-specific function
