Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as raw material, not assembled into transformer core
Loose grain-oriented silicon-electrical steel sheets classified by material composition in Chapter 72, not as transformer parts
If considered a complete static converter rather than just a part
Finished power supplies or converters go under specific static converter subheadings, not parts
If designed specifically for use in electric motors
Parts of motors/generators classified under heading 8503 when end-use is motor-specific
