Ceramic Motor End Cap Insulator
Ceramic motor end cap insulators are insulating fittings designed for electric motors, preventing electrical contact between rotor and stator windings. They feature molded-in metal sockets for bolt assembly while preserving full insulation properties. These fittings fall under tariff item 8547.10.00 as ceramic insulating fittings for electrical machinery.

More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the end cap is presented as an identifiable part of an electric motor
Parts suitable for use solely or principally with electric motors of heading 8501 may fall under heading 8503.
If the end cap functions as an electrical insulator rather than a fitting
Heading 8546 covers other electrical insulators of any material, which are excluded from heading 8547.

Import Tips & Compliance
• Confirm that the metal sockets are minor components added only for assembly purposes; if they serve another function, classification may change
• Keep records of the ceramic material composition and manufacturing process for CBSA verification
• Check if the motor end cap qualifies as a part of an electric motor under heading 8503 for potential alternative classification
