Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If incorporating electrical conductors
Insulating fittings with integrated terminals or conductors are classified as insulating fittings of base metal rather than pure insulators.
If for industrial furnace or kiln applications
Ceramic insulators designed for high-temperature furnace use rather than electrical insulation fall under laboratory or kiln ceramic ware.
Not sure which classification is right?
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
• Certify compliance with UL 94 flammability standards; specify thread size and mounting hole dimensions; ensure marking of voltage and temperature ratings
