NTC Thermistor Bead Assembly
A negative temperature coefficient (NTC) thermistor bead with leads for temperature sensing in HVAC systems and battery management. It consists of a glass-encapsulated ceramic bead. This is a part of a resistor, but since it is not made of ceramic or metallic materials that are electrically or mechanically reactive to temperature changes for the specific goods of tariff item 8533.40.00, it falls under 'Other' parts.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the bead is designed to be electrically reactive to temperature changes and is for the goods of that item
This alternative applies when the thermistor bead is specifically for temperature-reactive resistors, which may not be the case for general-purpose NTC beads.
If the bead is presented as a complete fixed resistor rather than a part
Complete fixed resistors are classified under this item, while the candidate is only a component.

The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Ensure the thermistor bead is declared as a part, not a complete thermistor, to avoid misclassification
• Provide technical specifications to CBSA to demonstrate it is not a temperature-reactive part for tariff item 8533.40.00
• Verify if the product is subject to any import restrictions or requires certification
