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 sensor is imported as a complete flow meter with a housing, connectors, and display
Complete instruments for measuring or checking flow are classified in Chapter 90, not as semiconductor components.
If the chip integrates a processor or memory that performs functions beyond simple transduction
Electronic integrated circuits with processing capabilities are classified under 8542.

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
• Confirm the chip is a semiconductor-based transducer and not a complete flow meter with a housing and display, which would fall under another heading
• Provide technical documentation showing the sensing principle to support classification
• If the chip includes a microcontroller for signal conditioning, consider whether it is an integrated circuit under 8542
