2N3904 NPN RF Transistor
The 2N3904 is a general-purpose NPN silicon transistor commonly used in RF amplification and switching circuits, with an operating frequency exceeding 100 MHz and dissipation rate under 1W. It falls under HTS 8541.21.00.75 due to its transistor function, low power dissipation, and high-frequency capability for applications like FM radios and wireless devices.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If dissipation rate under 1W but frequency below 100 MHz
Lower frequency transistors fall into the broader low-dissipation category without high-frequency specification.
If imported as part of a complete integrated circuit chip
Processors and controllers in IC form are classified under heading 8542, not discrete transistors.
If assembled into a finished radio transmitter module
When incorporated into communication apparatus, classification shifts to the complete machine.

Import Tips & Compliance
• Verify datasheet confirms dissipation <1W and frequency ≥100 MHz to avoid reclassification
• Include manufacturer specs and test reports in documentation for CBP review
• Beware of mislabeling as general transistors (8541.21.00.00), which have different rates
