8542.39.00.10 - RF transceivers

This HTS subheading, 8542.39.00.10, specifically classifies radio frequency (RF) transceivers. These are electronic integrated circuits designed to transmit and receive radio waves, commonly found in wireless communication devices such as mobile phones, Wi-Fi modules, Bluetooth devices, and various types of wireless networking equipment. The core function of these circuits is to manage the modulation and demodulation of signals for wireless data transfer.

Distinguishing this category from its siblings, 8542.39.00.20 covers active filters, which are designed to modify signal frequencies, while 8542.39.00.70 and 8542.39.00.90 encompass broader categories of "other" integrated circuits with adjustable performance characteristics or those not elsewhere specified. RF transceivers are distinct in their dual transmit and receive functionality, operating within specific radio frequency bands for wireless communication protocols.

As this is a leaf node within the HTS classification system, there are no further subcategories. Therefore, classification under 8542.39.00.10 hinges on the primary function and design of the integrated circuit being for radio frequency transmission and reception. Importers and exporters should ensure that the primary purpose of the integrated circuit is for RF communication, rather than signal filtering or general data conversion, to correctly apply this subheading.
