8518.30.10.00 - Line telephone handsets

This HTS classification, 8518.30.10.00, specifically designates "Line telephone handsets." These are the devices typically held to the ear and mouth, directly connected via a wire or cable to a telephone system for the transmission and reception of voice. The primary function of these items is to facilitate voice communication within a wired telephone network.

Within the broader heading of 8518.30, which covers headphones, earphones, and microphone sets, this sub-heading carves out a distinct category for telephone handsets. Its sibling, 8518.30.20.00 ("Other"), would encompass other types of headphones and earphones not specifically designed or primarily intended for use as a line telephone handset, such as those used for audio listening or mobile phone communication where the primary input/output is not a dedicated line telephone connection.

As a leaf node within the HTS, 8518.30.10.00 does not have further subcategories. Therefore, classification within this code hinges on whether the item functions as a dedicated line telephone handset. Examples include traditional corded telephone receivers and those for integrated communication systems where the handset is the primary interface for voice communication over a wired circuit.
