8517 - Telephone sets, including smartphones and other telephones for cellular networks or for other wireless networks; other apparatus for the transmission or reception of voice, images or other data, including apparatus for communication in a wired or wireless network (such as a local or wide area network), other than transmission or reception apparatus of heading 8443, 8525, 8527 or 8528; parts thereof:

Heading 8517 encompasses a broad range of telecommunication equipment. This includes fundamental telephone sets, notably smartphones and other devices designed for cellular or wireless networks. It also covers a variety of other apparatus essential for transmitting and receiving voice, images, or data. Crucially, this heading captures devices used for wired or wireless network communication, such as those found in local area networks (LANs) or wide area networks (WANs).

The scope of 8517 is distinct from other headings within Chapter 85 that might also deal with transmission or reception. For instance, it excludes apparatus classified under headings 8443 (printers), 8525 (transmitters and apparatus for radio-telephony or radio-telegraphy), 8527 (reception apparatus for radio-telephony or radio-telegraphy), and 8528 (monitors and projectors). The primary distinguishing factor is the specific function related to general communication networks, as opposed to specialized transmission or display equipment.

Further subdivisions within 8517 clarify its extensive coverage. The subcategories delineate between the end-user telephone sets and the broader category of network communication apparatus. Additionally, a specific provision for "Parts" ensures that components and accessories integral to the functioning of these telecommunication devices are appropriately classified under this heading, facilitating a comprehensive import/export process.
