8526.91.00 - Radio navigational aid apparatus

This HTS category, 8526.91.00, specifically encompasses radio navigational aid apparatus. These are devices designed to provide users with information to determine their position, course, or distance, utilizing radio waves for guidance. Examples include Distance Measuring Equipment (DME) used in aviation, and radio beacons that transmit positional data. The core function of these apparatus is to facilitate navigation by receiving and interpreting radio signals, thereby assisting in plotting a route or identifying a location.

It is important to distinguish this category from its sibling, 8526.92, which covers radio remote control apparatus. While both fall under the broader heading of "Radar apparatus, radio navigational aid apparatus and radio remote control apparatus," 8526.91.00 focuses exclusively on aids for navigation. Radio remote control apparatus, in contrast, are designed to operate or control other devices from a distance, rather than to provide navigational information to the user.

Within this classification, two subcategories exist to further refine the classification of radio navigational aid apparatus. The first, 8526.91.00.20, applies to "Reception only apparatus," meaning these devices solely receive and process radio signals for navigational purposes and do not transmit. The second, 8526.91.00.40, is for "Other" radio navigational aid apparatus, which would include devices that may also transmit signals in conjunction with their navigational functions, or those not specifically defined as reception-only.
