8526.91.00.40 - Other 🖩

This HTS category, 8526.91.00.40, encompasses "Other" radio navigational aid apparatus. It serves as a residual category for devices designed to assist in navigation through the use of radio signals that do not fall under more specific subheadings within the 8526.91.00 designation. These apparatus are crucial for determining position, course, or speed by receiving and processing radio signals from established navigational beacons, satellites, or other transmitting sources. Examples may include specialized ground-based or airborne radio receivers used in conjunction with navigational systems that are not solely reception-only devices.

Distinguishing this category from its sibling, 8526.91.00.20 (Reception only apparatus), is key. While the sibling category exclusively covers devices that *only* receive radio signals for navigational purposes, 8526.91.00.40 is intended for radio navigational aid apparatus that may perform additional functions beyond mere reception, such as transmission, processing, or integration with other navigational systems. The defining characteristic is its role in aiding navigation via radio waves, with the "Other" designation pointing to items not otherwise specifically enumerated within this sub-level.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification under this heading relies heavily on the primary function of the apparatus being radio navigational aid, and its exclusion from more specific categories at the same or higher levels of the tariff schedule. Customs professionals should examine the technical specifications and intended use of the equipment to ensure accurate classification.
