8529.90.19.40 - Of radio navigational aid apparatus (except radar) 🖩

This HTS category, 8529.90.19.40, encompasses printed circuit assemblies (PCAs) specifically designed for use with radio navigational aid apparatus, excluding radar systems. These PCAs are essential components that integrate electronic circuits, often containing microprocessors, memory, and other integrated circuits, to perform critical functions within navigational equipment. Examples include PCAs found in GPS receivers, VOR/ILS receivers, and other systems that provide position, altitude, or bearing information to aircraft, vessels, or land vehicles.

This classification is distinguished from its sibling category 8529.90.19.20, which exclusively covers printed circuit assemblies for radar apparatus. The key differentiator lies in the primary intended function of the end apparatus: navigational guidance versus detection and ranging. While both categories deal with PCAs for complex electronic equipment, the specific operational purpose of the navigational aid apparatus dictates its inclusion here.

As this is a leaf node within the HTS classification system, there are no further subcategories. Therefore, the classification relies heavily on the specific identification of the apparatus for which the printed circuit assembly is intended to be used. When classifying items under this code, it is crucial to confirm that the PCA is not designed for radar equipment or for general radio remote control apparatus, which would fall under other HTS headings.
