8529.90.16.20 - Of radar apparatus

This HTS classification, 8529.90.16.20, specifically covers printed circuit assemblies that are designed for use with radar apparatus. These assemblies are integral components, meaning they consist of two or more parts or pieces fastened or joined together, forming a functional unit. The defining characteristic for inclusion in this category is the intended primary application of the printed circuit assembly within radar systems, which are used for detecting objects by means of radio waves.

Distinction from sibling categories is crucial for accurate classification. While 8529.90.16.40 also covers printed circuit assemblies within the broader heading of parts for apparatus of headings 8524 to 8528, it is specifically for radio navigational aid apparatus *except* radar. Therefore, assemblies intended for altimeters, glide slope receivers, or other non-radar navigation aids would fall under that sibling category. Category 8529.90.16.60, "Other," is reserved for printed circuit assemblies that do not meet the specific criteria for radar or other radio navigational aids within this group.

As a leaf node, this classification does not have further subdivisions. The classification is determined by the specific function and intended use of the printed circuit assembly with radar equipment. Examples include radar processing units, display driver assemblies for radar screens, or power supply modules specifically engineered for radar systems, provided they are assemblies of two or more joined components and not single integrated circuits.
