8529.90.19 - Other

This category, HTS Code 8529.90.19, encompasses "Other" printed circuit assemblies that are suitable for use with apparatus of headings 8524 to 8528. Specifically, it includes printed circuit assemblies (PCAs) that are not specifically covered by the sibling category, 8529.90.16, which pertains to assemblies and subassemblies composed of two or more interconnected parts. The scope of 8529.90.19 is therefore for PCAs that serve as critical components within a broader range of electronic equipment, including those for recording and reproducing sound, images, and for various communication and navigation functions.

Unlike its sibling, 8529.90.16, which focuses on the structural assembly of multiple parts, this category is defined by the function and ultimate application of the printed circuit assembly. The PCAs classified here are designed to perform specific electronic functions within larger apparatus, acting as the functional core or a significant processing unit for that apparatus. Therefore, the classification hinges on the intended end-use of the PCA rather than its method of physical construction, provided it doesn't fall under more specific subheadings.

The subcategories within 8529.90.19 further refine the classification based on the type of apparatus the printed circuit assembly is intended for. This includes specific provisions for PCAs used in radar apparatus (8529.90.19.20), those used in radio navigational aid apparatus excluding radar (8529.90.19.40), and a residual category for all other PCAs falling under this heading but not specifically enumerated in the preceding subcategories (8529.90.19.60). This hierarchical structure allows for precise classification of components based on their specialized role within advanced electronic systems.
