8504.90.20.00 - Printed circuit assemblies

This HTS classification, 8504.90.20.00, specifically designates "Printed circuit assemblies" as components. These assemblies are fundamental to modern electronic devices, comprising a board with conductive pathways, pads, and other features etched or printed onto it, designed to connect various electronic components. This category is distinguished from its sibling, 8504.90.41.00 (Other parts), by the specific nature of the component being a *printed circuit assembly*. While "Other" encompasses a broad range of parts not otherwise specified, this code isolates those parts that are specifically designed as integrated circuits on a printed board.

The "Printed circuit assemblies" classified under 8504.90.20.00 are intended for use as parts within the broader scope of electrical transformers, static converters, and inductors. The parent categories indicate that these assemblies are primarily associated with power supplies for automatic data processing machines, certain printers and monitors, or projectors. Therefore, while the assemblies themselves are standardized electronic components, their classification here is tied to their intended application within specific types of power supply units.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. The classification is definitive for printed circuit assemblies fitting the described context. Classification hinges on the presence of a manufactured board with integrated circuitry designed for a specific function within the aforementioned power supply applications.
