8542.90.00.00 - Parts

This HTS category, 8542.90.00.00, is designated for "Parts" specifically related to electronic integrated circuits. This encompasses a wide array of components that are integral to the functioning or repair of such circuits, but which are not complete integrated circuits themselves. Examples include substrates, encapsulating materials, leads, connecting wires, and any other elements that, when assembled or integrated, form part of a larger electronic integrated circuit. The classification hinges on the item's specific function as a constituent element of an integrated circuit, rather than its standalone capability.

This category is distinguished from its sibling, 8542.30, which covers "Electronic integrated circuits" themselves. While 8542.30 deals with the fully functional, assembled integrated circuits, 8542.90.00.00 focuses exclusively on the constituent parts and components that make up those circuits. Therefore, an item would be classified here if it is designed to be incorporated into an integrated circuit, but does not, on its own, perform the logic or memory functions characteristic of a complete integrated circuit.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification within 8542.90.00.00 requires a thorough understanding of the specific physical and functional characteristics of the part in question, and its direct relationship to the assembly or manufacturing of electronic integrated circuits. The key is to determine if the part is exclusively or principally designed for use in the construction, assembly, or repair of electronic integrated circuits.
