8543.90.68.00 - Other

This classification, HTS 8543.90.68.00, covers printed circuit assemblies that are not specifically enumerated in preceding subheadings within the "Parts" category of heading 8543. It represents a residual classification for printed circuit assemblies that do not fit into more specific descriptions, such as those intended for flat panel displays other than those found in specific television articles. The key criterion for inclusion here is that the printed circuit assembly performs an individual function within a larger electrical machine or apparatus, and its specific application or design prevents its classification under more precise subheadings.

This category is distinguished from its sibling, 8543.90.65.00, by the exclusion of printed circuit assemblies specifically designed for flat panel displays, unless those displays are intended for articles of heading 8528, and further excluding those for subheadings 8528.52 or 8528.62. Therefore, if a printed circuit assembly is not for a flat panel display covered by the sibling, or if it is for an excluded type of flat panel display, it may fall under this broader "Other" printed circuit assembly category.

As a leaf node, HTS 8543.90.68.00 has no further subcategories. Classification within this code requires careful consideration of the printed circuit assembly's specific design, intended use, and the overall electrical apparatus it is a part of, ensuring it does not meet the criteria for any more specific part classification within heading 8543 or related headings.
