8529.90.43.00 - Entered with components enumerated in additional U.S. note 4 to this chapter

This HTS category, 8529.90.43.00, specifically classifies subassemblies intended for color television receivers. The defining characteristic of these subassemblies is that they must contain two or more printed circuit boards (PCBs) or ceramic substrates with components already assembled onto them. Crucially, this classification excludes tuners and convergence assemblies, even if they are part of the subassembly. The additional U.S. note 4 to Chapter 85 further refines this classification by enumerating specific components that must be present for a subassembly to fall within this heading.

Distinguishing this category from its sibling, 8529.90.46.00 (Other), is paramount for accurate classification. While the sibling category encompasses any other parts and accessories not specifically enumerated elsewhere within heading 8529, this particular subcategory is reserved for these specific multi-PCB or ceramic substrate subassemblies for color television receivers, provided they meet the component and exclusion criteria outlined. The presence of assembled components on multiple PCBs or substrates, combined with their intended use for color TV receivers, is the key differentiator.

As this category is a leaf node, there are no further subcategories. Therefore, classification into 8529.90.43.00 hinges on a thorough examination of the subassembly's physical composition, confirming the presence of two or more assembled PCBs or ceramic substrates, and verifying that it is indeed intended for color television receivers while excluding tuners and convergence assemblies as defined by the relevant additional U.S. notes.
