8534.00.00.40 - Other

This HTS subcategory, "Other" under HTS code 8534.00.00.40, encompasses printed circuits that are not specifically covered by other more granular classifications within heading 8534. Specifically, it applies to printed circuits whose base is wholly of impregnated glass and that do not possess three or more layers of conducting materials. This residual category ensures that all printed circuits meeting the general description of heading 8534, and whose base is impregnated glass, are appropriately classified, even if they don't fit into more specialized subheadings.

The primary distinction for this category lies in the number of conducting material layers. While other subcategories might detail printed circuits with a specific count of layers, 8534.00.00.40 serves as the catch-all for those with fewer than three layers of conducting materials, provided they also meet the base material requirement of wholly impregnated glass. This ensures that printed circuits are classified based on their structural complexity and material composition.

As this is a leaf node within the HTS, there are no further subcategories that break down this classification. Therefore, the classification decision for goods falling under 8534.00.00.40 hinges on confirming that the item is indeed a printed circuit, that its base is entirely composed of impregnated glass, and that it does not exhibit three or more distinct layers of conducting materials.
