8506.90.00.00 - Parts

HTS Code 8506.90.00.00, categorized under "Parts," encompasses components specifically designed for use with primary cells and primary batteries of heading 8506. This includes a wide array of items such as casings, separators, electrodes, terminals, and other internal or external structural elements that, while not primary batteries themselves, are integral to their construction and function. The classification hinges on these items being exclusively or predominantly used with primary batteries.

This residual category for "Parts" is distinguished from the preceding sibling categories (8506.10 through 8506.60) which are defined by the specific active materials or types of primary cells and batteries themselves. For instance, while 8506.10 classifies primary batteries utilizing manganese dioxide, 8506.90 would cover components like plastic battery holders or metal connectors intended for use in those or any other primary battery types within heading 8506.

As this is a leaf node within the HTS structure, there are no further subcategories under 8506.90.00.00. Classification within this heading requires careful consideration of the intended application of the part; if a component is not a primary battery or a specific type of primary battery listed in the preceding subheadings, but is clearly intended for the manufacture, repair, or maintenance of such batteries, it will be classified here.
