8532.30.00.90 - Other

This HTS category, 8532.30.00.90, encompasses "Other" variable or adjustable capacitors. It serves as a residual classification for these types of capacitors when they do not fit into the more specific subcategories defined by their dielectric material. Variable and adjustable capacitors are designed to have their capacitance value changed either manually by the user (variable) or set to a specific value during manufacturing or servicing (adjustable or pre-set). They are essential components in electronic circuits for tuning, filtering, and oscillation.

This node is distinct from its sibling, 8532.30.00.10, which specifically covers variable or adjustable capacitors with mica, ceramic, or glass dielectrics. Therefore, 8532.30.00.90 applies to variable or adjustable capacitors that utilize other dielectric materials, such as plastic films (e.g., polyester, polypropylene), electrolytic materials, or air. The key differentiating factor is the material used as the insulator between the conductive plates, which directly influences the capacitor's electrical characteristics and applications.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification within this heading hinges on a thorough examination of the capacitor's construction, particularly the dielectric medium, to ensure it is not specifically provided for elsewhere. If a variable or adjustable capacitor's dielectric material is not mica, ceramic, or glass, it will be classified under this "Other" designation.
