8532.29.00.20 - Mica dielectric

This HTS classification, 8532.29.00.20, specifically covers fixed electrical capacitors that utilize mica as their dielectric material. Mica, a naturally occurring silicate mineral known for its excellent electrical insulating properties and thermal stability, forms the core insulating layer between the conductive electrodes of these capacitors. These components are crucial in various electronic circuits for filtering, smoothing, and energy storage applications where high reliability and performance are paramount.

Within the broader category of "Other fixed capacitors," this subheading is distinguished from its sibling, 8532.29.00.40, by the specific insulating material employed. While both are "other" fixed capacitors, 8532.29.00.40 would encompass fixed capacitors with dielectric materials other than mica, such as ceramic, film, or electrolytic types. The key differentiating factor for 8532.29.00.20 is the definitive presence and function of mica as the dielectric medium.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, the classification is complete for capacitors meeting the mica dielectric criterion. Importers and exporters should ensure that the capacitor's construction definitively features mica as the primary insulating layer to warrant classification under this specific subheading.
