8532.21.00.20 - Metal case 🖩

This HTS category, 8532.21.00.20, specifically classifies fixed electrical capacitors with a metal case. These capacitors utilize tantalum as a dielectric material, a characteristic that provides excellent capacitance in a small volume and good stability over a range of temperatures. The defining physical attribute for classification under this code is the presence of a metal casing, which typically serves to protect the internal components and provide electrical shielding.

This subcategory, "Tantalum," distinguishes itself from other fixed capacitors within the broader category of 8532.21.00 by its specific dielectric material. While other fixed capacitors might employ ceramic, aluminum electrolytic, or film dielectrics, this code is exclusively for those using tantalum. The "Metal case" descriptor further refines the classification by specifying the external construction, differentiating it from capacitors that might have plastic or epoxy encapsulation.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Therefore, classification under 8532.21.00.20 relies on the precise identification of a fixed capacitor that meets both the tantalum dielectric material requirement and the specified metal casing construction. Customs officers will look for these defining physical and material characteristics to ensure accurate duty assessment and trade statistics.
