8532.22.00.20 - Not exceeding 18 mm in diameter

This HTS category, 8532.22.00.20, specifically classifies fixed aluminum electrolytic capacitors with a diameter not exceeding 18 millimeters. These capacitors are crucial components in electronic circuits, used for storing electrical energy and smoothing out voltage fluctuations. Their small size is a defining characteristic, making them suitable for compact electronic devices and applications where space is a premium.

Distinguishing this category from its siblings is primarily based on the physical dimension of the capacitor's diameter. While all fall under fixed aluminum electrolytic capacitors, 8532.22.00.20 is reserved for those with a diameter of 18 mm or less. This contrasts with sibling categories that cover larger capacitors, specifically those exceeding 18 mm but not exceeding 35 mm (8532.22.00.40), exceeding 35 mm but not exceeding 51 mm (8532.22.00.55), and exceeding 51 mm in diameter (8532.22.00.85). The diameter serves as the sole determinant for classification within this group.

As a leaf node within the HTS, this category does not have further subcategories. Therefore, the classification is precise and based solely on the product being a fixed aluminum electrolytic capacitor with a diameter not exceeding 18 mm. When classifying, users should confirm the material composition (aluminum electrolytic) and the specified diameter to ensure accurate entry under this HTS code.
