About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This HTS subheading, 8541.10.00.50, specifically covers Zener diodes. Zener diodes are a type of semiconductor diode designed to conduct electricity in the reverse direction when a certain breakdown voltage (the Zener voltage) is reached. This characteristic makes them invaluable for voltage regulation and voltage reference applications. Unlike standard diodes that are primarily intended for rectification, Zener diodes are engineered to maintain a stable voltage across their terminals once the Zener voltage is exceeded, making them distinct in their operational purpose and design.

This classification distinguishes Zener diodes from their sibling category, 8541.10.00.60, which is designated for microwave diodes. Microwave diodes are optimized for high-frequency applications in the microwave spectrum and have differing construction and performance characteristics compared to Zener diodes. The "Other" designation at this level encompasses a broad range of other diode types not specifically enumerated, emphasizing the precise categorization required for Zener diodes within this structure.

As this is a leaf node, there are no further subcategories under 8541.10.00.50. The classification is therefore highly specific to Zener diodes, and further subdivision is not required. Classification into this category hinges on the diode's intended function as a voltage regulator or reference, its specific electrical characteristics related to reverse breakdown voltage, and its semiconductor composition.
