HS Code:
The Zener category, typically classified under HS Code 8541.10 (Diodes, including Zener diodes, other than photosensitive or light-emitting diodes), encompasses semiconductor devices primarily used for voltage regulation and protection in electronic circuits. Zener diodes are crucial components in power supplies, voltage reference circuits, and overvoltage protection systems, widely utilized in industries such as telecommunications, automotive, consumer electronics, and industrial automation. Global trade in this category reflects the growing demand for electronic components driven by advancements in technology and the increasing adoption of smart devices and renewable energy systems.
