HS Code for Photodiode

Photodiodes are classified under HS code 8541.49. This classification is part of Chapter 85, which encompasses electrical machinery and equipment. Heading 8541 is dedicated to semiconductor devices, including diodes, transistors, and similar photosensitive devices. Specifically, 8541.49 covers photosensitive semiconductor devices that are not light-emitting diodes (LEDs) and are not photovoltaic cells used for power generation. Photodiodes function by converting light into an electrical current or voltage through the photoelectric effect. The classification is based on the physical properties of the semiconductor junction and its operational role as a sensor or signal converter. This includes various types such as PIN photodiodes, avalanche photodiodes, and phototransistors when they are presented as individual components or unmounted chips. The code remains applicable regardless of whether the device is used in telecommunications, medical equipment, or consumer electronics.

Products Included

• PIN Photodiodes
• Avalanche Photodiodes (APD)
• Schottky Photodiodes
• Phototransistors
• Photosensors (semiconductor based)
• Optical detectors for fiber optic systems

Common Misclassification

Photodiodes are often misclassified under HS code 8541.41, which is specifically for light-emitting diodes (LEDs). While both are semiconductor diodes, LEDs emit light while photodiodes detect it. Another common error is using HS code 8541.42 or 8541.43, which are reserved for photovoltaic cells and modules. Although photodiodes and solar cells operate on similar principles, the latter are specifically designed to generate power, whereas photodiodes are designed for signal detection. Additionally, if a photodiode is integrated into a complex module with other active components, it might be classified under 8543.70 as an electrical machine with individual functions, depending on the complexity of the assembly.

FAQ

What is the HS code for Photodiode?

The HS code for a photodiode is 8541.49, which covers photosensitive semiconductor devices excluding LEDs and solar cells.

Are photodiodes in a fiber optic receiver classified differently?

If the photodiode is part of a complete telecommunication receiver, it may be classified under 8517.62; however, as a standalone component, it remains 8541.49.
