HS Code for Optocoupler

Optocouplers, also known as opto-isolators, are classified under HS code 8541.59. Heading 8541 covers semiconductor devices, including diodes, transistors, and photosensitive semiconductor devices. An optocoupler is a component that transfers electrical signals between two isolated circuits by using light. It typically consists of a light-emitting diode (LED) and a photosensitive device (such as a phototransistor) integrated into a single package. While it contains an LED, its primary function is that of a semiconductor switching or isolating device rather than a simple light source. Under the 2022 HS revisions, photosensitive semiconductor devices are categorized within 8541. The sub-heading 8541.59 is used for 'other' semiconductor devices that do not fit into the specific categories of transistors or simple diodes, capturing the integrated nature of the optocoupler's input and output stages.

Products Included

Common Misclassification

Optocouplers are frequently misclassified under HS code 8541.41, which is specifically for Light Emitting Diodes (LEDs). While an optocoupler contains an LED, the presence of the photosensitive receiver makes it a more complex semiconductor device. Another common error is 8517.62, which covers telecommunication switching apparatus. While optocouplers are used in telecom equipment, as individual components, they must be classified by their physical nature in 8541. Finally, they should not be confused with integrated circuits (8542), as optocouplers are generally considered discrete semiconductor assemblies rather than monolithic ICs.

FAQ

What is the HS code for optocoupler?

The correct HS code for an optocoupler is 8541.59, as it is a photosensitive semiconductor device.

Are optocouplers classified as integrated circuits?

Generally, no. Optocouplers are classified as semiconductor devices under 8541 because they consist of discrete components (LED and photodetector) combined in one package, rather than a single monolithic chip.
