HS Code for Power transistor

Power transistors are classified under HS code 854129. This code is found in Chapter 85, which covers electrical machinery and equipment. Heading 8541 is designated for semiconductor devices, such as diodes, transistors, and similar semiconductor devices. Transistors are further subdivided based on their power dissipation capabilities. Subheading 854129 specifically covers transistors, other than photosensitive transistors, that have a power dissipation rate of 1 watt or more. These "power" versions are typically used in power supplies, motor controllers, and amplification stages where they must handle significant current and voltage. The classification is based on the physical properties of the semiconductor and its rated thermal dissipation. If a transistor is part of an integrated circuit, it would be classified elsewhere, but as a discrete component with a dissipation rate of 1W or higher, 854129 is the correct designation. This code is essential for identifying components used in power electronics rather than low-signal logic or processing applications.

Products Included

• Power MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors)
• IGBTs (Insulated Gate Bipolar Transistors)
• Bipolar Power Transistors (BJT)
• Darlington pairs with dissipation > 1W
• Gallium Nitride (GaN) power transistors

Common Misclassification

A common misclassification occurs with HS code 854121, which is for transistors with a power dissipation rate of less than 1 watt. Importers often overlook the dissipation rating in the technical specs. Another error is using 854141 or 854149, which are for photosensitive transistors or LEDs. Furthermore, if the transistor is integrated into a module with other components like diodes or ICs, it might be misclassified as an Integrated Circuit under 854231, though discrete power transistors remain in 854129.
