HS Code for Transistor

Transistors are classified under HS code 8541.21 because they fall within the broader category of semiconductor devices. Heading 8541 specifically covers diodes, transistors, and similar semiconductor devices, as well as photosensitive semiconductor devices. The classification is determined by the physical properties and the power handling capacity of the component. Subheading 8541.21 is reserved for transistors, other than photosensitive ones, that have a power dissipation rate of less than 1 watt. This classification follows the General Rules of Interpretation (GRI) 1 and 6, which prioritize the terms of the headings and subheadings. The dissipation rate is a critical technical threshold; it refers to the amount of heat energy the device can safely dissipate during operation. If the device exceeds this 1W threshold, it moves to a different subheading. These components are essential in electronic circuits for switching and amplification, and their classification is strictly based on their electrical specifications rather than their specific application in a finished product like a computer or a radio.

Products Included

• Bipolar Junction Transistors (BJT) with dissipation < 1W
• Field-Effect Transistors (FET) with dissipation < 1W
• Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFET) with dissipation < 1W
• Small-signal transistors
• Switching transistors for low-power applications
• Junction Field-Effect Transistors (JFET)

Common Misclassification

The most frequent misclassification occurs between HS code 8541.21 and 8541.29. Code 8541.29 is used for transistors with a dissipation rate of 1 watt or more. Importers often fail to verify the technical datasheet of the component, leading to errors. Additionally, transistors are sometimes incorrectly classified under 8542.39 as integrated circuits. While an integrated circuit may contain transistors, a discrete transistor must be classified under 8541. Photosensitive transistors are also a common source of confusion; these must be classified under 8541.41 or 8541.49, regardless of their power dissipation rate.

FAQ

What is the HS code for Transistor?

The HS code for a transistor with a dissipation rate of less than 1 watt is 8541.21. If the dissipation rate is 1 watt or more, the code is 8541.29.

How is the dissipation rate determined for classification?

The dissipation rate is typically found in the manufacturer's technical specification sheet, usually measured at an ambient temperature of 25 degrees Celsius. It represents the maximum power the device can handle without damage.
