Product classification
HS code for Power transistor: 8541.29
Electrical apparatus, transistors, (other than photosensitive), with a dissipation rate of 1W or more.
Classification of power transistor under HS 8541.29
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.

Codes often confused with 8541.29
Common mistake. 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.
Top exporters and importers of HS 854129 (the code used for power transistor), 2025
In 2025, the largest exporter of HS 854129 (the code used for power transistor) in UN Comtrade data was China, with 21% of world exports; the largest importer in UN Comtrade data was China, with 27% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
