HS Code 8541.29 – Electrical apparatus; transistors, (other than photosensitive), with a dissipation rate of 1W or more

Q: What is HS code 854129?

HS code 854129 is a 6-digit subheading in the Harmonized System that covers: Electrical apparatus; transistors, (other than photosensitive), with a dissipation rate of 1W or more. This HS code covers power transistors, which are semiconductor devices designed for high-current switching and amplification, specifically those with a power dissipation rate of 1W or more. These components are critical in applications requiring significant power handling, such as power supplies, motor control systems, automotive electronics, and industrial automation. International trade involves specialized manufacturers supplying to large-scale electronics assemblers and system integrators globally. Importers are often industries focused on heavy machinery, electric vehicles, renewable energy inverters, and high-power consumer durables. Exporters are typically advanced semiconductor producers. The demand is driven by the need for robust, efficient, and reliable power management solutions in various industrial and consumer sectors.

Q: What products fall under HS code 854129?

Power MOSFETs, IGBTs (Insulated Gate Bipolar Transistors), Power BJTs, High-current switching transistors, Audio power transistors, Voltage regulator transistors, Motor driver transistors

Q: Which countries are the top exporters of goods under HS code 854129?

In 2025, the top exporters of HS code 854129 in UN Comtrade data were China ($7.2B, 21% of world exports), Hong Kong ($6.1B) and Singapore ($4.9B). World exports came to about $34.0B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data).

Q: Which countries are the top importers of goods under HS code 854129?

In 2025, the top importers of HS code 854129 in UN Comtrade data were China ($9.5B, 27% of world imports), Hong Kong ($6.5B) and Singapore ($3.7B). World imports came to about $34.9B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

Q: How is HS code 854129 structured?

HS code 854129 is a 6-digit subheading under the Harmonized System. The first 2 digits (85) identify the chapter, digits 3-4 (41) identify the heading, and digits 5-6 (29) specify the subheading. This code is standardized globally by the World Customs Organization.

Q: What is the Brazil NCM code for HS code 854129?

Brazil splits HS code 854129 into 2 NCM codes: 8541.29.10 (Unmounted transistors of 1 W or more), 8541.29.20 (Mounted transistors of 1 W or more). The first 6 digits of each match the HS code.

HS code 8541.29 is the 6-digit subheading for electrical apparatus, transistors, (other than photosensitive), with a dissipation rate of 1W or more. It is used for power MOSFETs, IGBTs (Insulated Gate Bipolar Transistors), power BJTs, high-current switching transistors and audio power transistors.

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).
