Product classification
HS code for Semiconductor sensor: 8541.51
Electrical apparatus, photosensitive semiconductor devices, semiconductor-based transducers.
Classification of semiconductor sensor under HS 8541.51
Semiconductor sensors are classified under HS code 8541.51. This classification is applied because the devices are semiconductor-based transducers that convert a physical phenomenon into an electrical signal. Under the 2022 HS nomenclature updates, the scope of heading 8541 was expanded to explicitly include semiconductor-based transducers. These are defined as components whose operation is based on the properties of semiconductor materials and which perform the function of a sensor or actuator. To fall under 8541.51, the sensor must be a discrete component or a multi-component integrated circuit (MCO) that utilizes semiconductor technology to detect changes in the environment, such as pressure, acceleration, or magnetic fields. The classification depends on the physical construction of the device; it must be a semiconductor device rather than a complex instrument or assembly that incorporates a sensor.

Codes often confused with 8541.51
Common mistake. Semiconductor sensors are often misclassified under Chapter 90, specifically HS code 9025 (thermometers), 9026 (flow/pressure meters), or 9031 (measuring and checking instruments). The distinction lies in whether the item is a finished measuring instrument or a discrete semiconductor component. If the product is a basic transducer that requires external circuitry to provide a readable output, it belongs in 8541.51. If it is a complete instrument with a display or calibrated output for a specific application, it may fall under Chapter 90. Additionally, photosensitive sensors are classified under 8541.41 to 8541.49 rather than 8541.51.
Top exporters and importers of HS 854151 (the code used for semiconductor sensor), 2025
In 2025, the largest exporter of HS 854151 (the code used for semiconductor sensor) in UN Comtrade data was Germany, with 30% of world exports; the largest importer in UN Comtrade data was China, with 24% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 854151, not only semiconductor sensor.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).
