HS Code 8541.51 – Electrical apparatus; photosensitive semiconductor devices, semiconductor-based transducers
HS code 8541.51 is the 6-digit subheading for electrical apparatus, photosensitive semiconductor devices, semiconductor-based transducers. It is used for MEMS accelerometers, MEMS gyroscopes, semiconductor pressure sensors, hall effect sensors and thermistors (semiconductor type).
What HS 8541.51 covers
This specific code covers semiconductor-based transducers, which are devices that convert various physical quantities (such as pressure, temperature, acceleration, or magnetic fields) into electrical signals using semiconductor properties. These are highly specialized components essential for advanced sensing applications in automotive systems, medical devices, industrial control, and consumer electronics (e.g., MEMS sensors in smartphones). International trade involves high-value, precision components, often sourced from specialized manufacturers by system integrators and product developers globally. The market is driven by the increasing demand for smart devices, automation, and IoT, requiring accurate and reliable sensing capabilities for complex systems. Exporters are typically countries with advanced semiconductor R&D and manufacturing capabilities.

Codes often confused with 8541.51
Common mistake. This code is distinct from other photosensitive devices (85414x) as it focuses on transducers converting various physical phenomena, not just light, into electrical signals, and from 9026 (instruments for measuring flow, level, pressure, etc.) which covers complete instruments rather than just the semiconductor sensing element.
Top exporters and importers of HS code 854151, 2025
In 2025, the largest exporter of HS code 854151 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.

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).
