HS Code 85.41 – Semiconductor devices (e.g. diodes, transistors, semiconductor based transducers); including photovoltaic cells assembled or not in modules or panels, light-emitting diodes (LED) assembled with other LEDs or not, mounted piezo-electric crystals

HS code 8541 is a 4-digit heading in the Harmonized System that covers: Semiconductor devices (e.g. diodes, transistors, semiconductor based transducers); including photovoltaic cells assembled or not in modules or panels, light-emitting diodes (LED) assembled with other LEDs or not, mounted piezo-electric crystals. Heading 8541 covers semiconductor devices, the fundamental building blocks of modern electronics. This broad and critical classification includes discrete components such as diodes (rectifier, Zener, Schottky), transistors (Bipolar Junction Transistors, MOSFETs, IGBTs), and thyristors. It also explicitly covers semiconductor-based transducers, light-emitting diodes (LEDs) when assembled with other LEDs or not (as components, distinct from complete LED lamps in 8539), and photovoltaic cells (solar cells) whether or not assembled into modules or panels. Mounted piezo-electric crystals also fall under this heading. The scope is defined by the core semiconductor technology, focusing on individual devices or basic assemblies thereof, rather than complex integrated circuits (8542) or complete end-use electrical apparatus. This classification is vital for global trade, forming the backbone of virtually all electronic manufacturing. Accurate classification is paramount for managing tariffs, complying with export controls (especially for advanced components), and navigating complex global supply chains. Historically, these devices replaced vacuum tubes, enabling miniaturization and efficiency. Their inclusion in Section XVI underscores their role as essential electrical components, driving technological innovation across diverse industries from consumer electronics to renewable energy and automotive systems.

A common mistake is confusing discrete semiconductor devices (8541) with electronic integrated circuits (8542). While both are semiconductor-based, 8541 covers individual components or simple assemblies, whereas 8542 covers circuits where multiple components are integrated onto a single chip to perform a complex function (e.g., a microprocessor). Another frequent error is classifying complete LED lamps (8539) or finished solar-powered products (e.g., a solar garden light, 9405) under 8541, instead of just the individual LEDs or solar cells/panels. The key distinction for 8541 is that it covers the fundamental semiconductor devices or basic modules, not finished functional apparatus or complex integrated circuits.

In 2025, the top exporters of HS code 8541 in UN Comtrade data were China ($47.6B, 33% of world exports), Hong Kong ($16.2B) and Singapore ($11.7B). World exports came to about $146.0B, 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.

In 2025, the top importers of HS code 8541 in UN Comtrade data were China ($27.7B, 19% of world imports), Hong Kong ($17.0B) and the United States ($15.2B). World imports came to about $149.5B, 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.

HS code 8541 is a 4-digit heading under Chapter 85 of the Harmonized System. The first 2 digits (85) identify the chapter, and digits 3-4 (41) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
