HS Code 8541.10 – Electrical apparatus; diodes, other than photosensitive or light-emitting diodes (LED)

HS code 8541.10 is the 6-digit subheading for electrical apparatus, diodes, other than photosensitive or light-emitting diodes (LED). It is used for rectifier diodes, zener diodes, schottky diodes, switching diodes and varactor diodes.

What HS 8541.10 covers

This HS code covers general-purpose diodes, which are fundamental semiconductor devices allowing current to flow in one direction. These are crucial components in nearly all electronic circuits, performing functions like rectification in power supplies, signal clamping, voltage regulation (Zener diodes), and high-speed switching. International trade in these diodes is massive, driven by the global electronics manufacturing industry. Major importers include countries with large assembly plants for consumer electronics, automotive components, and industrial machinery, such as China, Mexico, and Vietnam. Exporters are typically specialized semiconductor manufacturers in countries like Japan, South Korea, and Taiwan. Key things to know include the high volume of trade, the importance of reliability, and the continuous demand for smaller, more efficient components across diverse applications.

Codes often confused with 8541.10

Common mistake. This code is distinct from 854141 (LEDs) and 854149 (other photosensitive diodes) because it specifically excludes light-emitting and photosensitive types, focusing on standard electrical rectification and switching functions.

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).
