Product classification
HS code for Rectifier diode: 8541.10
Electrical apparatus, diodes, other than photosensitive or light-emitting diodes (LED).
Classification of rectifier diode under HS 8541.10
Rectifier diodes are classified under HS code 854110 because they are discrete semiconductor devices whose primary function is to conduct current in a single direction, a process known as rectification. This code is situated within Chapter 85, which covers electrical machinery and equipment. Specifically, heading 8541 is dedicated to diodes, transistors, and similar semiconductor devices. The sub-heading 10 is precise in its scope, identifying diodes that are neither photosensitive nor light-emitting. These components are fundamental in power electronics for converting alternating current (AC) into direct current (DC). The classification is determined by the physical properties of the semiconductor material, typically silicon or germanium, and the presence of a P-N junction. According to the General Rules for the Interpretation of the Harmonized System (GRI), products are classified based on their objective characteristics at the time of importation. Since these diodes are finished electronic components intended for rectification, they meet the criteria for 854110. This code excludes complex integrated circuits, which are found under 8542, and focuses on the individual semiconductor unit.

Codes often confused with 8541.10
Common mistake. A frequent point of confusion occurs between HS code 854110 and HS code 854141, which covers light-emitting diodes (LEDs). While both are diodes, the functional application and physical construction differ; 854110 is for power rectification, whereas 854141 is for light emission. Another common error involves HS code 854121, which is reserved for transistors. Importers often confuse these because they may share similar small-signal packages. Furthermore, if a diode is part of a pre-assembled bridge rectifier module, it might be classified under 850440 as a static converter.
Top exporters and importers of HS 854110 (the code used for rectifier diode), 2025
In 2025, the largest exporter of HS 854110 (the code used for rectifier diode) in UN Comtrade data was Hong Kong, with 23% of world exports; the largest importer in UN Comtrade data was China, with 21% 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 854110, not only rectifier diode.

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).
