Product classification
HS code for Thyristor: 8541.30
Electrical apparatus, thyristors, diacs and triacs, other than photosensitive devices.
Classification of thyristor under HS 8541.30
Thyristors are classified under HS code 8541.30. This classification is determined by the nature of the device as a discrete semiconductor. According to the Explanatory Notes to the Harmonized System, heading 8541 includes semiconductor devices whose operation depends on the variation in resistivity on the application of an electric field. Thyristors, which include Silicon Controlled Rectifiers (SCRs), are four-layer semiconductor devices acting as bistable switches. They are distinct from transistors because they are designed specifically for power switching applications rather than amplification. The classification 8541.30 specifically groups thyristors, diacs, and triacs together, excluding photosensitive devices. This classification remains consistent regardless of whether the thyristor is packaged individually or in a simple module, provided it does not incorporate other active components that would transform it into an integrated circuit or a complex power module classified elsewhere.

Codes often confused with 8541.30
Common mistake. Thyristors are often misclassified under HS code 8542.39, which covers electronic integrated circuits. The key difference is that a thyristor is a discrete semiconductor device, whereas an integrated circuit contains multiple active and passive elements inseparable on a single substrate. Another common error is using HS code 8536.50 for electrical switches. While a thyristor performs a switching function, it is a solid-state semiconductor and must be classified in Chapter 8541 rather than as a mechanical or electromechanical switch.
Top exporters and importers of HS 854130 (the code used for thyristor), 2025
In 2025, the largest exporter of HS 854130 (the code used for thyristor) in UN Comtrade data was China, with 26% of world exports; the largest importer in UN Comtrade data was China, with 15% 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 854130, not only thyristor.

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).
