HS Code 8541.30 – Electrical apparatus; thyristors, diacs and triacs, other than photosensitive devices
HS code 8541.30 is the 6-digit subheading for electrical apparatus, thyristors, diacs and triacs, other than photosensitive devices. It is used for silicon Controlled Rectifiers (SCRs), TRIACs, DIACs, gate Turn-Off Thyristors (GTOs) and phase control thyristors.
What HS 8541.30 covers
This category includes thyristors, DIACs, and TRIACs, which are semiconductor devices primarily used for controlling alternating current (AC) power. These components are essential in applications like light dimmers, motor speed controls, power switching, and voltage regulation in industrial and consumer electronics. International trade is driven by the demand for efficient and precise AC power management solutions across various sectors, including home appliances, industrial automation, and power tools. Importers are typically manufacturers of these end products, sourcing from specialized semiconductor component producers. Exporters are often countries with strong capabilities in power electronics manufacturing. The trade involves components critical for energy efficiency and operational control in many electrical systems.

Codes often confused with 8541.30
Common mistake. These devices are distinct from general-purpose diodes (854110) and transistors (85412x) due to their specific switching characteristics for AC power control, and from 854159 (other semiconductor devices) which covers more diverse functions.
Top exporters and importers of HS code 854130, 2025
In 2025, the largest exporter of HS code 854130 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.

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).
