Product classification
HS code for Power circuit breakers: 8535.29
Electrical apparatus, automatic circuit breakers, for a voltage of 72.5kV or more.
Classification of power circuit breakers under HS 8535.29
Power circuit breakers designed for high-voltage applications are classified under HS code 853529. This code falls under heading 8535, which covers electrical apparatus for switching or protecting electrical circuits for a voltage exceeding 1,000 volts. Specifically, sub-heading 8535.29 is reserved for automatic circuit breakers that operate at a voltage of 72.5 kV or higher. These devices are critical for the protection of electrical grids and industrial power systems, as they are designed to interrupt extremely high currents during a fault or overload to prevent damage to transformers and other infrastructure. The classification is strictly determined by the rated voltage capacity of the equipment. These breakers often use specialized insulation media such as sulfur hexafluoride (SF6) gas, oil, or vacuum technology to quench the electrical arc generated during switching at high voltages.

Codes often confused with 8535.29
Common mistake. The most frequent misclassification occurs with HS code 8536.20, which is for automatic circuit breakers intended for voltages not exceeding 1,000 volts (low voltage). Another common error is using HS code 8535.21, which is specifically for circuit breakers with a voltage exceeding 1,000 volts but less than 72.5 kV. Accurate classification requires verifying the maximum rated voltage on the manufacturer's technical datasheet to distinguish between these sub-headings.
Top exporters and importers of HS 853529 (the code used for power circuit breakers), 2025
In 2025, the largest exporter of HS 853529 (the code used for power circuit breakers) in UN Comtrade data was South Korea, with 33% of world exports; the largest importer in UN Comtrade data was Saudi Arabia, with 22% 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).
