HS Code for High voltage circuit breakers
High voltage circuit breakers designed for extreme electrical loads are classified under HS code 8535.29. This specific subheading is reserved for automatic circuit breakers that operate at a voltage of 72.5 kV or higher. These are critical infrastructure components used in national power grids and large-scale industrial substations. The classification is determined by two primary factors: the device must be an "automatic" circuit breaker (capable of interrupting a circuit without manual intervention during a fault) and it must meet the 72.5 kV threshold. These breakers utilize advanced technologies such as Sulfur Hexafluoride (SF6) gas, vacuum interrupters, or air-blast mechanisms to quench the powerful electrical arcs that form when high-voltage contacts separate. The engineering complexity of these units distinguishes them from lower-voltage protective devices.
Products Included
- SF6 gas-insulated circuit breakers (72.5 kV+)

- Generator circuit breakers for large power plants
Common Misclassification
The most frequent misclassification occurs with HS code 8535.21, which is intended for automatic circuit breakers rated for more than 1,000 volts but less than 72.5 kV. Using the wrong code can lead to significant duty discrepancies. Another error is classifying these under 8535.90, which is for non-automatic switching apparatus. Furthermore, if the breaker is part of a pre-assembled switchgear unit, it may need to be classified under 8537.20 as a control panel rather than an individual component. Importers must verify the maximum rated voltage to choose between 8535.21 and 8535.29.
FAQ
What is the HS code for high voltage circuit breakers?
The HS code for automatic circuit breakers rated for 72.5 kV or more is 8535.29.
How do I distinguish between 8535.21 and 8535.29?
The distinction is based on the voltage rating; 8535.21 is for breakers between 1kV and 72.5kV, while 8535.29 is for those 72.5kV and above.
