Power Substation Relay and Breaker Panel
Wall-mount cabinet integrating protective relays (8536), circuit breakers (8536), and fuses (8535) for >1,000V grid protection in utility substations. HTS 8537.20.00.40 applies to such high-voltage control bases.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as individual control apparatus
Separate 8535/8536 items without panel assembly classify individually.
If sub-1,000V distribution voltage
Voltage threshold governs; low-voltage substations use different subheading.
Not sure which classification is right?
The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
