Heading 8535

Electrical apparatus for switching or protecting electrical circuits, or for making connections to or in electrical circuits (for example, switches, fuses, lightning arresters, voltage limiters, surge suppressors, plugs and other connectors, junction boxes), for a voltage exceeding 1,000 V

12 declarable lines

Heading 8535 covers high-voltage electrical apparatus used to switch, protect, or connect circuits, meaning apparatus rated above 1,000 V. It is split first by article type: fuses, automatic circuit breakers, isolating and make-and-break switches, lightning arresters and surge suppressors, and a residual other group. The other group separates motor starters and overload protectors from terminals, splices, couplings, and other connectors.

Products in this heading

High-voltage fuses rated for circuits of 2,300 V or more
High-voltage fuses for other circuits above 1,000 V
Automatic circuit breakers rated below 72.5 kV
Automatic circuit breakers for circuits of 345 kV or more
High-voltage knife isolating switches
Lightning arresters and surge suppressors
High-voltage motor starters and motor overload protectors
High-voltage terminals, electrical splices and couplings

How to choose the right subheading

Confirm the apparatus is rated for a voltage exceeding 1,000 V.
Identify the article type: fuse, automatic circuit breaker, isolating or make-and-break switch, lightning arrester or surge suppressor, or other.
For fuses, check whether the circuit is 2,300 V or more or other; for breakers, check whether the voltage is less than 72.5 kV or other and whether the circuit is 345 kV or more.
For isolating and make-and-break switches, check whether the switch is knife type or other.
For other apparatus, separate motor starters and overload protectors from terminals, splices, couplings, other connectors, and residual other.

Frequently asked questions

What is the HTS code for high-voltage fuses?

Fuses for circuits of 2,300 V or more go in 8535.10.00.20 at a general (MFN) rate of 2.7%. Other fuses above 1,000 V go in 8535.10.00.40 at a general (MFN) rate of 2.7%.

What is the duty on high-voltage automatic circuit breakers?

Automatic circuit breakers for less than 72.5 kV go in 8535.21.00.00 at a general (MFN) rate of 2.7%. Other breakers in circuits of 345 kV or more go in 8535.29.00.20 at a general (MFN) rate of 2%, and other breakers go in 8535.29.00.40 at a general (MFN) rate of 2%.

How do I classify high-voltage surge suppressors or motor starters?

Lightning arresters, voltage limiters and surge suppressors go in 8535.40.00.00 at a general (MFN) rate of 2.7%. Motor starters and motor overload protectors for over 1,000 V go in 8535.90.40.00 at a general (MFN) rate of 2.7%.
