HS Code for Disconnector switch

The classification of a disconnector switch is determined by its technical function and operating voltage. Under the Harmonized System, electrical apparatus for switching or protecting electrical circuits are categorized under heading 8535 when the rated voltage exceeds 1,000 volts. A disconnector switch, also known as an isolator, is a mechanical switching device that provides an isolating distance in the open position. Unlike circuit breakers, disconnectors are not typically designed to interrupt high-current faults but are used to ensure a circuit is completely de-energized for maintenance or safety. Following General Interpretative Rules (GRI) 1 and 6, this product is specifically assigned to subheading 8535.30, which covers isolating switches and make-and-break switches for high-voltage applications. The classification remains consistent regardless of whether the switch is operated manually, pneumatically, or via an electric motor, provided the voltage threshold is met.

Products Included

• High-voltage air-break disconnectors
• Pantograph disconnector switches
• Load-break switches (above 1kV)
• Center-break and double-break isolators
• Earthing switches for high-voltage systems

Common Misclassification

Disconnector switches are frequently confused with those under HS code 8536.50. The primary distinction is the voltage rating; 8536 is reserved for apparatus operating at 1,000 volts or less. Additionally, they may be misclassified under 8535.21 or 8535.29, which are specifically for automatic circuit breakers. While both devices switch power, circuit breakers have an automatic trip mechanism for overcurrent protection, whereas disconnectors are primarily for isolation.

FAQ

What is the HS code for Disconnector switch?

The HS code for a disconnector switch designed for a voltage exceeding 1,000 volts is 8535.30.

Can a disconnector switch be classified under 8537?

No, HS code 8537 refers to boards, panels, and consoles equipped with two or more apparatuses of heading 8535 or 8536. An individual disconnector switch component is classified under 8535.30.
