HS Code for Surge protector

The surge protector described by HS code 8535.40 is an industrial-grade electrical apparatus designed for high-voltage systems. Chapter 85 covers electrical machinery and equipment. Heading 8535 is specifically for electrical apparatus for switching or protecting electrical circuits, or for making connections to or in electrical circuits, for a voltage exceeding 1,000 volts. Subheading 8535.40 covers lightning arresters, voltage limiters, and surge suppressors. These devices are critical for protecting power grids and heavy industrial machinery from sudden spikes in voltage caused by lightning strikes or switching surges. Unlike consumer-grade power strips, these are heavy-duty components used in substations or large-scale electrical distributions. The classification is strictly determined by the voltage rating; if the device is rated for 1,000 volts or less, it cannot be classified here. This code is essential for the heavy electrical engineering and utility sectors.

Products Included

• High-voltage lightning arresters
• Substation surge arresters
• Transmission line voltage limiters
• Industrial surge suppressors for >1000V systems
• Gas discharge tube arresters for high-voltage protection

Common Misclassification

The most common misclassification is confusing 8535.40 with 8536.30. HS code 8536.30 is for surge suppressors and voltage limiters designed for a voltage not exceeding 1,000 volts, which includes almost all household and office surge protectors. Another error is using 8537, which covers boards, panels, and consoles equipped with two or more apparatuses of heading 8535 or 8536. If the surge protector is a standalone component for high voltage, 8535.40 is the correct designation.

FAQ

What is the HS code for Surge protector?

For industrial surge protectors and lightning arresters exceeding 1,000 volts, the HS code is 8535.40. For consumer versions under 1,000 volts, use 8536.30.

Does this code include power strips with surge protection?

Generally, no. Most power strips are rated for 110V-240V and are classified under 8536.30 or 8537.10. HS code 8535.40 is reserved for high-voltage industrial equipment.
