Description

Overview

Electrical apparatus for switching or protecting electrical circuits, or for making connections to or in electrical circuits, falling under HTS code 8536, encompasses a broad range of devices essential for managing and establishing electrical flow. This category is specifically designed for components operating at voltages not exceeding 1,000 volts. Its scope is distinct from other Section XVI chapters, such as Chapter 84 which covers general machinery, by focusing exclusively on electrical circuit management and connection technologies. Unlike siblings within Chapter 85 that might address power generation or signal transmission equipment, 8536 is centered on the control, protection, and interconnection of electrical circuits.

The diversity within this HTS code is reflected in its subcategories. It includes specific types of protective devices like fuses (8536.10) and automatic circuit breakers (8536.20), as well as other apparatus designed for circuit protection (8536.30). Furthermore, the category accommodates various types of relays and switches (8536.50), along with common electrical fittings such as lamp-holders, plugs, and sockets. A dedicated subcategory also exists for connectors specifically designed for optical fibers, optical fiber bundles, or cables (8536.70), highlighting the evolution of connectivity within electrical systems. Finally, a general "other apparatus" category (8536.90) captures a wide array of devices not specifically enumerated elsewhere within this heading, provided they meet the fundamental criteria of voltage limitation and intended electrical function.
