Last updated: August 2026 dataServing as the catch-all heading for high-voltage switching and circuit-protection equipment not elsewhere specified, this category captures specialized apparatus used in power distribution networks, industrial plants, and grid-scale energy projects where operating voltages exceed 1,000 V. The 'not elsewhere specified' (NES) qualifier means classification here is appropriate only after ruling out more specific headings — a determination that often requires detailed technical specifications and, for complex assemblies, a binding ruling request. Section 301 tariffs may apply to Chinese-origin goods in this space, making origin documentation especially important.

Importers should provide manufacturer technical datasheets confirming the rated voltage exceeds 1,000 V, a functional description demonstrating the device is not a fuse, circuit breaker, relay, or other specifically enumerated type, and, where ambiguity exists, a binding ruling from CBP. Engineering drawings or IEC/ANSI certification records can also support the classification.
Combination units are generally classified by the component that imparts the essential character of the assembly. If no single function dominates, the heading that appears last in numerical order among the competing classifications typically applies under GRI 3(c). A licensed customs broker or a CBP binding ruling is advisable for complex multi-function assemblies.
