About HS Code 853529
This category encompasses extra-high voltage (EHV) and ultra-high voltage (UHV) automatic circuit breakers, specifically for systems operating at 72.5 kilovolts or more. These massive and sophisticated devices are indispensable components of national power grids, large transmission substations, and major renewable energy integration projects. Their primary function is to safely interrupt enormous fault currents at extremely high voltages, thereby ensuring grid stability, preventing widespread outages, and protecting critical infrastructure. Importers are typically national power utilities, large-scale energy project developers, and heavy industry. Exporters are a limited number of highly specialized global manufacturers. Reliability, breaking capacity, and environmental considerations (e.g., SF6 gas management) are paramount in the trade of these high-value, critical components.
Products Under This Code
