In a significant development for the electrical and automation industry, the Customs Authority for Advance Rulings (CAAR), Mumbai, has delivered a favorable ruling for M/s. Siemens Limited regarding the classification of parts for Vacuum Circuit Breakers (VCBs). This ruling, issued on September 3, 2025, provides clarity on the classification of these critical components under the Customs Tariff Act, 1975, and sets a precedent for similar cases in the future.
The Context: What Are Vacuum Circuit Breakers?
Vacuum Circuit Breakers (VCBs) are essential devices used in medium and high-voltage applications (1kV to 35kV) to protect electrical systems. They operate by interrupting the flow of current during faults like short circuits or overloads. The arc quenching process in VCBs occurs in a vacuum, making them highly efficient and reliable for power distribution systems.
Siemens Limited, a leader in electrification, automation, and digitalization, imports various precision-engineered parts for VCBs. These parts, made from oxygen-free copper, are designed to withstand high voltages, temperatures, and arcing conditions. To ensure compliance with customs regulations, Siemens sought an advance ruling on the classification of these parts.
