For a voltage of 400 kV
High-voltage switching and protection apparatus rated at 400 kV
HSN 8535 29 23 (electrical switching and protection apparatus for a voltage of 400 kV) is not covered by a Bureau of Indian Standards Quality Control Order and carries no Partner Government Agency clearance requirement at the tariff-line level. Import follows the standard customs procedure: Importer-Exporter Code (IEC), bill of entry, commercial invoice, packing list. Other apparatus within Chapter 85 — particularly switching equipment rated at voltages below 400 kV or apparatus intended for distinct circuit-protection functions — may fall under sibling tariff lines that carry compliance obligations.
The absence of compliance at this tariff line does not extend across the broader Chapter 85 switching and protection apparatus family; certain voltage-rated switchgear classifications are subject to BIS Quality Control Orders, and a customs officer who re-characterises the voltage rating or functional category of the goods can trigger retrospective compliance, including detention pending applicable certification. Verify the rated voltage, switching function, and intended installation context against the customs tariff schedule before treating this tariff line as definitively applicable.
