For a voltage of 400 kV
Electrical switching or protection apparatus rated at 400 kV
HSN 8535 29 13 (electrical switching or protection apparatus for voltages exceeding 1,000 V, rated at 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, bill of entry, commercial invoice, packing list. Other electrical switching and protection apparatus within Chapter 85 — particularly lower-voltage switchgear — may fall under tariff lines that do carry BIS compliance obligations.
The absence of compliance at this tariff line does not extend to sibling lines within heading 8535 or the broader Chapter 85 switchgear family: lower-voltage apparatus and certain categories of surge suppressors, voltage limiters, and lightning arresters classified elsewhere in the heading may attract BIS Quality Control Order obligations. Customs re-classification — for instance, from a 400 kV-rated line to a line covering a lower voltage range — triggers retrospective compliance, including detention pending the relevant certification. Confirm the rated voltage and apparatus type precisely against the customs tariff before shipment.
