Surge suppressors
Surge suppressors for circuits exceeding 1,000 volts
HSN 8535 40 30 (Surge suppressors for circuits exceeding 1,000 volts) 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. Sibling tariff lines within Chapter 85 covering switches, fuses, and lightning arresters for high-voltage circuits may carry distinct compliance obligations depending on product type and voltage rating.
The absence of compliance at this tariff line does not extend to closely related apparatus: lightning arresters and voltage limiters classified within the same subheading 8535 40, as well as low-voltage surge suppressors classified elsewhere in Chapter 85, may attract BIS Quality Control Order coverage. Re-classification by customs on examination — based on actual voltage rating, construction, or end-use — triggers retrospective compliance including detention pending the relevant licence. Verify product specifications and voltage thresholds precisely against the customs tariff before relying on the absence of compliance.
