Voltage limiters
Voltage limiters for circuits exceeding 1,000 volts
HSN 8535 40 20 (Voltage limiters for electrical 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 lightning arresters and surge suppressors may attract distinct compliance; classification accuracy is the principal importer risk.
The absence of compliance at this tariff line does not extend to neighbouring lines within heading 8535: lightning arresters and surge suppressors are separately classified and may carry their own compliance obligations. Re-classification on customs examination — for instance, where a device functions as a surge suppressor rather than a dedicated voltage limiter — triggers retrospective compliance, including detention pending the relevant clearance. Verify the device's functional specification and rated operating voltage against the customs tariff before relying on the absence of compliance.
