Rheostats
Rheostats, wire-wound, power handling not exceeding 20 W
HSN 8533 31 20 (Rheostats, for a power handling capacity not exceeding 20 W) 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 electrical resistors and potentiometers within Chapter 85 — particularly heating resistors or higher-wattage variable resistors — may fall under tariff lines that carry compliance obligations, making classification accuracy the principal importer risk.
The absence of compliance at this tariff line does not extend across Chapter 85: wire-wound variable resistors for higher power ratings, fixed carbon or metal-film resistors, and heating resistors are each separately classified and may attract distinct regulatory treatment. Re-classification by customs on examination — for example, from a non-heating variable resistor to a heating resistor — triggers retrospective compliance and potential detention pending resolution. Confirm the product's power rating, constructional type, and intended end-use against the customs tariff schedule before relying on the absence of compliance here.
