Of nichrome
Nichrome fixed resistors, power handling not exceeding 20 W
HSN 8533 21 21 (fixed resistors of nichrome, rated 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 passive electronic components within Chapter 85 may fall under sibling tariff lines that do carry compliance obligations; classification accuracy is the principal importer risk.
The absence of compliance at this tariff line does not extend across Chapter 85 broadly: certain fixed and variable resistors classified at other headings within the same chapter attract BIS Quality Control Order requirements, and re-classification on customs examination triggers retrospective compliance, including detention pending the relevant conformity certificate. Verify the resistor material, power rating, and intended application against the customs tariff before relying on the absence of compliance at this line.
