Monochrome cathode-ray tubes for television receivers
HSN 8540 12 00 (monochrome cathode-ray tubes) 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 thermionic, cold-cathode, or photo-cathode valves and tubes under Chapter 85 — particularly colour cathode-ray tubes and certain electronic display components — may carry distinct compliance obligations at their respective tariff lines.
The principal risk at this tariff line is misclassification: colour cathode-ray tubes, television camera tubes, and other electron-beam devices classified separately within Chapter 85 may attract BIS or other compliance that does not extend to monochrome cathode-ray tubes. Customs re-classification on examination — for instance, where a tube is found to be a colour-capable device — triggers retrospective compliance and potential detention pending the applicable licence. Verify the technical specification against the customs tariff description before relying on the absence of compliance here.
