Receiver or amplifier valves and tubes
Receiver or amplifier thermionic valves and tubes
HSN 8540 81 00 (receiver or amplifier valves and 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 tubes within Chapter 85 — such as cathode-ray tubes or television camera tubes — may fall under separate tariff lines that carry distinct compliance obligations.
The principal importer risk at this tariff line is misclassification: valves and tubes serving display, rectification, or imaging functions are separately classified within heading 8540 and may attract compliance regimes that do not apply here. A customs re-classification on examination triggers retrospective compliance, including detention pending the relevant clearance. Verify the functional specification — amplification or reception versus display or rectification — against the customs tariff before declaring under this line.
