NO PGA · STANDARD CUSTOMS PROCEDURE

HSN 8540 79 00 (other thermionic, cold cathode, or photo-cathode 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. Cathode-ray tubes, television camera tubes, and other specifically enumerated valve and tube types within heading 8540 occupy their own tariff lines and may carry distinct compliance obligations.

No partner government agency notification covers this tariff line.
A word of counsel

Heading 8540 spans a wide range of electronic valves and tubes, several of which are classified at more specific tariff lines that do carry compliance — cathode-ray tubes and magnetrons are common reclassification targets on customs examination. A reclassification to a more specific line within Chapter 85 triggers retrospective compliance, including potential detention pending the applicable conformity requirement. Verify product specification — tube type, operating principle, and end-use — against the customs tariff before relying on the absence of compliance at this residual line.
