Data or graphic display tubes, colour, with a phosphor dot screen pitch smaller than 0.4 mm
Colour data or graphic display tubes, phosphor dot pitch under 0.4 mm
HSN 8540 40 20 (colour data or graphic display tubes with a phosphor dot screen pitch smaller than 0.4 mm) 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 cathode-ray tubes, television camera tubes, and display valves classified elsewhere in Chapter 85 may carry distinct compliance obligations depending on their intended application.
The principal importer risk here is misclassification: monochrome data or graphic display tubes, colour tubes with a phosphor dot pitch of 0.4 mm or greater, and television picture tubes are each classified under separate tariff lines within Chapter 85, some of which attract compliance. A customs re-classification on examination can trigger retrospective compliance and detention pending resolution. Verify phosphor dot screen pitch and intended use against the tariff specification before filing the bill of entry.
