Data or graphic display tubes, monochrome
Monochrome data or graphic display cathode-ray tubes
HSN 8540 40 10 (Data or graphic display tubes, monochrome) 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, bill of entry, commercial invoice, packing list. Other electron valves and tubes within Chapter 85 — including television picture tubes and colour display tubes — may fall under tariff lines that carry compliance, making classification accuracy the principal importer risk.
The absence of compliance at this tariff line does not extend to the broader Chapter 85 family of thermionic valves and tubes: colour data or graphic display tubes with a phosphor dot screen pitch smaller than 0.4 mm are classified separately within heading 8540, and television picture tubes carry their own compliance history. Re-classification on customs examination triggers retrospective compliance, including detention pending the relevant clearance. Verify the display type, colour capability, and phosphor pitch against the customs tariff before relying on the absence of compliance here.
