HS code for Display tube: 8540.40
Tubes, data/graphic display tubes, monochrome, data/graphic display tubes, colour, with a phosphor dot screen pitch smaller than 0.4mm.
Classification of display tube under HS 8540.40
Display tubes, specifically cathode-ray tubes (CRTs) used for data or graphic displays, are classified under HS code 8540.40. This classification is found in Chapter 85, which covers electrical machinery and equipment. Heading 8540 is dedicated to thermionic, cold cathode, or photo-cathode valves and tubes. Subheading 8540.40 specifically targets monochrome or color tubes with a phosphor dot screen pitch of less than 0.4 mm. These technical specifications distinguish display tubes from standard television picture tubes. The fine pitch is necessary for the high resolution required in computer monitors, medical imaging devices, and industrial control screens. The classification is determined by the physical and technical characteristics of the tube rather than the device it is installed in. While CRT technology has been largely superseded by flat panels, this code remains vital for the trade of specialized replacement parts and legacy industrial equipment. Customs valuation and classification for these items often require technical documentation specifying the screen pitch and the intended application to ensure the 0.4 mm threshold is correctly identified.

Codes often confused with 8540.40
Common mistake. Display tubes are frequently confused with Television Picture Tubes, which are classified under HS code 8540.11 (color) or 8540.12 (monochrome). The primary difference is the screen pitch; TV tubes usually have a coarser pitch than 0.4 mm. They are also sometimes confused with flat panel modules (HS code 8524), but 8540 is strictly for vacuum tube technology.
Top exporters and importers of HS 854040 (the code used for display tube), 2025
In 2025, the largest exporter of HS 854040 (the code used for display tube) in UN Comtrade data was Singapore, with 34% of world exports; the largest importer in UN Comtrade data was Indonesia, with 14% of world imports.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
