HS Code for Display tube

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 While CRT technology has been largely superseded by flat panels, this code remains vital for the trade of specialized replacement parts and legacy industrial equipment.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.

Products Included

Common Misclassification

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.

FAQ

What is the HS code for display tube?

The HS code for data/graphic display tubes with a pitch smaller than 0.4mm is 8540.40.

Is this code used for LCD screens?

No, LCD screens are classified under heading 8524. HS code 8540.40 is exclusively for vacuum-based cathode-ray tubes.
