HS Code 8540.40 – Tubes; data/graphic display tubes, monochrome; data/graphic display tubes, colour, with a phosphor dot screen pitch smaller than 0.4mm

HS code 8540.40 is the 6-digit subheading for tubes, data/graphic display tubes, monochrome, data/graphic display tubes, colour, with a phosphor dot screen pitch smaller than 0.4mm. It is used for high-resolution color CRT monitors, monochrome data display CRTs, CAD workstation CRTs, medical diagnostic display CRTs and air traffic control display CRTs.

What HS 8540.40 covers

This HS code covers cathode-ray tubes specifically designed for data and graphic display, including both monochrome and high-resolution color tubes with a phosphor dot screen pitch smaller than 0.4mm. These tubes were once the backbone of computer monitors, CAD workstations, and high-end graphic displays, prized for their superior color accuracy and refresh rates compared to early flat panels. While largely replaced by LCDs and OLEDs in consumer markets, they still find niche applications in specialized industrial, medical, and legacy professional systems where specific display characteristics or robustness are required. Importers include specialized electronics distributors, repair services, and manufacturers of industrial control systems. Exporters are typically countries with residual CRT manufacturing capabilities or those involved in component refurbishment. The trade volume has significantly declined, focusing on replacement parts and specialized applications.

Codes often confused with 8540.40

Common mistake. This code should not be confused with 852852 (other monitors, not incorporating television reception apparatus, color) or 852859 (other monitors, not incorporating television reception apparatus, monochrome), as 854040 refers to the tube component itself, not the complete monitor.

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).
