HS Code for CRT monitor tube

The classification of CRT monitor tubes under HS code 8540.40 is based on their specific design as data or graphic display tubes. These components are thermionic, cold cathode, or photo-cathode valves and tubes. Unlike standard television picture tubes, these are engineered for the high-resolution output required by computer systems and professional monitors. The Harmonized System (HS) provides a specific subheading for these items to distinguish them from broadcast equipment. Specifically, 8540.40 covers both monochrome and color tubes, but for color tubes, there is a technical requirement: the phosphor dot screen pitch must be smaller than 0.4mm. This measurement is crucial because it determines the clarity and detail of the image, which is a defining characteristic of a data display tube versus a standard television tube. The classification follows General Interpretative Rules (GRI) 1 and 6. GRI 1 states that classification is determined by the terms of the headings and any relative section or chapter notes. Chapter 85 covers electrical machinery, and heading 8540 is the most specific heading for vacuum tubes. Because these are components and not the finished monitor assembly, they are correctly placed here rather than in heading 8528. Furthermore, the exclusion of these tubes from the television subheadings is a deliberate choice in the nomenclature to separate industrial and computing components from consumer electronics.

Products Included

Common Misclassification

A common error is classifying these tubes under HS code 8528, which is for complete monitors and television receivers. However, 8540.40 is strictly for the tube component itself. Another frequent mistake is using HS code 8540.11, which is reserved for color television picture tubes. The distinction lies in the phosphor dot screen pitch; if the pitch is 0.4mm or greater, it generally falls under the television category rather than the data display category. Additionally, some importers confuse these with liquid crystal display (LCD) components, which are classified under 8524 or 8529 depending on their configuration, as they do not utilize vacuum tube technology.

FAQ

What is the HS code for CRT monitor tube?

The HS code for a CRT monitor tube used for data or graphic display is 8540.40, provided it meets the technical specifications for screen pitch.

Does this code include the monitor housing?

No, HS code 8540.40 only covers the vacuum tube component. If the tube is housed within a casing with power supplies and signal inputs, it is classified as a monitor under heading 8528.
