8540.20.20.40 - Color

This HTS category, 8540.20.20.40, specifically covers color cathode-ray tubes. These tubes are designed for the display of images in color and are characterized by their internal phosphors that emit different colored light when struck by an electron beam, creating a full-spectrum visual output. They are integral components in older television sets and monitors.

This classification is distinguished from its sibling category, 8540.20.20.80, which encompasses "other" cathode-ray tubes. The sibling category would include cathode-ray tubes not designed for color display, such as monochrome tubes used in specialized applications like oscilloscopes or older black-and-white televisions. The key differentiator lies in the internal construction and intended function for color reproduction.

As a leaf node in the HTS structure, this category does not have further subdivisions. Classification within 8540.20.20.40 is therefore determined by the primary characteristic of the cathode-ray tube being a color display device. Practical classification relies on verifying the tube's design and technical specifications for color image generation, distinguishing it from monochromatic counterparts or other types of electron beam tubes.
