8540.40.10.10 - Color

This HTS subcategory specifically covers color cathode-ray tubes (CRTs) designed for data or graphic displays, with a critical distinguishing feature: a phosphor dot screen pitch smaller than 0.4 mm. These tubes are employed in a variety of display devices where high resolution and detailed image reproduction are paramount, commonly found in older computer monitors and specialized display equipment. The precise measurement of the phosphor dot screen pitch is the defining characteristic for inclusion in this category, ensuring a level of visual fidelity that differentiates them from less refined display tubes.

The primary sibling category at this level, 8540.40.10.50, covers "Other" data/graphic display tubes, monochrome or color. This implies that 8540.40.10.10 is reserved for the more precise color display tubes meeting the sub-0.4 mm pitch requirement, while the sibling category encompasses a broader range of display tubes, including monochrome variants and color tubes that do not meet the stringent pitch specification. Therefore, the classification hinges on both the color capability and the specific resolution dictated by the phosphor dot screen pitch.

As this is a leaf node within the HTS, there are no further subcategories to introduce. Classification within this code is therefore dependent on the accurate identification of the product as a color cathode-ray tube for data/graphic display and confirmation that its phosphor dot screen pitch is less than 0.4 mm. Importers and exporters must ensure their documentation clearly indicates these technical specifications to facilitate accurate customs clearance.
