8540.40.10.50 - Other

This HTS classification covers "Other" data and graphic display tubes not specifically classified elsewhere within the 8540.40.10 subheadings. These are primarily cathode ray tubes (CRTs) designed for displaying data or graphics. The key defining characteristic for this broader grouping is that they do not fall under more specific descriptions related to color or phosphor dot pitch.

The distinguishing factor between this "Other" category and its sibling, 8540.40.10.10 (Color), is the absence of color display capability. While 8540.40.10.10 specifically addresses color display tubes, this "Other" classification encompasses monochrome display tubes or any data/graphic display tubes that, despite potentially having a color display, do not meet the stringent phosphor dot screen pitch requirements of other subheadings.

As this is a leaf node, there are no further subcategories. Therefore, classification within 8540.40.10.50 is determined by the exclusion from more specific provisions within heading 8540.40. Importers should carefully review the technical specifications of their display tubes to ensure they do not meet the criteria for color display tubes with a phosphor dot screen pitch smaller than 0.4 mm, or any other more narrowly defined subheadings within the data and graphic display tube category.
