8540.20.20.80 - Other

This HTS category, 8540.20.20.80, encompasses "Other" cathode-ray tubes. This signifies a residual category for cathode-ray tubes that do not fall under more specific classifications within this chapter. Typically, these would be cathode-ray tubes that do not primarily function as television camera tubes or as image converters and intensifiers, but rather for other specialized applications.

Distinct from its sibling category, 8540.20.20.40, which specifically designates color cathode-ray tubes, this "Other" category would include monochrome or black-and-white cathode-ray tubes, as well as those used in applications other than general television display, such as oscilloscopes, radar systems, or specialized imaging equipment where color reproduction is not the primary defining characteristic. The classification hinges on the absence of color display functionality as the main purpose.

As this node is a leaf node in the HTS structure, there are no further subcategories. Classification within this "Other" category requires careful consideration of the intended use and technical specifications of the cathode-ray tube to ensure it is not inadvertently placed in a more granular, but inapplicable, sub-heading. This catch-all provision ensures all cathode-ray tubes, not specifically itemized, are appropriately accounted for.
