8540.12.10.00 - Non-high definition

This HTS category encompasses monochrome cathode-ray television picture tubes and video monitor cathode-ray tubes that fall within a specific size range. Specifically, these tubes are characterized by a straight-line dimension across their faceplate that exceeds 29 centimeters but does not exceed 42 centimeters. The "non-high definition" designation signifies that these tubes are not designed for displaying ultra-high resolution imagery, differentiating them from their high-definition counterparts.

The primary distinction between this category (8540.12.10.00) and its sibling category (8540.12.20.00) lies in their technical capability regarding image resolution. While both are monochrome cathode-ray tubes within the specified size parameters, the sibling category is reserved for those explicitly designed for high-definition video signals, which typically require advanced electron beam control and phosphors to achieve greater detail and clarity. This category, conversely, covers tubes intended for standard definition broadcasts or applications where the highest resolution is not a critical factor.

As this is a leaf node in the HTS classification, there are no further subdivisions under this specific code. Therefore, classification within 8540.12.10.00 relies solely on confirming the monochrome nature of the cathode-ray tube, its intended use as a television picture tube or video monitor tube, and the precise measurement of its faceplate's straight-line dimension falling within the 29 cm to 42 cm range. This ensures accurate tariff application for monochrome CRT displays meeting these specific physical criteria.
