8540.11.10.30 - Not exceeding 39 cm

This HTS classification, 8540.11.10.30, specifically covers color cathode-ray television picture tubes, including those used in video monitors, that are designed for non-high definition and non-projection applications. The defining characteristic of this category is the physical size of the tube's video display diagonal, which must not exceed 39 centimeters. These are the traditional CRT tubes that were prevalent in televisions and computer monitors before the widespread adoption of flat-panel display technologies.

The critical distinguishing factor for this subcategory lies in its size limitation. It is differentiated from its sibling categories by the specific range of its video display diagonal. While 8540.11.10.30 covers tubes with diagonals up to and including 39 cm, sibling categories classify tubes with larger diagonals, such as those exceeding 39 cm but not exceeding 45 cm (8540.11.10.40), and so on, up to tubes exceeding 63 cm. This granular division ensures precise classification based on the physical dimensions of the cathode-ray tube.

As this HTS code represents a leaf node, there are no further subcategories to introduce. Classification within this specific code is determined solely by the criteria of being a color cathode-ray television picture tube, non-high definition, non-projection, and having a video display diagonal not exceeding 39 cm. Importers and exporters should ensure that their goods precisely meet all these specifications to maintain correct classification.
