8540.12.50.40 - Projection

This HTS category, 8540.12.50.40, specifically covers monochrome cathode-ray television picture tubes, including those used in video monitors, that are classified as "Projection" types. These are distinct from other cathode-ray tubes by their design and intended function, which is to project an image onto a separate screen rather than displaying it directly on the tube face itself. The classification hinges on the specific projection technology employed within the cathode-ray tube.

At this level of the tariff schedule, the distinction between this "Projection" subcategory and its sibling, "Other" (8540.12.50.80), lies in the inherent projection capability. While both are monochrome cathode-ray television picture tubes, the "Other" category would encompass projection tubes that do not fit the specific criteria for this subcategory, or other monochrome cathode-ray tubes not designed for projection purposes, if any exist at this granular level.

As this classification represents a leaf node within the HTS database, there are no further subcategories. Therefore, the primary focus for classification within 8540.12.50.40 is on confirming that the goods are indeed monochrome cathode-ray television picture tubes and possess the specific technical characteristics that define them as "Projection" types, as opposed to direct-view displays. Classification relies on a thorough examination of the product's design and operational principles to confirm its projection functionality.
