8540.12.70.00 - High definition

This classification pertains to monochrome cathode-ray television picture tubes, specifically those designed for high-definition displays. These tubes are characterized by their ability to render images with a significantly greater number of pixels and detail compared to standard definition tubes. They are integral components for older television sets and certain display monitors where the cathode-ray tube technology is still employed for high-resolution imaging.

The key differentiator for this category, 8540.12.70.00, lies in its designation as "High definition." This distinguishes it from its sibling category, 8540.12.50, which covers monochrome cathode-ray television picture tubes that are not high definition, meaning they are designed for standard definition or lower resolution displays. The distinction is crucial for determining applicable tariff rates and import regulations, reflecting differences in the technological sophistication and performance capabilities of these display components.

As this classification represents a leaf node within the HTS structure, there are no further subcategories. Therefore, the classification ends with the specific identification of high-definition monochrome cathode-ray television picture tubes. When encountering these goods, the primary classification criteria will be the tube's design and technical specifications that confirm its high-definition capability, along with its intended use in monochrome television or video monitor applications.
