8540.11.30.00 - High definition, having a video display diagonal exceeding 35.56 cm

This HTS category specifically covers color cathode-ray television picture tubes, including those used in video monitors, that are classified as "high definition" and possess a video display diagonal measuring greater than 35.56 centimeters. The "high definition" designation generally implies a higher resolution than standard definition, leading to a sharper and more detailed image. The explicit measurement of the display diagonal is a key distinguishing factor for classification within this sub-heading.

The primary differentiator for this category, compared to its siblings, lies in the combined criteria of being high definition and having a display diagonal exceeding 35.56 cm. Sibling categories at this level distinguish themselves based on whether they are high definition or not, and whether the display diagonal is above or below the 35.56 cm threshold, or fall into an "other" residual category. For instance, a non-high definition tube with the same diagonal measurement would be classified elsewhere, as would a high definition tube with a smaller diagonal.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, the classification into 8540.11.30.00 is the final determination for eligible goods. Classification professionals should ensure that both the "high definition" technical specification and the precise measurement of the video display diagonal are thoroughly verified to ensure accurate duty assessment and compliance.
