8528.49.80.00 - Black and white or other monochrome

This HTS category specifically encompasses cathode-ray tube (CRT) monitors that display images in black and white or other monochrome formats. These devices are characterized by their reliance on electron beams to illuminate phosphor dots on a screen, producing a single-color image. This designation excludes CRT monitors capable of displaying full-color images.

The distinction between this category and its sibling category, "Color," is fundamental. While both fall under CRT monitors, this classification is strictly for those devices incapable of rendering multiple colors. The underlying technology for monochrome display differs from that used for color reproduction, making this a key differentiator for customs purposes.

As a leaf node within the HTS structure, there are no further subcategories under this specific classification. Therefore, the classification of a CRT monitor under 8528.49.80.00 is definitively determined by its monochrome display capability. This ensures that only devices with the specified visual output are categorized here, simplifying import and export declarations for these particular types of display apparatus.
