4802.58.20.80 - Other

This classification, HTS Code 4802.58.20.80, encompasses "Other" uncoated paper and paperboard that meets the criteria of heading 4802. Specifically, it applies to paper and paperboard weighing over 150 g/m², presented in strips or rolls exceeding 15 cm in width, or in rectangular sheets where one dimension is over 36 cm and the other is over 15 cm. Crucially, this category covers materials not derived from mechanical or chemi-mechanical pulping processes, or where such fibers constitute 10 percent or less of the total fiber content. This residual category is for paper and paperboard that, while fitting the general parameters of uncoated writing, printing, or graphic papers, do not fall under more specific descriptions.

To distinguish this category from its siblings, note that 4802.58.20.20 is specifically for drawing paper, and 4802.58.20.40 is for bristols. Those categories have distinct intended uses or structural characteristics that set them apart. This "Other" classification is therefore for items that do not qualify for those more precise designations, such as certain types of cardstock or specialty paperboards used for graphic purposes but not falling into the aforementioned categories.

As this is a leaf node in the HTS classification, there are no further subcategories. Therefore, the key to correctly classifying items here lies in meticulously ensuring they meet all preceding criteria within heading 4802.58.20 and then confirming they do not fit any of the more specific sibling classifications based on their intended application or particular attributes.
