4805.92.40 - Other

This HTS category, 4805.92.40, encompasses "Other" paper and paperboard that falls within the broader classification of uncoated paper and paperboard, not further processed than specified in note 3 to Chapter 48. Specifically, these are products that weigh more than 150 g/m² but less than 225 g/m². This designation captures a range of paper and paperboard not otherwise specified within the 4805.92 heading.

At this level, it is crucial to distinguish this category from its sibling, 4805.92.20.00, which is specifically for "Pressboard." While both fall under the broader "Other" designation in this weight range, pressboard implies a product engineered for its mechanical strength and density, often used in electrical insulation or as a rigid structural material. This category, 4805.92.40, covers a more general assortment of paper and paperboard that does not meet the specific technical requirements or intended uses of pressboard.

This classification further subdivides into more specific uses and types of paper and paperboard. The subcategories reflect these distinctions: 4805.92.40.10 for Folding carton board, used in the creation of boxes and packaging; 4805.92.40.20 for Construction paper, typically employed in building and crafts; 4805.92.40.30 for Linerboard containing a specific percentage of chemical sulfate wood pulp, crucial in corrugated board manufacturing; and 4805.92.40.40 for "Other" items that do not fit the preceding subcategories but still meet the general weight and uncoated criteria of the parent.
