4811.90.90 - Other

This HTS category, 4811.90.90, broadly covers "Other" paper, paperboard, cellulose wadding, and webs of cellulose fibers that have been coated, impregnated, covered, surface-colored, surface-decorated, or printed. These articles are presented in rolls or rectangular sheets. Crucially, this heading applies to goods not specifically classified under headings 4803, 4809, or 4810, which typically deal with specific types of paper like toilet paper, carbon paper, or coated paper for specific graphic uses.

Within the broader scope of chapter 48, this particular heading (4811) focuses on a wide array of processed cellulosic materials beyond basic paper. The "Other" designation within 4811.90.90 signifies that it captures those products that do not fit into the more specific subheadings of 4811.90, particularly those defined by specific dimensions like strips or rolls exceeding 15 cm in width or rectangular sheets with one side exceeding 36 cm and the other exceeding 15 cm.

The subcategories under 4811.90.90 provide further specificity for classification. For instance, tissue papers with a basis weight not exceeding 29 g/m² in sheets are distinguished, as is direct thermal coated paper used in specific printing applications. Additionally, paper in sheets with precise dimensions for ruled or lined paper represents another distinct group. Finally, the "Other" residual subheading (4811.90.90.80) serves as a catch-all for any processed cellulosic materials meeting the general description of heading 4811 but not otherwise enumerated in its more specific subheadings.
