4811.90.30.00 - Impregnated with latex

This classification, HTS Code 4811.90.30.00, specifically covers paper, paperboard, cellulose wadding, and webs of cellulose fibers that have been impregnated with latex. This impregnation process imparts distinct properties to the cellulosic material, such as enhanced water resistance, flexibility, and durability. These characteristics differentiate latex-impregnated articles from other forms of treated paper and paperboard found within heading 4811.

Within the broader category of "Other paper, paperboard, cellulose wadding and webs of cellulose fibers," this subcategory distinguishes itself by the specific treatment of latex impregnation. While other subcategories might cover paper and paperboard that are coated, surface-colored, or decorated, the defining characteristic here is the inherent alteration of the material's structure and properties through the absorption and binding of latex.

As this is a leaf node, there are no further subdivisions. Therefore, the classification hinges directly on the presence of latex impregnation as the primary distinguishing feature of the cellulosic product. Examples falling under this code would include, but are not limited to, latex-impregnated papers used in the manufacturing of industrial goods, specialized packaging, or certain types of technical textiles where the latex provides structural integrity and barrier properties.
