4804.52.00.50 - Other

This HTS classification, 4804.52.00.50, encompasses "Other" uncoated kraft paper and paperboard that meets stringent criteria. Specifically, it applies to kraft paper and paperboard weighing 225 g/m² or more, which has been bleached uniformly throughout the mass. A key defining characteristic is that more than 95 percent by weight of its total fiber content must consist of wood fibers obtained through a chemical process. This category acts as a residual for bleached, chemically processed kraft paper and paperboard meeting these weight and fiber requirements when it does not fall under other more specific subheadings.

Distinguishing this category from its sibling, 4804.52.00.40, is crucial. The sibling category is specifically designated for "Base stock for packaging," implying a particular end-use application. In contrast, 4804.52.00.50 is for other applications that do not fit the "base stock for packaging" description. Therefore, if a bleached, chemically processed kraft paper or paperboard meeting the weight and fiber content requirements is not intended for use as a base stock for packaging, it would likely be classified under this "Other" designation.

As this node is a leaf node, there are no further subcategories. Classification decisions within this heading are therefore dependent on accurately fulfilling all the preceding criteria: being uncoated kraft paper or paperboard, weighing 225 g/m² or more, being bleached uniformly throughout the mass, and having a wood fiber content exceeding 95% derived from a chemical process, while not being specifically designated as base stock for packaging. This ensures a precise classification for a broad range of specialized kraft paper and paperboard products.
