4810.13.70.40 - Other

This HTS category, 4810.13.70.40, classifies "Other" paper and paperboard that falls within the broader description of paper coated with kaolin or other inorganic substances. Specifically, it pertains to paper and paperboard of a kind used for writing, printing, or other graphic purposes, which does not contain fibers obtained by a mechanical or chemo-mechanical process, or where such fibers constitute no more than 10 percent by weight of the total fiber content. The paper is supplied in rolls and has undergone the specified inorganic coating.

This category is distinguished from its sibling, 4810.13.70.20, which specifically covers paper and paperboard containing by weight 25 percent or more of cotton fiber. Therefore, 4810.13.70.40 encompasses all other qualifying papers and paperboards meeting the coating and fiber content requirements, excluding those with a substantial cotton fiber composition. The "Other" designation at this level signifies that this is the residual category for eligible paper and paperboard that does not fit into more specific sub-classifications at this hierarchical level.

As this is a leaf node within the HTS, there are no further subcategories. Classification within 4810.13.70.40 is determined by meeting all the preceding criteria: being coated with kaolin or other inorganic substances (without other coatings), being suitable for writing, printing, or graphic purposes, having limited mechanical or chemo-mechanical fiber content, and being supplied in rolls. The absence of specific subtypes means that any product meeting these core requirements, but not falling into the distinct cotton fiber sibling, will be classified here.
