4810.29.70 - Other

HTS Code 4810.29.70 encompasses "Other" paper and paperboard, specifically within the broader category of paper coated with kaolin or other inorganic substances. This classification applies to paper and paperboard that meets the general criteria of Chapter 48, is mechanically or chemimechanically processed to more than 10 percent of its fiber content, and is coated on one or both sides with kaolin or other inorganic substances without any additional coating.

This residual "Other" classification serves to capture paper and paperboard that, while fitting the overarching requirements of subheading 4810.29, does not fall into more specific sub-classifications. It is distinct from the sibling category 4810.29.60.00, which is exclusively reserved for basic paper specifically intended for sensitization in photographic applications. Therefore, 4810.29.70 is for all other types of mechanically processed, inorganic-coated paper and paperboard that are suitable for writing, printing, or other graphic purposes.

Within this "Other" category, further distinctions are made based on the fiber composition. Subcategory 4810.29.70.20 specifically identifies paper and paperboard containing by weight 25 percent or more of cotton fiber. The subsequent "Other" subcategory, also under 4810.29.70, will then cover all remaining paper and paperboard within this classification that does not meet the specific cotton fiber percentage requirement.
