4810.13.20.90 - Other

This HTS classification, 4810.13.20.90, pertains to paper and paperboard that are coated on both sides with kaolin or other inorganic substances, with or without a binder. Crucially, these materials must not have any other type of coating. The paper or paperboard falls under this specific code when it is intended for writing, printing, or other graphic purposes and does not contain more than 10% of fibers obtained through mechanical or chemi-mechanical processes. Furthermore, the paper is in rolls and has a width exceeding 15 cm, while its weight is greater than 150 g/m².

The distinction between this category and its sibling, 4810.13.20.10 ("Coated on one side only"), is the number of coated surfaces. This code specifically covers paper and paperboard coated on both sides with inorganic substances, whereas the sibling code addresses materials coated only on a single side. This difference in coating application is a key differentiator for accurate classification.

As a leaf node within the HTS structure, this classification does not have further subcategories. Therefore, classification within 4810.13.20.90 is determined by the presence of a double inorganic coating, the intended use for graphic purposes, the fiber composition limits, the roll format with a width over 15 cm, and the weight exceeding 150 g/m². Examples include high-quality art paper or specialized printing papers that meet all these technical specifications.
