4810.13 - In rolls:

HTS Code 4810.13 specifically classifies paper and paperboard designed for writing, printing, or other graphic applications, which has been coated on one or both sides with kaolin (China clay) or other inorganic substances. This coating is the primary characteristic, with no other functional coatings present, though surface coloring, decoration, or printing is permitted. The crucial defining element for this subcategory is that the product is presented in rolls.

This category is distinguished from its siblings by its form of presentation. HTS 4810.14 covers similar coated papers and paperboards, but these are presented in sheets where neither dimension exceeds 435 mm by 297 mm. HTS 4810.19 encompasses all other coated papers and paperboards within the broader scope of 4810.1, which do not fit the specific dimensions of 4810.14 or the roll format of 4810.13. Therefore, the "in rolls" criterion is paramount for classification under 4810.13.

The subcategories within 4810.13 further refine the classification based on the width of the paper or paperboard. Goods are categorized as either "Of a width exceeding 15 cm" or "Other," indicating that the physical dimensions continue to be a key factor in distinguishing specific types of coated graphic papers presented in roll form. This allows for more granular tariff treatment based on the practical specifications of the commodity.
