4810.14.20 - Weighing more than 150 g/m²

This HTS category, 4810.14.20, specifically classifies paper and paperboard designed for writing, printing, or other graphic purposes. These papers are coated on one or both sides with kaolin or other inorganic substances, potentially with a binder, but without any other coating. The defining characteristic of this subcategory is its weight, which is *more than 150 grams per square meter (g/m²)*. This heavy weight indicates a more substantial and often thicker grade of paper compared to lighter varieties.

Crucially, this category is distinguished from its sibling category, which covers paper and paperboard weighing *not more than 150 g/m²*. Therefore, the primary differentiator is the grammage. Furthermore, this paper must be in sheets with one side exceeding 360 mm and the other side exceeding 150 mm in the unfolded state, and it must not contain fibers obtained by mechanical or chemo-mechanical processes, or contain no more than 10 percent of such fibers by weight.

Within this classification, further distinctions are made based on the coating application. Subcategories exist for paper and paperboard that are *coated on one side only* (4810.14.20.10) and *other* types of coating application (4810.14.20.90), allowing for more precise tariff assignment based on the specific manufacturing process and appearance of the coated paper.
