4802.54 - Weighing less than 40 g/m²:

HTS code 4802.54 specifically classifies uncoated paper and paperboard, used for writing, printing, or other graphic purposes, that weighs less than 40 grams per square meter (g/m²). This category encompasses a range of lightweight papers and paperboards that are not manufactured using predominantly mechanical or chemi-mechanical pulping processes, nor do they contain more than 10 percent by weight of such fibers. These characteristics define its niche within the broader group of other paper and paperboard.

Distinction from its sibling categories is primarily based on weight and form. Unlike 4802.55, 4802.56, 4802.57, and 4802.58, which all cover papers weighing 40 g/m² or more, 4802.54 is exclusively for materials weighing *less* than this threshold. The sibling categories also further differentiate based on specific weight ranges and whether the material is presented in rolls or sheets of particular dimensions.

This category is further divided into two subcategories, offering more granular classification. The first subcategory applies to paper and paperboard presented in strips or rolls exceeding 15 cm in width, or in rectangular or square sheets where both dimensions (in the unfolded state) are greater than 15 cm and at least one side exceeds 36 cm. The second subcategory, "Other," captures qualifying papers and paperboards that do not meet the specific dimensional criteria of the first subcategory, ensuring comprehensive coverage of lightweight graphic papers.
