4802.57.40 - Other

This category, HTS 4802.57.40, encompasses "Other" paper and paperboard that meets the general specifications of heading 4802.57: it is uncoated, not derived primarily from mechanical or chemi-mechanical pulping processes (containing 10% or less of such fibers), and weighs between 40 and 150 grams per square meter. Unlike its siblings, this residual "Other" category is not specifically designated for writing and cover paper (4802.57.10), drawing paper (4802.57.20), or India and bible paper (4802.57.30).

Therefore, this classification serves as a catch-all for papers and paperboards within the defined weight range and fiber composition that do not fit into the more specific sub-classifications. Its inclusion as an "Other" category allows for the proper classification of various paper products that meet the broader criteria but lack the distinct characteristics or intended uses of the enumerated sibling categories.

Within this residual category, further distinctions are made based on precise dimensions. Subcategory 4802.57.40.40 specifically identifies paper and paperboard with one unfolded side measuring 965 mm and the other 635 mm. All other papers and paperboards that fall under the general "Other" designation of 4802.57 and do not meet the specific dimensional criteria of 4802.57.40.40 are then classified under the residual subcategory 4802.57.40.85.
