4802.57.10.40 - With one side equal to 965 mm and the other side equal to 635 mm in the unfolded state

This HTS category, 4802.57.10.40, specifically classifies uncoated paper and paperboard used for writing, printing, and other graphic purposes. The defining characteristic of this subcategory is its specific dimensions when unfolded: one side measuring 965 mm and the other 635 mm. This precise sizing is a crucial factor for determining its classification within the broader group of other paper and paperboard not derived from mechanical or chemi-mechanical pulping processes, and weighing between 40 and 150 grams per square meter.

This particular classification is distinguished from its sibling category, 4802.57.10.85 ("Other"), by the precise physical dimensions stated. While both fall under the umbrella of "Writing and cover paper" and share similar weight and fiber composition characteristics, the explicit measurement requirement for 4802.57.10.40 makes it a distinct entry. This ensures that paper meeting these exact specifications is correctly identified and separated for customs purposes.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, the focus for classification under 4802.57.10.40 lies solely on the product meeting the description of uncoated paper or paperboard, intended for graphic applications, with the specified unfolded dimensions of 965 mm by 635 mm, and adhering to the weight and fiber content criteria of its parent categories.
