4805.91.10.10 - Folding carton board

This HTS code, 4805.91.10.10, specifically classifies "folding carton board" that falls under the broader category of other uncoated paper and paperboard. This designation is for multi-ply paper and paperboard, as well as bibulous and wrapping paper, weighing 150 g/m² or less. The key characteristic here is its suitability for conversion into folding cartons, implying a certain stiffness, foldability, and surface appropriate for printing and converting processes typical of packaging.

Distinguishing this subcategory from its sibling, 4805.91.10.90 ("Other"), is crucial. While both fall under the "multi-ply paper and paperboard; bibulous and wrapping paper" heading, 4805.91.10.10 is narrowly defined for folding carton board. The sibling category would encompass other multi-ply papers and paperboards within the same weight bracket that are not specifically intended for folding carton production, such as certain types of wrapping papers or bibulous papers not designed for carton manufacturing.

As a leaf node, 4805.91.10.10 has no further subcategories. Therefore, the classification hinges entirely on the accurate identification of the material as folding carton board, its uncoated nature, its construction as multi-ply paper or paperboard, and its weight not exceeding 150 g/m². The intended end-use in producing folding cartons is the primary determinant for this specific classification.
