4901.10.00 - In single sheets, whether or not folded

This HTS category, 4901.10.00, specifically covers printed books, brochures, leaflets, and similar printed matter when presented in single sheets, regardless of whether these sheets are folded. The defining characteristic here is the format of presentation. This encompasses unbound printed materials that have not yet been assembled into a finished book or booklet. Examples include single-sheet posters with significant text, unassembled pages of a book intended for later binding, or folded leaflets that are not yet bound or stapled.

This category distinguishes itself from its sibling, "Other" (which would typically be a higher-level category not detailed here), by its explicit focus on single sheets. The sibling category would encompass printed matter that does not fit the specific criteria of single sheets or other more granular subheadings within Chapter 49. The crucial differentiator for 4901.10.00 lies in the item's state of assembly.

Within this category, two subcategories exist to further refine classification. Subcategory 4901.10.00.20, "Reproduction proofs," is for materials intended for reproduction, such as film negatives or digital files containing layout and text for printing. Subcategory 4901.10.00.40, "Other," captures all remaining printed matter in single sheets that do not qualify as reproduction proofs, ensuring comprehensive coverage of this presentation format.
