8440.90.00.00 - Parts

HTS Code 8440.90.00.00 specifically covers "Parts" of the bookbinding machinery classified under heading 8440. This category encompasses all components, subassemblies, and accessories that are designed to be integrated into or used with bookbinding machinery, such as book-sewing machines. Examples include specific gears, rollers, cutting blades, motors, frames, or control panels that are identifiable as parts of such equipment and are not considered finished machines themselves.

This "Parts" category is distinguished from its sibling, 8440.10.00.00, which covers the complete "Machinery" for bookbinding. While heading 8440.10.00.00 classifies the assembled and functional bookbinding machines, 8440.90.00.00 is reserved solely for the individual components and pieces that constitute these machines. The classification of an item as a part hinges on its specific design and intended use in conjunction with a bookbinding machine.

As this is a leaf node, there are no further subcategories within 8440.90.00.00. Therefore, all components and spare parts for bookbinding machinery, as described above, fall directly under this classification. The key criterion for classification here is that the item is not a complete machine but rather an integral element thereof, intended for repair, replacement, or the construction of bookbinding machinery under heading 8440.
