8440.10.00.00 - Machinery

This HTS category, 8440.10.00.00, specifically encompasses bookbinding machinery. This includes a wide array of equipment designed for the assembly and finishing of books. Examples of such machinery include automatic case makers, folding machines, creasing machines, trimming machines, and collating machines that prepare pages for binding. The primary function of these machines is to perform various operations in the process of binding multiple sheets of paper together into a book or booklet.

It is important to distinguish this category from its sibling, 8440.90.00.00, which covers only the "Parts" of bookbinding machinery. While this category focuses on the complete machines designed for bookbinding operations, the sibling category is exclusively for individual components, replacement parts, or accessories that are not themselves functional bookbinding machines. For example, a new motor or a set of cutting blades for a book trimmer would fall under 8440.90.00.00, whereas the entire book trimmer unit would be classified here.

As a leaf node within the HTS structure, there are no further subcategories under 8440.10.00.00. Therefore, the classification of any bookbinding machinery will directly fall into this heading, provided it meets the general description and is not merely a part thereof. The scope of this category is thus limited to the finished, operational machines used in the bookbinding industry.
