8305.10.00.10 - Ring binder mechanisms

This HTS category, 8305.10.00.10, specifically classifies ring binder mechanisms. These are the metal components designed to hold pages within loose-leaf binders and files. They typically consist of rings, levers, and other interconnected parts that allow for the insertion and removal of paper. The primary function is to facilitate the organization and retention of documents in a binder format.

Within the broader heading of "Fittings for looseleaf binders or files," this subcategory is distinguished from its sibling, 8305.10.00.50, which covers "Other" fittings. While this node is precisely for the ring binder mechanisms themselves, the sibling category would encompass other types of fittings used in loose-leaf systems that are not ring mechanisms, such as specialized clamps or unique fastening devices.

As this is a leaf node in the HTS database, there are no further subcategories. Therefore, the classification here is definitive for ring binder mechanisms of base metal. Examples include the D-ring, O-ring, and lever-arch mechanisms commonly found in office binders, folders, and presentation books. The material being of base metal is a critical defining characteristic for inclusion in this category.
