7315.11.00.45 - Other

This HTS category, 7315.11.00.45, encompasses roller chains of iron or steel that are not over 50 mm in pitch and contain more than three parts per pitch. These chains are characterized by their articulated link construction, where individual components like rollers, pins, and plates are assembled to form a continuous loop. The specified pitch dimension and number of parts per pitch are critical criteria for inclusion in this subcategory, indicating a specific design and complexity often associated with mechanical power transmission in industrial machinery, agricultural equipment, and certain types of vehicles.

This classification is distinct from its sibling category, 7315.11.00.10, which specifically covers bicycle chains. While both are roller chains, the "Other" designation here indicates that these chains are not intended for use in bicycles. The physical dimensions, load-bearing capacities, and intended applications for chains classified under 7315.11.00.45 are generally more robust and suited for heavier-duty industrial operations compared to the lighter-duty requirements of bicycle chains.

As this is a leaf node in the HTS, there are no further subcategories. Therefore, classification within this code relies solely on meeting the defined criteria of being a roller chain of iron or steel with a pitch not exceeding 50 mm and containing more than three parts per pitch, excluding those specifically classified as bicycle chains. The focus remains on the precise physical attributes and construction to ensure accurate tariff application.
