7315.11.00.60 - Other

This HTS category, "Other," under roller chain, encompasses roller chain and its parts that do not fit into the preceding more specific subheadings. It serves as a residual category for articulated link roller chains that have a pitch of over 50 mm, or those with a pitch of 50 mm or less but do not contain more than 3 parts per pitch. The classification hinges on the physical dimensions of the chain, specifically its pitch, and the complexity of its construction as measured by the number of parts per pitch.

This category is distinct from its sibling, "Of not over 50 mm pitch and containing more than 3 parts per pitch," which specifically targets roller chains with a smaller pitch and a higher degree of component complexity. Therefore, this "Other" category captures a broader range of roller chains, including those with larger pitches that are commonly used in heavier-duty industrial applications, as well as simpler roller chain designs within the 50 mm pitch threshold.

As this is a leaf node in the HTS structure, there are no further subcategories. The classification of goods under 7315.11.00.60 is definitive once it is determined that they are roller chains and do not meet the criteria for the more specific preceding subheadings. Importers and exporters should carefully measure the pitch and count the number of parts per pitch to accurately determine if their roller chain falls within this residual classification.
