7315.12.00 - Other chain

This HTS category, 7315.12.00, encompasses "Other chain" made of iron or steel, specifically falling under articulated link chains. This classification is designed for articulated link chains that are not of the roller chain type and are not considered parts of chains. The defining characteristic is their construction from interconnected links, forming a flexible, continuous length used for transmitting power, lifting, pulling, or securing.

To distinguish this category from its siblings, it's important to note that 7315.11.00 specifically covers roller chains, which feature cylindrical rollers between the inner and outer plates of the links to reduce friction and wear, typically used in mechanical power transmission. Category 7315.19.00.00, conversely, is reserved for individual parts of articulated link chains, rather than complete chains.

Within this category, further subdivisions exist to refine classification based on specific physical attributes. The subcategory 7315.12.00.20 covers chains with a pitch not exceeding 50 mm that contain more than three parts per pitch. The remaining "Other" classification within this node is for articulated link chains that do not meet the specific criteria of the preceding subcategory, ensuring a comprehensive coverage of all non-roller, articulated link chains that are not solely parts.
