7315.12.00.40 - Welded steel chain

This HTS category, 7315.12.00.40, specifically classifies welded steel chain. This type of chain is constructed by joining metal links through a welding process, creating a continuous, articulated assembly. Such chains are widely used in various industrial applications, including material handling, towing, and general rigging, where strength and durability are paramount. The defining characteristic for classification under this heading is the method of link formation.

This category is distinguished from its sibling, 7315.12.00.60, which covers cast and combination chain. Cast chain is formed by pouring molten metal into molds to create the links, while combination chain typically involves a mix of different link types or manufacturing methods. Unlike these, 7315.12.00.40 is exclusively for chains where each link is formed and joined through welding. The sibling category 7315.12.00.80 acts as a residual category for other articulated link chains not covered by the specific weld, cast, or combination descriptions.

As a leaf node, 7315.12.00.40 does not have further subcategories. Therefore, classification within this code relies on accurately identifying the chain as being constructed from steel and formed through a welding process. Any other methods of link construction, such as casting or a combination of methods, would fall under the sibling headings.
