HS Code for Stud link chain

Stud link chain is classified under HS code 7315.81. This classification is found within Chapter 73, which covers articles of iron or steel. Heading 7315 specifically addresses chains and parts thereof. The subheading 7315.81 is reserved for "stud-link" chain, a specialized type of heavy-duty chain where each link contains a transverse bar, or "stud," across its center. This design is a critical engineering feature that prevents the links from stretching or deforming under extreme tension. It also prevents the chain from kinking or knotting, which is vital for maritime safety. Because the HS system classifies goods based on their physical characteristics and construction, the presence of this stud is the primary factor for its placement in 7315.81. These chains are most commonly used in the shipping industry for anchor cables and offshore mooring systems.

Common Misclassification

The most frequent misclassification is with HS code 7315.82, which covers "other" welded link chains. If a chain is welded but lacks the internal stud, it must be classified under 7315.82, even if it is used for similar maritime purposes. Another common error is using 7315.11, which is reserved for roller chains (like those used on bicycles or industrial machinery). Stud link chains are distinct because they are typically forged and welded link-by-link rather than being assembled from pins and rollers.
