HS Code for Anchor chain

Anchor chain is classified under HS code 7315.81, which falls within Chapter 73 for articles of iron or steel. Heading 7315 is dedicated to chain and parts thereof, of iron or steel. The specific subheading 7315.81 is reserved for "stud-link" chain. In maritime and heavy industrial applications, a stud-link chain is characterized by a small solid bar (the stud) forged or welded across the width of each link. This design serves two critical purposes: it prevents the link from deforming under extreme tension and ensures the chain does not kink or tangle during deployment or retrieval from a chain locker. Because of this distinct structural feature and its primary use in heavy-duty anchoring for ships and offshore platforms, it is separated from other types of welded or articulated chains. The classification is based on the material (iron or steel) and the specific manufacturing design (stud-link) rather than the final application alone.

Products Included

• Marine stud-link anchor chains
• Offshore mooring stud-link chains
• Galvanized steel stud-link chains
• High-tensile steel anchor chains with studs

Common Misclassification

Anchor chains are often misclassified under 7315.82, which covers other welded-link chains that lack the internal stud. They may also be confused with 7315.89, a general category for other types of chain. In some cases, importers mistakenly look at Chapter 89 (Ships and Boats), but general hardware like chains remains classified by material in Chapter 73.

FAQ

What is the HS code for anchor chain?

The specific HS code for stud-link anchor chain made of iron or steel is 7315.81.

Why is stud-link chain classified differently from regular chain?

Stud-link chain is classified separately because the addition of the stud provides unique mechanical properties and is a standard requirement for large-scale maritime anchoring systems.
