7315.82.10.00 - Not over 10 mm in diameter

This HTS classification, 7315.82.10.00, specifically covers welded link chain made from alloy steel, where the individual links have a diameter of not exceeding 10 mm. This category applies to a variety of applications where smaller, robust chain is required, such as in light-duty rigging, decorative purposes, animal restraints, or as components in machinery and equipment where precise, controlled movement is essential. The defining characteristic for classification within this sub-heading is the material composition (alloy steel) and the precise physical dimension of the chain links.

It is crucial to distinguish this classification from its sibling, 7315.82.30.00, which covers similar welded link chain of alloy steel but with links exceeding 10 mm in diameter. The 10 mm threshold is a critical determinant for proper classification. Therefore, even if the chain is made of alloy steel and is welded, if its link diameter surpasses this specific measurement, it would fall under the sibling category.

As this is a leaf node within the HTS, there are no further subdivisions under 7315.82.10.00. All welded link chain of alloy steel with links not exceeding 10 mm in diameter will be classified here. When classifying, customs officers will verify the material composition to ensure it meets the criteria for "alloy steel" and will measure the diameter of the links to confirm they are 10 mm or less.
