HTS heading 7315 is a broad product category for chains and chain parts made of iron or steel. It can group items such as chain assemblies, links, and certain specialized chain types, with the exact classification depending on the chain’s design, construction, and intended use.
To reach the correct 8-digit HTSUS code, start with the heading and then follow the more detailed subheadings under it. Those subdivisions may distinguish the product by material characteristics, chain type, dimensions, construction, or whether it is a complete chain or a part. Do not assume that every metal item described as a “chain” belongs here; the product’s objective physical features control classification, and unusual or specialized goods may require customs-broker review.
What to check
- Identify the chain’s exact construction, including link shape, welds, rollers, pins, attachments, and whether it is a complete chain or a separate part.
- Confirm the material: document whether it is iron, steel, stainless steel, or another material, and retain supplier specifications or laboratory information when needed.
- Measure and record relevant dimensions, such as link size, wire or bar diameter, pitch, length, and load rating; compare them with the wording of the available subheadings.
- Read every 8-digit option and its legal notes, not just the product description or a search result; check whether the wording matches the chain’s type and physical features.
- Ask a customs broker or seek a formal classification ruling when the chain is specialized, combined with machinery, marketed as a component, or could fit more than one heading.

How to find your code in this category
A heading is a product category. To get the exact duty, narrow from this 4-digit heading to a sub-category (usually by material), then open the 8-digit code that matches your product.
Open any code in the tables below to see its exact duty rate, a duty calculator (enter your shipment value → estimated duty and landed cost), the rate-change history chart, and the country-by-country breakdown (including Section 301/232 add-on duties).
Why you have to click in: a single category can contain products with very different duties. The rate depends on the specific product — its material and construction — and on the country of origin, and those only get pinned down at the 8-digit code level. That is why this page points you to codes instead of showing one rate for the whole category.
