Parts of Iron or Steel Chain (NESOI)

Parts of chain under 7315.90 are components designed specifically for use with chain — such as master links, repair links, and coupling links — that are not themselves complete chain lengths. General-purpose fasteners, hooks, or shackles that can be used independently are typically classified elsewhere in Chapter 73 (e.g., under 7315.89 or 7316). The key test is whether the article's primary design function is to join or repair chain links.

Section 232 measures on steel articles apply broadly by product category and origin, and chain parts of iron or steel generally fall within scope. However, certain countries have negotiated exemptions, quotas, or alternative arrangements. Importers should verify the current Section 232 status for the specific country of origin with a licensed customs broker, as the landscape of exemptions has changed over time.
