Last updated: July 2026 dataChains of iron or steel not elsewhere specified — covering non-welded link constructions outside the stud-link and skid-chain categories — are subdivided in the US schedule by link shape and diameter: round links not over 8 mm (7315891000), round links over 8 mm (7315893000), and non-round link configurations (7315895000). China is the dominant supplier, with Malaysia, Germany, and Italy also present in the import mix. The breadth of this residual heading means classification disputes often hinge on whether a chain's links are truly round in cross-section and whether the construction method qualifies as welded.

Chains classified here include those with non-welded link construction — such as twisted, stamped, or interlocked links — that do not qualify as stud link, skid chain, or welded link chain. Decorative chain, certain safety chains, and specialty agricultural or logging chains often land in this residual heading. The key classification exercise is ruling out the more specific subheadings before defaulting to NESOI.
The US tariff lines under 7315.89 distinguish between chains with round wire links and those with non-round links (e.g., oval, flat, or stamped profiles). A chain with oval or flat-bar links falls under 7315895000 rather than the round-link lines, and the diameter breakpoint (8 mm) applies only to round-link variants. Misidentifying link geometry is a common source of classification errors on entry.
