U.S. imports of articulated link chain (non-roller) of iron or steel (HS 731512) totaled $9.4M in April 2026, traded with 32 countries.
Last updated: April 2026 dataArticulated link chain that lacks the cylindrical roller of a roller chain — including welded steel chain, cast chain, and combination chain — serves lifting, towing, mooring, and conveyor applications where roller engagement with a sprocket is not required. The US schedule breaks out four 10-digit lines: chains with pitch not over 50 mm and more than three parts per pitch (7315120020), welded steel articulated chain (7315120040), cast and combination chain (7315120060), and a residual NESOI line (7315120080). Germany leads supply, reflecting European strength in heavy-duty lifting and marine chain; China is the second-largest source and carries Section 301 tariff exposure. Grade markings and proof-load certifications are critical commercial and safety documentation for lifting-grade chain.

While CBP does not mandate specific safety certifications at the border, OSHA and ASME B30.9 standards govern the use of lifting chain in US workplaces, and buyers typically require proof-load test certificates, grade markings (e.g., Grade 80 or Grade 100), and manufacturer traceability documentation. Importers should ensure these documents accompany the shipment to satisfy downstream customer requirements and avoid liability exposure.
Combination chain incorporates both cast and wrought (or welded) links within the same chain assembly, distinguishing it from purely welded or purely cast constructions. This hybrid construction is common in certain conveyor and drag-chain applications. If the chain is entirely welded steel, it belongs under 7315120040; if entirely cast, it also falls under 7315120060 as a cast chain. When the construction is mixed, the combination chain line applies.
