What HS 7315.90 covers
This HS code covers parts specifically designed for iron or steel chains, but not complete chains themselves. This includes a wide array of components essential for chain assembly, repair, extension, or connection, such as various types of links, hooks, shackles, and other fittings. These parts are crucial for maintaining the integrity and functionality of chain systems across diverse industries, from heavy lifting and marine applications to industrial machinery and general hardware. Importers typically include chain manufacturers, industrial suppliers, hardware distributors, and maintenance companies that require components for repair or custom assembly. Exporters are often specialized metal fabricators and component manufacturers with expertise in producing high-strength, precision-engineered chain accessories. Key factors in trade involve material compatibility with the chain, specified load ratings, precise dimensions, and adherence to safety standards for seamless integration into existing chain systems.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
