Product classification
HS code for Industrial chain: 7315.89
Chain, n.e.c. in heading no. 7315, of iron or steel.
Classification of industrial chain under HS 7315.89
Industrial chains made of iron or steel are classified under HS code 7315.89. This classification is part of Chapter 73, which covers articles of iron or steel. Heading 7315 specifically addresses chain and parts thereof, of iron or steel. The subheading 7315.89 is a residual category for chains that do not meet the definitions of articulated link chain (such as roller or silent chains) or skid chain. These are typically welded link chains or other non-articulated designs used for heavy-duty industrial applications like hauling, mooring, or lifting. The classification is determined by the material (iron or steel) and the structural design of the links. If the chain links are joined in a way that does not involve pins and rollers (articulation), and it is not a specialized skid chain for tires, it falls under this 'other' category. This code is essential for identifying bulk industrial chain used in construction, maritime, and manufacturing sectors.

Codes often confused with 7315.89
Common mistake. A frequent error is classifying industrial chain under HS code 7315.11, which is specifically for articulated link roller chains (like those used on bicycles or conveyors). Another misclassification occurs with HS code 7312, which covers stranded wire, ropes, and cables; while used for similar purposes, chains are distinct due to their linked construction. Furthermore, if a chain is part of a specific machine, some importers attempt to classify it under Chapter 84 (e.g., 8431 for crane parts), but Note 2 to Section XV generally requires that chains of base metal be classified in their own headings regardless of their use as machine parts.
Top exporters and importers of HS 731589 (the code used for industrial chain), 2025
In 2025, the largest exporter of HS 731589 (the code used for industrial chain) in UN Comtrade data was China, with 35% of world exports; the largest importer in UN Comtrade data was Japan, with 25% of world imports.

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).
