HS code for Roller chain: 7315.11
Chain, articulated link, roller, of iron or steel.
Classification of roller chain under HS 7315.11
Roller chains are classified under HS code 7315.11. This code falls within Chapter 73, which covers articles of iron or steel. Heading 7315 specifically addresses chains and parts thereof made of iron or steel. The subheading 7315.11 is designated for articulated link chains of the roller type. These chains consist of a series of short cylindrical rollers held together by side links and are driven by sprockets. They are widely used in domestic, industrial, and agricultural machinery for the transmission of power or as a conveyor element. The classification is determined by the material (iron or steel) and the specific mechanical design (articulated links with rollers), distinguishing them from leaf chains or welded link chains.

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).
