HS Code 7315.19 – Chain; articulated link parts, of iron or steel
HS code 7315.19 is the 6-digit subheading for chain, articulated link parts, of iron or steel. It is used for roller chain links, conveyor chain links, leaf chain links, anchor chain parts and transmission chain components.
What HS 7315.19 covers
This HS code covers articulated link parts of chain, made from iron or steel, which are essential components for assembling or repairing various types of industrial and mechanical chains. These parts are crucial in sectors requiring robust power transmission, lifting, or conveying systems, such as heavy machinery manufacturing, automotive production, agricultural equipment, and material handling. Importers and exporters typically include specialized component manufacturers, industrial distributors, and maintenance, repair, and overhaul (MRO) suppliers. Key considerations in trade involve the specific link design (e.g., roller, leaf, silent chain links), material grade for strength and wear resistance, and compliance with international standards for dimensions and load capacity. The global demand for these parts is closely tied to industrial output and infrastructure development.

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).
