HS Code 8431.39 – Machinery; parts of the machinery of heading no. 8428, (other than lifts, skip hoists or escalators)
HS code 8431.39 is the 6-digit subheading for machinery, parts of the machinery of heading no. 8428, (other than lifts, skip hoists or escalators). It is used for conveyor belts, crane hooks, trolley assemblies for overhead cranes, conveyor rollers and gearboxes for conveying machinery.
What HS 8431.39 covers
This HS code encompasses parts for a broad range of conveying, hoisting, and handling machinery classified under heading 8428, excluding parts for lifts, skip hoists, and escalators (which fall under 8431.31). This includes components for conveyors, overhead travelling cranes, gantry cranes, mobile lifting frames, and other specialized handling equipment used across various industries. The trade in these parts is essential for maintaining the operational efficiency of logistics, manufacturing, mining, and port operations worldwide. Importers are typically industrial facilities, port authorities, and equipment service companies that rely on these components for continuous operation. Exporters are often OEMs or specialized component manufacturers, providing durable and reliable parts for heavy-duty applications, emphasizing robust construction and compatibility.

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).
