Product classification
HS code for Gear pump: 8413.60
Pumps, rotary positive displacement pumps, n.e.c. in heading no. 8413, for liquids.
Classification of gear pump under HS 8413.60
The classification of gear pumps under HS code 8413.60 is determined by the General Rules of Interpretation (GRI), specifically GRI 1 and 6. Heading 8413 covers pumps for liquids, and subheading 8413.60 specifically addresses rotary positive displacement pumps. A gear pump operates by using the meshing of gears to pump fluid by displacement. As the gears rotate, they separate on the intake side of the pump, creating a void and suction which is filled by fluid. The fluid is then carried by the gears to the discharge side of the pump, where the meshing of the gears displaces the fluid. Because this mechanism is inherently rotary and relies on positive displacement rather than centrifugal force, it falls squarely within this classification. This code is used for pumps that are not specifically designed for internal combustion engines and are not centrifugal pumps. The classification remains consistent regardless of whether the pump is an external gear pump, where two identical gears mesh with each other, or an internal gear pump, which uses a rotor and an idler gear. The material of construction, whether cast iron, stainless steel, or specialized alloys, does not typically change the primary heading, provided the device remains a rotary positive displacement pump for liquids.

Codes often confused with 8413.60
Common mistake. Gear pumps are frequently misclassified under HS code 8413.30, which is reserved for fuel, lubricating, or cooling medium pumps for internal combustion engines. If the pump is integrated into an engine system, 8413.30 is correct; however, general-purpose industrial gear pumps must stay in 8413.60. Another common error is using 8413.70, which is for centrifugal pumps; these operate on a completely different physical principle (velocity rather than displacement).
Top exporters and importers of HS 841360 (the code used for gear pump), 2025
In 2025, the largest exporter of HS 841360 (the code used for gear pump) in UN Comtrade data was China, with 19% of world exports; the largest importer in UN Comtrade data was the United States, with 17% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 841360, not only gear pump.

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).
