Product classification
HS code for Fluid pump: 8413.81
Pumps and liquid elevators, n.e.c. in heading no. 8413.
Classification of fluid pump under HS 8413.81
Fluid pumps are classified under HS code 8413.81, a subheading for pumps for liquids that are not elsewhere classified (n.e.c.) within heading 8413. Heading 8413 covers a wide range of liquid pumps, including reciprocating, rotary, and centrifugal types. Subheading 8413.81 acts as a basket category for specialized pumps that do not fit the specific technical descriptions of the preceding subheadings. The classification is determined by the device's primary function: moving liquids through mechanical action. This includes hydraulic ram pumps and other non-centrifugal, non-rotary designs. It is essential to verify that the pump is intended for liquids; if it were for air or gases, it would fall under heading 8414. The presence of integrated measuring devices or specific industrial applications would also shift the classification to other subheadings within 8413, making 8413.81 the correct choice only when more specific descriptions are not met.

Codes often confused with 8413.81
Common mistake. Fluid pumps are often misclassified under HS code 8413.70, which is the specific code for centrifugal pumps, the most common type of liquid pump. They may also be confused with HS code 8413.11 or 8413.19 if they are fitted with a measuring device (like those at gas stations). Furthermore, if the pump is part of a larger machine and loses its individual identity, it might be classified as a part of that machine, though GRI 1 generally requires pumps to be classified under 8413 regardless of their intended use.
Top exporters and importers of HS 841381 (the code used for fluid pump), 2025
In 2025, the largest exporter of HS 841381 (the code used for fluid pump) in UN Comtrade data was Italy, with 18% of world exports; the largest importer in UN Comtrade data was the United States, with 8.6% 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).
