Product classification
HS code for Water pump: 8413.81
Pumps and liquid elevators, n.e.c. in heading no. 8413.
Classification of water pump under HS 8413.81
Water pumps that do not fit into the more specific subheadings of heading 8413 are classified under HS code 8413.81. Heading 8413 covers pumps for liquids, whether or not fitted with a measuring device, and liquid elevators. While many water pumps are classified as centrifugal pumps (8413.70) or reciprocating positive displacement pumps (8413.50), the 8413.81 code serves as a residual category for "other pumps." This often includes specific types of pumps like hydraulic ram pumps, certain types of rotary pumps not specified elsewhere, or specialized liquid elevators. Classification under 8413.81 is determined by excluding the pump from the more specific descriptions in subheadings 8413.11 through 8413.70. It is essential to review the technical specifications of the pump to ensure it does not meet the criteria for centrifugal or displacement pumps before defaulting to this residual code. This classification follows GIR 1 and GIR 6.

Codes often confused with 8413.81
Common mistake. The most frequent misclassification is using 8413.81 for standard centrifugal water pumps, which should actually be under 8413.70. Centrifugal pumps are the most common type of water pump, and 8413.70 is a very broad category. Another common error is misclassifying pumps designed for internal combustion engines (like automotive water pumps) under 8413.81, when they should be under 8413.30. Additionally, vacuum pumps are classified in 8414 and should not be confused with liquid pumps.
Top exporters and importers of HS 841381 (the code used for water pump), 2025
In 2025, the largest exporter of HS 841381 (the code used for water 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).
