Product classification
HS code for Piston pump: 8413.50
Pumps, reciprocating positive displacement pumps, n.e.c. in heading no. 8413, for liquids.
Classification of piston pump under HS 8413.50
Piston pumps are classified under HS code 8413.50, which covers reciprocating positive displacement pumps for liquids. This classification is found in Chapter 84, which deals with nuclear reactors, boilers, machinery, and mechanical appliances. The determination for this code is based on the mechanical principle of the pump: it must be a positive displacement pump that utilizes a reciprocating motion (such as a piston or plunger) to move fluid. Heading 8413 includes all pumps for liquids, and the subheadings are organized by the type of pump mechanism. Subheading 8413.50 is the specific category for reciprocating pumps that are not otherwise specified (n.e.c.) in more specific subheadings like 8413.11 (pumps with measuring devices). The classification applies regardless of the power source (manual, electric, or fuel-driven) as long as the internal mechanism is reciprocating.

Codes often confused with 8413.50
Common mistake. Piston pumps are frequently confused with HS code 8413.60, which covers rotary positive displacement pumps (like gear or vane pumps). The key difference is the motion: reciprocating (up and down/back and forth) versus rotary (circular). Another common misclassification is HS code 8414.80, which covers air pumps and compressors. It is vital to distinguish if the pump is designed for liquids (8413) or gases (8414). Additionally, if the piston pump is part of a specific machine and is not identifiable as a standalone pump, it might be classified as a part of that machine, though heading 8413 generally takes precedence for pumps.
Top exporters and importers of HS 841350 (the code used for piston pump), 2025
In 2025, the largest exporter of HS 841350 (the code used for piston pump) in UN Comtrade data was Germany, with 23% of world exports; the largest importer in UN Comtrade data was the United States, with 22% 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 841350, not only piston 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).

Questions about piston pump
What is the HS code for Piston pump?
The HS code for Piston pump is 841350 (Pumps; reciprocating positive displacement pumps, n.e.c. in heading no. 8413, for liquids). The HS code for reciprocating positive displacement piston pumps for liquids is 8413.50.
How do I classify Piston pump for customs?
Piston pump is classified under HS code 841350 — Pumps; reciprocating positive displacement pumps, n.e.c. in heading no. 8413, for liquids. This is a 6-digit subheading level code.
Is a piston pump for air classified under 8413.50?
No, HS code 8413.50 is strictly for pumps for liquids. A piston pump designed for air or gas is classified as a compressor or air pump under heading 8414.
Which countries are the top exporters of piston pump (HS 841350)?
In 2025, the top exporters of HS 841350 (the code used for piston pump) in UN Comtrade data were Germany ($2.5B, 23% of world exports), the United States ($2.0B) and China ($1.4B). World exports came to about $10.8B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
