HS Code for Water Pump
Water pumps are classified under HTS heading 8413, which covers pumps for liquids. Most stand-alone water pumps are centrifugal and point toward 8413.70, while non-centrifugal pumps point toward 8413.81 — both are generally duty-free. Pumps that are part of an internal combustion engine system, including engine coolant (water) pumps and fuel pumps, point toward 8413.30 at around 2.5%. Pump parts point toward 8413.91. The right code depends mainly on whether the pump is a stand-alone centrifugal pump or an engine-mounted pump.
| HTS Code | Description | Duty Rate |
|---|---|---|
| 8413.70.20.90 | Other centrifugal pumps — other Centrifugal water pumps (most common — submersible, booster, circulation) | Free |
| 8413.81.00.40 | Other pumps for liquids — other Non-centrifugal water pumps (e.g., hand, jet, other) | Free |
| 8413.70.10.00 | Stock pumps imported for use with machines for making cellulosic pulp, paper or paperboard Centrifugal stock pumps for pulp/paper machinery | Free |
| 8413.30.90.90 | Fuel, lubricating or cooling medium pumps for internal combustion piston engines — other Engine coolant / water pumps for internal combustion engines | 2.5% |
| 8413.30.10.00 | Fuel-injection pumps for compression-ignition engines Diesel fuel-injection pumps (engine fuel system) | 2.5% |
| 8413.91.90.85 | Parts of pumps for liquids — other Pump parts (impellers, housings, seals kits, etc.) | Free |
| 8413.91.20.00 | Parts of stock pumps imported for use with cellulosic pulp/paper machinery Parts of pulp/paper stock pumps | Free |
| 8413.91.10.00 | Parts of fuel-injection pumps for compression-ignition engines Parts of diesel fuel-injection pumps | 2.5% |
Water pumps are associated with heading 8413 of the Harmonized Tariff Schedule, which covers pumps for liquids, whether or not fitted with a measuring device. The key questions are the pump's operating principle and whether it is a stand-alone pump or part of an engine.
Most ordinary water pumps — submersible, booster, circulation and similar units — operate by centrifugal action and point toward 8413.70 (other centrifugal pumps), which is generally duty-free. Water pumps that are not centrifugal, such as certain hand pumps, jet pumps and other positive-displacement designs for water, point toward 8413.81 (other pumps for liquids), also generally duty-free.
Pumps designed as part of an internal combustion piston engine are treated differently. Engine coolant pumps — the automotive 'water pump' that circulates coolant — along with fuel and lubricating pumps for engines, point toward 8413.30 at a rate around 2.5%. This is an important distinction: an engine water pump and a stand-alone centrifugal water pump can carry different duty even though both move water.
Parts of pumps point toward 8413.91, with the rate following the type of pump the part belongs to — parts of engine pumps around 2.5% and parts of other pumps generally duty-free.
The reliable approach is to review whether the pump is a stand-alone centrifugal pump (8413.70), a stand-alone non-centrifugal pump (8413.81), or a pump that forms part of an internal combustion engine (8413.30), and then whether the item is a complete pump or a part.
Most stand-alone water pumps are duty-free: centrifugal pumps under 8413.70 and other liquid pumps under 8413.81 both generally carry a Free rate. Pumps that are part of an internal combustion engine — engine coolant/water pumps and fuel-injection pumps under 8413.30 — carry a general rate around 2.5%, as do parts of those engine pumps under 8413.91. Parts of other pumps are generally duty-free. Preferential rates under free trade agreements may apply for qualifying origins. Whether the pump is stand-alone or engine-mounted is the main driver of the duty.
