U.S. imports of Fuel, Lubricating & Cooling Medium Pumps for Internal Combustion Piston Engines (HS 841330) totaled $257.7M in August 2026, imported from 104 countries.
Importers of Fuel, Lubricating & Cooling Medium Pumps for Internal Combustion Piston Engines paid $30.3M in duties in August 2026, an average duty rate of 11.63% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataFuel-injection pumps for compression-ignition (diesel) engines — classified under 8413301000 — and the broader range of fuel, lubricating-oil, and coolant pumps for gasoline and diesel piston engines make this heading a critical node in automotive and heavy-equipment supply chains. Mexico and Japan lead US imports, reflecting deeply integrated OEM and aftermarket supply networks for passenger vehicles and commercial trucks. Germany also ranks among the top suppliers, consistent with its role in diesel injection system manufacturing. Importers should note that fuel-injection pumps for compression-ignition engines occupy a dedicated tariff line separate from all other pump types in this heading.

Compression-ignition (diesel) fuel-injection pumps are precision, high-pressure components with distinct engineering characteristics and trade volumes that justify their own statistical tracking. All other fuel pumps, lubricating pumps, and cooling medium pumps for piston engines — whether for gasoline or diesel applications — fall under the remaining lines in 841330, which are further subdivided by function.
Yes — cooling medium pumps for internal combustion piston engines, including water pumps for gasoline engines, are specifically provided for under 8413309090. The pump must be designed for use in a piston engine; water pumps for industrial or HVAC applications would classify elsewhere in Chapter 84.
