Product classification
HS code for Truck engine: 8407.34
Engines, reciprocating piston engines, of a kind used for the propulsion of vehicles of chapter 87, of a cylinder capacity exceeding 1000cc.
Classification of truck engine under HS 8407.34
The classification of a truck engine under HS code 8407.34 is determined by its technical specifications as a spark-ignition, reciprocating piston internal combustion engine. To qualify for this specific code, the engine must have a cylinder capacity exceeding 1,000cc and be designed for the propulsion of vehicles classified within Chapter 87, which encompasses motor vehicles for the transport of persons or goods. This code is part of a hierarchical structure where engines are first categorized by their ignition type (spark-ignition vs. compression-ignition) and then by their displacement. Even if an engine is intended for heavy-duty industrial trucks, if it utilizes spark plugs for ignition and exceeds the 1,000cc threshold, it must be classified here. The classification remains consistent whether the engine is imported as a standalone unit or with essential auxiliary components like the fuel pump or water pump, provided it retains the essential character of a complete engine.

Codes often confused with 8407.34
Common mistake. The most frequent misclassification occurs with HS code 8408.20. While 8407.34 covers spark-ignition engines, 8408.20 is reserved for compression-ignition (diesel or semi-diesel) engines. Since the vast majority of commercial trucks operate on diesel, importers often default to 8408.20 without verifying the ignition system. Additionally, engines under 1,000cc are classified under 8407.33, so displacement must be verified via technical data sheets.
Top exporters and importers of HS 840734 (the code used for truck engine), 2025
In 2025, the largest exporter of HS 840734 (the code used for truck engine) in UN Comtrade data was the United States, with 20% of world exports; the largest importer in UN Comtrade data was the United States, with 24% of world imports. Mexico reports $451M of its heading 8407 imports without product detail (confidential), so it may also belong among the top importers.

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).
