Product classification
HS code for Car 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 car engine under HS 8407.34
The classification of internal combustion engines is highly specific based on the method of ignition and the cylinder capacity. HS code 8407.34 applies to spark-ignition reciprocating piston engines used for the propulsion of vehicles classified in Chapter 87, provided they have a cylinder capacity exceeding 1000cc. This code is part of Chapter 84, which encompasses machinery and mechanical appliances. The distinction of "spark-ignition" is critical, as it separates petrol (gasoline) engines from diesel engines. Furthermore, the capacity threshold of 1000cc distinguishes these larger automotive engines from smaller engines used in motorcycles or small utility vehicles. The engine must be presented as a functional unit, though it may be missing certain peripheral components like the battery or radiator, provided it retains the essential character of a reciprocating piston engine for vehicle propulsion.

Codes often confused with 8407.34
Common mistake. The most common misclassification is with HS code 8408, which is reserved for compression-ignition internal combustion piston engines (diesel or semi-diesel). Another frequent error involves HS code 8407.33, which is for engines with a capacity between 250cc and 1000cc. Importers must verify the exact displacement to choose between these subheadings. Additionally, electric motors for electric vehicles (EVs) are classified under 8501, not 8407, as they do not utilize internal combustion.
Top exporters and importers of HS 840734 (the code used for car engine), 2025
In 2025, the largest exporter of HS 840734 (the code used for car 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).

Questions about car engine
What is the HS code for Car engine?
The HS code for Car engine is 840734 (Engines; reciprocating piston engines, of a kind used for the propulsion of vehicles of chapter 87, of a cylinder capacity exceeding 1000cc). For a spark-ignition (petrol) engine with a displacement exceeding 1000cc, the HS code is 8407.34.
How do I classify Car engine for customs?
Car engine is classified under HS code 840734 — Engines; reciprocating piston engines, of a kind used for the propulsion of vehicles of chapter 87, of a cylinder capacity exceeding 1000cc. This is a 6-digit subheading level code.
Are used engines classified differently?
No, the HS code remains 8407.34 for used or reconditioned engines, though specific national customs regulations may require additional documentation for used auto parts.
Which countries are the top exporters of car engine (HS 840734)?
