Product classification
HS code for Automotive 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 automotive engine under HS 8407.34
The classification of automotive engines under HS code 8407.34 is based on the engine type, its intended use, and its cylinder capacity. Heading 8407 covers spark-ignition reciprocating or rotary internal combustion piston engines. Subheading 8407.34 specifically targets reciprocating piston engines used for the propulsion of vehicles classified in Chapter 87 (such as cars and trucks) with a cylinder capacity exceeding 1,000 cc. This classification is distinct from engines used for marine propulsion or stationary power generation. The determination of the cylinder capacity is a critical technical factor for this code, as smaller engines are categorized under different subheadings (8407.31 to 8407.33). The engine must be a spark-ignition type, typically running on gasoline (petrol). This classification follows GRI 1 and 6, ensuring that the specific displacement threshold is met. These engines are the primary power units for the majority of passenger cars and light commercial vehicles globally.

Codes often confused with 8407.34
Common mistake. The most frequent misclassification is with HS code 8408.20, which covers compression-ignition internal combustion piston engines (diesel or semi-diesel) for vehicles. Even if the displacement is the same, the ignition method determines the heading. Another error is using 8407.33 for engines that are exactly 1,000 cc or less; 8407.34 is strictly for those exceeding 1,000 cc. Additionally, engines for aircraft (8407.10) or marine vessels (8407.21) must be excluded even if their displacement is similar.
Top exporters and importers of HS 840734 (the code used for automotive engine), 2025
In 2025, the largest exporter of HS 840734 (the code used for automotive 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).
