HS Code 8407.29 – Engines; for marine propulsion, (other than outboard motors), spark-ignition reciprocating or rotary internal combustion piston engines
HS code 8407.29 is the 6-digit subheading for engines, for marine propulsion, (other than outboard motors), spark-ignition reciprocating or rotary internal combustion piston engines. It is used for inboard gasoline engines, sterndrive gasoline engines, marine V8 engines, marine jet propulsion engines and high-performance marine engines.
What HS 8407.29 covers
This category covers spark-ignition internal combustion engines used for marine propulsion, excluding outboard motors. These are typically inboard engines, sterndrive engines, or jet propulsion units found in larger recreational yachts, speedboats, and some smaller commercial vessels. The trade involves manufacturers supplying boat builders globally, as well as aftermarket sales for engine replacements or upgrades. Countries with significant shipbuilding industries, particularly for pleasure craft, are key players in both importing and exporting these sophisticated power units. Importers often include specialized marine engine distributors, boatyards, and original equipment manufacturers (OEMs). Exporters are usually large-scale engine producers. Important trade factors include engine displacement, horsepower, fuel type (gasoline), emissions compliance, and integration with complex marine systems, making technical specifications and certifications critical for international transactions.

Codes often confused with 8407.29
Common mistake. This code is distinct from 840721 (outboard motors) due to its "other than outboard motors" clause, and from 840810 (marine diesel engines) by its spark-ignition characteristic.
Top exporters and importers of HS code 840729, 2025
In 2025, the largest exporter of HS code 840729 in UN Comtrade data was Japan, with 45% of world exports; the largest importer in UN Comtrade data was Brazil, with 17% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
