HS Code 8408.10 – Engines; for marine propulsion, compression-ignition internal combustion piston engines (diesel or semi-diesel engines)
HS code 8408.10 is the 6-digit subheading for engines, for marine propulsion, compression-ignition internal combustion piston engines (diesel or semi-diesel engines). It is used for marine diesel engines, commercial ship engines, yacht diesel engines, fishing boat diesel engines and tugboat engines.
What HS 8408.10 covers
This HS code covers compression-ignition internal combustion piston engines, commonly known as diesel or semi-diesel engines, specifically designed for marine propulsion. These robust engines power a vast array of vessels, from large commercial ships, fishing trawlers, and tugboats to luxury yachts and smaller workboats. International trade is substantial, driven by global shipping, commercial fishing, and the maritime leisure industry. Major exporters are countries with strong heavy machinery and shipbuilding industries, such as Germany, Japan, South Korea, and the USA. Importers include shipyards, marine equipment distributors, and vessel owners worldwide. Key trade factors include engine power output, fuel efficiency, reliability, emissions compliance (IMO Tier regulations), and the availability of global service networks. The market is highly competitive, with a focus on long-term operational costs and environmental performance.

Codes often confused with 8408.10
Common mistake. This code is clearly defined by its "marine propulsion" and "compression-ignition" characteristics, distinguishing it from 84072x (marine spark-ignition) and 840820 (vehicle diesel engines).
Top exporters and importers of HS code 840810, 2025
In 2025, the largest exporter of HS code 840810 in UN Comtrade data was South Korea, with 28% of world exports; the largest importer in UN Comtrade data was China, with 33% 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).
