HS Code 8603.90 – Railway or tramway coaches, vans and trucks; self-propelled, powered other than from an external source of electricity (excluding those of heading no. 8604)

HS code 8603.90 is the 6-digit subheading for railway or tramway coaches, vans and trucks, self-propelled, powered other than from an external source of electricity (excluding those of heading no. 8604). It is used for diesel Multiple Units (DMUs), hydrogen trains, bi-mode trains, diesel railcars and gas turbine railcars.

What HS 8603.90 covers

This HS code covers self-propelled railway or tramway coaches, vans, and trucks powered by means other than an external source of electricity, excluding maintenance vehicles. This category primarily includes Diesel Multiple Units (DMUs), but also encompasses emerging technologies like hydrogen-powered trains or bi-mode trains operating on non-electrified lines. These vehicles are crucial for regional and branch line services where electrification is not economically viable or technically feasible. Importers include regional railway operators and leasing companies, with major rolling stock manufacturers acting as exporters. The trade is influenced by the need for flexible, self-contained transport solutions, often in areas with lower passenger density. Key factors include fuel efficiency, emissions regulations, and the ability to operate independently of overhead lines or third rails.

Codes often confused with 8603.90

Common mistake. This code is differentiated from 8603.10 (externally electric powered vehicles) and 8604.00 (railway maintenance vehicles), as it covers self-propelled passenger/freight vehicles with internal combustion or alternative non-electric external power.

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).
