HS Code 8905.90 – Vessels; light, fire-floats, floating cranes and other vessels, the navigability of which is subsidiary to their main function, floating docks
HS code 8905.90 is the 6-digit subheading for vessels, light, fire-floats, floating cranes and other vessels, the navigability of which is subsidiary to their main function, floating docks. It is used for floating dry docks, offshore construction barges, fireboats, floating power plants and dredging vessels.
What HS 8905.90 covers
This HS code covers a unique segment of the maritime industry, focusing on specialized vessels whose primary function isn't transportation but rather operational support or specific tasks, with navigability being secondary. This includes robust vessels like floating cranes used in heavy construction or salvage operations, dedicated fire-fighting vessels (fire-floats), and crucial infrastructure such as floating docks for ship repair and maintenance. The trade involves heavy engineering and specialized shipbuilding, with major maritime nations and those with significant port infrastructure being key players. Countries with extensive coastlines, busy shipping lanes, or offshore industries (e.g., oil and gas exploration) are significant importers and exporters. These vessels are often custom-built, high-value assets, reflecting complex engineering, specific operational requirements, and substantial investment in maritime infrastructure.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
