Floating structures, tanks, coffer-dams, landing stages, buoys and beacons.

Classification of floating dock under HS 8907.90

Floating docks are classified under HS code 8907.90. This code is situated within Chapter 89, which covers ships, boats, and floating structures. Heading 8907 is a broad category for "other floating structures," which includes tanks, coffer-dams, landing stages, buoys, and beacons. A floating dock is a buoyant platform used in ports, marinas, or industrial sites to provide a stable surface for mooring vessels or for loading and unloading cargo. Unlike vessels classified under 8901 to 8906, these structures do not typically possess a hull designed for navigation or a means of self-propulsion. Their primary function is buoyancy and stability in a fixed or semi-fixed location. The distinction between a vessel and a floating structure is often based on the "ability to navigate." While a floating dock can be towed, it is not designed for independent travel across open water. This lack of navigational equipment and hull design is why it is excluded from headings 8901 through 8906 and placed in the residual category 8907.90. The classification is based on the structural nature of the object as a floating utility rather than a transport vehicle.

Codes often confused with 8907.90

Common mistake. A common misclassification occurs with HS code 8905.90, which covers floating docks that are essentially vessels, such as floating dry-docks used for ship repair that can be submerged and raised. If the structure has the characteristics of a ship or is a complex navigational aid, it may fall under 8905. Furthermore, if a dock is a permanent fixture made of steel and attached to the shore in a way that it is no longer "floating" but a "structure," it might be classified under HS code 7308 as a structure of iron or steel.

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).
