HS Code 8907.90 – Floating structures; tanks, coffer-dams, landing stages, buoys and beacons

HS code 8907.90 is the 6-digit subheading for floating structures, tanks, coffer-dams, landing stages, buoys and beacons. It is used for floating storage tanks, coffer-dams, floating docks, navigation buoys and light beacons (floating).

What HS 8907.90 covers

This broad category encompasses various non-self-propelled floating structures critical for maritime infrastructure, navigation, and industrial operations. It includes items like floating tanks for storage, coffer-dams for construction, landing stages for docking, and buoys and beacons for marking waterways. International trade involves specialized engineering firms, port authorities, offshore energy companies, and maritime safety organizations. These structures are often large, custom-built, and require significant logistical planning for international transport and installation. Their value is tied to their structural integrity, material science, and specific functional design for harsh marine environments. Exporters are typically countries with advanced heavy manufacturing and maritime engineering capabilities, while importers are found globally wherever port development, offshore projects, or waterway management is underway.

Codes often confused with 8907.90

Common mistake. Could be confused with 8905 (light-vessels, fire-floats, dredgers) if they have propulsion or are specialized vessels, or even 7308 (structures of iron/steel) if their 'floating' nature isn't emphasized. The key is their static or semi-static floating function without self-propulsion.

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).
