Yes. Buoys and beacons placed in US navigable waters typically require authorization from the US Coast Guard under 33 CFR Part 66 (private aids to navigation) or from the Army Corps of Engineers for structures affecting navigation. Importation through CBP is separate from these deployment permits, and importers should initiate agency coordination well before planned installation.
Floating structures made primarily of steel may be subject to Section 232 tariffs, which apply to steel mill products and certain downstream steel-intensive articles. Whether a specific floating tank or cofferdam triggers Section 232 depends on its classification and the applicable product exclusion status. Importers should review current CBP and Commerce Department guidance and consult a licensed customs broker for steel-intensive floating structures.
