Floating platforms used for offshore drilling may qualify for temporary importation treatment under certain conditions, including use outside US territorial waters. The applicability depends on the specific operational arrangement, duration, and applicable CBP regulations. A licensed customs broker with offshore energy experience should be consulted to determine the correct entry type.

A dredger is specifically equipped to excavate and remove material from the seabed or riverbed, while a floating crane is a platform-mounted lifting device used to handle heavy loads. If a vessel performs both functions, classification follows its principal design purpose as evidenced by its technical specifications and equipment configuration.
