The exceptions to the 180-day rule apply to each individual vessel that meets the requirements of the general license irrespective of any code-sharing arrangement. Thus, any shipping company may deploy a vessel in a broader shipping arrangement and, so long as the vessel meets the terms of the general license, that vessel may enter a U.S. port accordingly. There is no requirement for authorization of the individual companies or the broader code-sharing arrangement. Code-sharing agreements do not affect the general license or its requirements.
