(a) No vessel shall transport, either directly or by way of a foreign port, any passenger or merchandise between points in the United States embraced within the coastwise laws, including points within a harbor, or merchandise for any part of the transportation between such points, unless it is:

(b)

(c) Any vessel of the United States, whether or not entitled under paragraph (a) of this section to engage in the coastwise trade, and any foreign vessel may proceed between points in the United States embraced within the coastwise laws to discharge cargo or passengers laden at a foreign port, to lade cargo or passengers for a foreign port, in ballast, or to transport certain articles in accordance with § 4.93. Cargo laden at a foreign port may be retained onboard during such movements. Furthermore, certain barges of United States or foreign flag may transport transferred merchandise between points in the United States embraced within the coastwise laws, excluding transportation between the continental United States and a noncontiguous point in the United States embraced within the coastwise laws, in accordance with § 4.81a.

(d) No vessel owned by a corporation which is a citizen of the United States under the Act of September 2, 1958 (46 U.S.C. 12118), shall be used in any trade other than the coastwise and shall not be used in that trade unless it is properly documented for such use or is exempt from documentation and is entitled to or, except for its tonnage, would be entitled to a coastwise license. Such a vessel shall not be documented for nor engage in the foreign trade or the fisheries and shall not transport merchandise or passengers coastwise for hire except as a service for a parent or a subsidiary corporation as defined in the aforesaid Act or while under demise or bareboat charter at prevailing rates for use otherwise than in trade with noncontiguous territory of the United States to a common or contract carrier subject to part III of the Interstate Commerce Act, as amended (49 U.S.C. 901 through 923), which otherwise qualifies as a citizen of the United States under section 2 of the Shipping Act, 1916, as amended (46 U.S.C. 50501), and which is not connected, directly or indirectly, by way of ownership or control with such owning corporation.

(e) No vessel which has acquired the lawful right to engage in the coastwise trade, by virtue of having been built or documented under the laws of the United States, will have the right to engage in such trade if it:

(f) No foreign-built vessel owned and documented as a vessel of the United States prior to February 1, 1920, by a citizen nor one owned by the United States on June 5, 1920, and sold to and owned by a citizen, shall engage in the American fisheries, but it is otherwise unlimited as to trade so long as it continues in such ownership (section 22, Merchant Marine Act, of June 5, 1920; 46 U.S.C. 13). No foreign-built vessel which is owned by a citizen, but which was not so owned and documented on February 1, 1920, or which was not owned by the United States on June 5, 1920, shall engage in the coastwise trade or the American fisheries. No foreign-built vessel which has been sold, leased, or chartered by the Secretary of Commerce to any citizen, shall engage in the American fisheries, but it is otherwise unlimited as to trade so long as it continues in such ownership, lease, or charter (section 9 of the Act of Sept. 7, 1916, as amended, 46 U.S.C. 56101 and 57109). A vessel engaged in taking out fishing parties for hire, unless it intends to proceed to a foreign port, is considered to be engaged in the coastwise trade and not the fisheries.

(g) Certain vessels not documented under the laws of the United States which are acquired by or made available to the Secretary of Commerce may be documented under section 3 of the Act of August 9, 1954 (50 U.S.C. 198). Such vessels shall not engage in the coastwise trade unless in possession of a valid unexpired permit to engage in that trade issued by the Secretary of Commerce under authority of section 3(c) of the said Act.

(h) A vessel which is at least 50 percent owned by a citizen as defined in 46 CFR subpart 68.05, and which, except for citizenship requirements, is otherwise entitled to be documented with a coastwise endorsement, may be documented with a limited coastwise endorsement, provided the vessel is owned by a not-for-profit oil spill response cooperative or by one or more members of such a cooperative who dedicate the vessel to the use of the cooperative (46 U.S.C. 12117). Notwithstanding 46 U.S.C. 55102, a vessel may be documented with such a limited endorsement even if formerly owned by a not-for-profit oil spill response cooperative or by one or more members thereof, as long as the citizenship criteria of 46 CFR subpart 68.05 are met. A vessel so documented may operate on the navigable waters of the United States or in the Exclusive Economic Zone only for the purpose of training for oil spill cleanup operations; deploying equipment, supplies and personnel for cleanup operations; and recovering and/or transporting oil discharged in a spill. Such vessel may also engage in any other employment for which a registry or fishing endorsement is not required, and may qualify to operate for other purposes by meeting the applicable requirements of 46 CFR part 67.

(i) Any vessel, entitled to be documented and not so documented, employed in a trade for which a Certificate of Documentation is issued under the vessel documentation laws (see § 4.0(c)), other than a trade covered by a registry, is liable to a civil penalty of $500 for each port at which it arrives without the proper Certificate of Documentation on or before November 2, 2015, and $1,453 for each port at which it arrives without the proper Certificate of Documentation after November 2, 2015 (19 U.S.C. 1706a, as adjusted by the Federal Civil Penalties Inflation Adjustment Act Improvements Act of 2015). If such a vessel has on board any foreign merchandise (sea stores excepted), or any domestic taxable alcoholic beverages, on which the duty and taxes have not been paid or secured to be paid, the vessel and its cargo are subject to seizure and forfeiture.
