Title 46 › Subtitle V — Merchant Marine › Part G — Restrictions and Penalties › CHAPTER 581 — RESTRICTIONS AND PENALTIES › § 58108
Carriers must not give a lower rate for transportation covered by subtitle IV of title 49 just because the people or goods are going to or coming from a port in a U.S. territory, possession, or a foreign country when that movement involves a ship in foreign commerce. The lower rate cannot be for the same distance, same direction, and same route as a trip done entirely inside the United States, unless the ship was documented under U.S. law at the time. If the Secretary of Transportation finds that U.S.-documented ships are not providing enough service to those ports, the Secretary tells the Surface Transportation Board. The Board can then suspend the rule for rail rates to or from those ports for the time and on the terms the Secretary sets. When the Secretary later says U.S.-documented ships are providing enough service, the Board can end the suspension.
