This bill temporarily exempts vessels using the Port of Baltimore from certain Jones Act restrictions, which normally require ships operating in U.S. waters to be American-built, American-owned, and American-crewed. The exemption applies to any vessel arriving at or departing from the Helen Delich Bentley Port of Baltimore after the bill's enactment and remains in effect for five years. The measure aims to support Baltimore's recovery, likely in response to the March 2024 Francis Scott Key Bridge collapse that temporarily closed the port and disrupted shipping. By allowing foreign vessels greater access to the port, the bill seeks to restore cargo capacity and economic activity. The exemption is temporary and automatically expires five years after the law takes effect.
