The Jones Act

The Jones Act, officially known as the Merchant Marine Act of 1920, is a U.S. federal law that requires maritime shipping between U.S. ports to be carried out on ships that are built, owned, and operated by American companies and crewed primarily by U.S. citizens. This law aims to support national security, maritime industry jobs, and the U.S. fleet’s readiness. While it helps sustain American maritime capabilities, critics argue it can increase shipping costs and limit flexibility, especially in crises or emergencies where foreign vessels could potentially be more efficient.
