The Merchant Marine Act of 1920 (Jones Act)

The Merchant Marine Act of 1920, known as the Jones Act, is a U.S. law that requires goods shipped between U.S. ports to be transported on ships built, owned, and operated primarily by U.S. citizens or companies. Its purpose is to ensure a strong domestic maritime industry, support national security, and promote maritime jobs. The act also mandates specific standards for safety and labor conditions on these ships. While it helps maintain a skilled maritime workforce and fleet, critics argue it can increase shipping costs and limit competition.
