Law

Unlikely to pass

This bill tries to change a very old law that protects American shipping jobs. Most members of Congress prefer to keep those protections in place to support local workers and businesses.

Key Points

This bill would cancel a 1906 law that says only American-made ships can clear out mud and sand from U.S. harbors. This work is called dredging, and it is needed to keep the water deep enough for big cargo ships to pass through.
By letting foreign companies bid on these jobs, the bill aims to make port upgrades cheaper and faster. Right now, only a few U.S. companies do this work, which can lead to high costs and long delays for local communities.
Supporters say this will help fix supply chain problems by making it easier for the world's largest ships to dock in America. However, some people worry that using foreign ships could take away jobs from American sailors and shipbuilders.
