Charleston Harbor would become the deepest port in the Southeast at 52 feet under a dredging project, allowing all container terminals to handle the biggest ship at any tide, according to FreightWaves.[^1]

The depth would exceed current Southeast ports, though no fact states which port holds the current record or by how much. The project is designed to let fully laden ultra-large container vessels enter and leave regardless of tide.[^1]

A 2012 Federal Reserve Bank of New York study found that shipping a container from the U.S. East Coast to Puerto Rico cost $3,063, versus $1,504 to ship one to the nearby Dominican Republic on a foreign vessel.[^2] The Congressional Research Service estimated in 2020 that a U.S.-built tanker costs about four times the global price and a U.S.-built container ship about five times.[^3]
