Dry Bulk

The figure below shows the total volume of imports, exports, and domestic freight handled by each of the top 25 ports by tonnage. The Nation's dry bulk ports are primary located along the Great Lakes, the Mississippi River, and the Gulf coast.
The top 25 dry bulk ports handled a total of 672 million tons of cargo, accounting for 70.4 percent of the dry bulk tons handled by the top 100 ranked dry bulk ports. The top 100 ports account for 94.2 percent of  total dry bulk tonnage handled by U.S. ports. The port of South Louisiana remained in the top spot and handled by far the greatest volume of dry bulk cargo, more than 3 and 4 times, respectively, than the amount handled by the next ports on the list—the ports of New Orleans and the Plaquemines.[1]
