Port of
Duluth-Superior
Print

Moving the earth. All over the world.

What's inside the cargo holds of vessels moving in and out of this port isn't merely cargo, it's the commercial lifeblood of this nation's heartland. And we move mountains of it every year - nearly 40 million short tons on average - commodities like iron ore, coal, limestone, cement, grain and, quite literally, the salt of the earth.

  • Annual average of 1,000 vessel visits
  • Principal outbound cargoes: Iron ore, coal, grain
  • Principal inbound cargoes: limestone, cement, salt, wood products, steel coil, wind turbine components and other heavy equipment for energy-related projects
