Iron ore shipments on the Great Lakes jumped 8.4% in May, as steel demand held firm and carriers ran at full capacity across the system.
The Lake Carriers’ Association said iron ore cargos reached 5.4 million tons for the month. That total was 4.7% above the five-year May average. Year-to-date shipments rose to 12.2 million tons, up 4.1% from the same period a year earlier.
May shipments top recent norms
The May gain extended a steady start to the shipping season. Volumes stayed ahead of recent norms as ore moved from Lake Superior loading docks to lower-lakes steelmaking centers.
| Metric | May 2026 | Change vs 2025 |
|---|---|---|
| Total Shipments | 5.4 Million Tons | +8.4% |
| Year-to-Date | 12.2 Million Tons | +4.1% |
| 5-Year Average | +4.7% | N/A |
Marquette and Cleveland lead activity
Marquette and Cleveland led the monthly surge. Marquette, Michigan, shipped 1.04 million tons. Cleveland, Ohio, handled 447,139 tons.
Those two ports were among the clearest signs of steady mill demand. They also reflected a fleet that stayed fully deployed through the month, with few visible disruptions to ore flows.
Steel demand supports the trade
The trade remains central to the U.S. industrial supply chain. Great Lakes iron ore feeds domestic steel mills that rely on regular vessel traffic during the navigation season.
For operators, the May figures point to stable logistics and solid end-market demand. For the broader sector, they reinforce the role of Great Lakes shipping in keeping raw materials moving to steel producers.
Stability also supports the global mining outlook 2026.
