Duluth Port Reefer: Temperature-Controlled Drayage

Reefer port work in Duluth requires a well-maintained unit with reliable temperature monitoring, TWIC card for port access, and proper insurance. Many port loads require continuous temperature recording (data loggers) for compliance. We ensure you meet all requirements before dispatching to port facilities.

The Port of Duluth-Superior handles approximately 35 million tons annually, primarily iron ore pellets from the Mesabi Range, grain exports, coal, and limestone. Truck-to-ship and rail-to-ship transfers are common. The port operates seasonally, with shipping from late March through January.

Duluth's steep terrain from Lake Superior to the hilltop creates challenging truck routes with significant grades. Winter conditions are severe with lake-effect snow. I-35 through the city narrows and the Thompson Hill descent requires careful braking for loaded trucks. Reefer carriers face additional challenges: high ambient temperatures strain reefer units, increasing fuel burn 20-30%. Pre-cool trailers before arrival and monitor temperature logs continuously.
