U.S. grain and coke exports boosted overall shipping volumes through St. Lawrence Seaway in June.

Total cargo tonnage shipments, from March 22 to June 30, via the St. Lawrence Seaway totaled 11.9 million metric tons, down 8.3% compared to 2021 but gaining ground in comparison to April, when it was down 18% at the start of the season.

Other system-wide highlights include an increase in project cargo such as wind energy components and a 55% increase in coke shipments, including exports to Europe for cement production.

U.S. grain shipments via the Great Lakes-Seaway system totaled 414,000 metric tons from March 22 to June 30, up 37% compared to the same period in 2021. Much of the increase is due to exports of corn and soybeans.

The rise in shipments, which are predominantly heading to Europe and North Africa, are in part due to shifting global grain trading patterns as the conflict between Russia and the Ukraine — both major grain exporters — continues.

“International trade has been a major driver of Great Lakes-St. Lawrence Seaway shipping this season, with corn, soybeans, coke and containerized goods heading out and steel and wind energy components being shipped in,” said Bruce Burrows, President and CEO, of the Chamber of Marine Commerce. “American businesses recognize that it is more important than ever to have this reliable, cost-efficient trade and transportation route, particularly in these high-inflation, uncertain times.”

Inbound wind energy cargoes and bagged minerals delivered the general cargo boost in June, with nearly 13,000 short tons arriving at the Duluth Cargo Connect facilities. That float lifted the season-to-date general cargo tonnage total past 27,280 short tons, which exceeds the five-season average pace through June 30 by a robust 33%.
