The port reported 449,568 twenty-foot-equivalent units were moved in March, a 30.9 percent decrease compared to March of last year. It was the lowest amount of monthly cargo moving through the port since February 2009.

“We’ve had two serious shocks to our supply chain system. First, the trade war between the U.S. and China, and now the COVID-19 pandemic,” said Gene Seroka, executive director of the Port of Los Angeles.

In late-March, the port reported it was operating at 80 percent of normal business.

“With U.S. retailers and cargo owners scaling back orders, volumes are soft even though factories in China are beginning to produce more,” he said. “Amidst this public health crisis, there will be uncertain months ahead in the global supply chain.”
