Imports at the nation’s major retail container ports should see steady increases through the summer and into the fall, according to the monthly Global Port Tracker report released by the National Retail Federation (NRF) and Hackett Associates.

“Regardless of whether the sales come in their stores or through their websites, retailers see that consumers are buying more this year and they’re importing the goods needed to meet the demand,” said Jonathan Gold, NRF vice president for supply chain and customs policy. “With unemployment at its lowest level in a decade and the economy adding jobs, retailers expect shoppers to continue to increase their spending.”

Ben Hackett, Hackett Associates founder, added, “In the United States, the economy continues to slowly grow. Gross domestic product was lower than expected in the first quarter but unemployment has dropped to levels not seen since before the Great Recession and, best of all, labor employment has increased dramatically. Our view, therefore, remains unchanged: There is nothing to worry about in the first half of the year, and growth is expected to continue in the second half even if it comes at a slower rate.”

Ports covered by Global Port Tracker handled 1.53 million Twenty-Foot Equivalent Units (TEU) in March, up 6.8% from February, and 15.8% from unusually low numbers in March 2016.

April was estimated at 1.56 million TEU, up 8.3% from the same time last year. May is forecast at 1.66 million TEU, up 2.6% from last year; June at 1.62 million TEU, up 3.3%; July at 1.68 million TEU, up 3.1%; August at 1.74 million TEU, up 1.6%, and September at 1.65 million TEU, up 3.6%.

The first half of 2017 is expected to total 9.5 million TEU, up 5.6% from the first half of 2016. Cargo volume for 2016 totaled 18.8 million TEU, up 3.1% from 2015, which had grown 5.4% from 2014.

NRF has forecast that 2017 retail sales–excluding automobiles, gasoline and restaurants–will increase 3.7-4.2% over 2016, driven by job and income growth coupled with low debt.
