Port Houston’s monthly container flows slip in September

Port Houston handled 325,588 twenty-foot equivalent units in September, a year-over-year (y/y) decrease of 8% compared to the same period last year. 

Roger Guenther, executive director at Port Houston, said cargo traffic at the port has remained steady in 2023 but has been lower than the record results of 2022.

“Our overall tonnage in September across all facilities is down versus 2022, which to remind everyone 2022 was a record year,” Guenther said during the port’s monthly commission meeting Tuesday. “Loaded boxes are still coming through our port and we expect it to continue that way. It’s kind of the decline of the empty containers being exported to Asia that is driving the [monthly] totals down a little bit.”


Loaded imports were down 12% y/y at 156,161 TEUs, while loaded exports were up 21% y/y in September at 124,739 TEUs.

Empty import containers increased 63% y/y in September at 16,208 TEUs, while empty export containers decreased 55% y/y to 28,480 TEUs.

Total revenue tonnage was down 16% y/y at 4.9 million tons.

Imports of steel products were down 20% y/y in September at 349,509 tons. General cargo imports were down 37% y/y at 622,911 tons. Container imports decreased 10% y/y to 1.47 million tons.


Exports of steel products were down 94% y/y to 2,992 tons, while general exports decreased 38% y/y to 876,059 tons. Container exports increased 15% to 1.6 million tons.

Chief Port Operations Officer Jeff Davis said on Sept. 26 the port handled 15,491 gate transactions at its Barbours Cut and Bayport container terminals, its busiest day of the month. 

“As Roger mentioned, we’re just not seeing those export empties [containers] being returned as imports like we did last year, but we continue to have a solid year,” Davis said during Tuesday’s meeting.

Port Houston recorded 688 ship calls in September, a 2% y/y increase, while barge calls totaled 287, a 37% y/y decline.
