Port Houston handled 369,899 twenty-foot equivalent units in July, a 6% decline from the same month a year earlier, as container growth at the Gulf Coast gateway moderated following stronger activity earlier in 2026. The July figure compares with 392,829 TEUs in July 2025. Port Houston is one of the fastest-growing container gateways on the U.S. Gulf Coast, and monthly volume swings there are closely watched as a barometer of southern U.S. import demand.

Despite the monthly drop, container activity remained slightly ahead of last year's pace through the first seven months of 2026. The port handled nearly 2.6 million TEUs from January through July, up 1% from 2.56 million TEUs in the same period of 2025. Port officials said overall container growth has moderated after stronger activity earlier in the year associated with frontloading — a pattern in which shippers move cargo earlier than usual, often ahead of expected changes in trade costs or policy, which can pull volume forward and leave later months softer by comparison.

Loaded imports totaled 181,808 TEUs in July, down 3% year over year from 187,367 TEUs, while loaded exports declined 6% to 124,814 TEUs from 133,137 TEUs. For the year to date, loaded imports remained a source of growth, rising 5% to 1.21 million TEUs. Loaded exports totaled 925,781 TEUs through July, down 1% from the same period last year.

East Asia continued to drive import growth, with loaded container imports from the region up 10% year to date, representing 57% of total import volume. According to a news release, port officials said apparel, resins and plastics, machinery and electronics helped drive the increase.

Total revenue tonnage at Port Houston's public facilities reached 4.57 million tons in July, down 12% from 5.19 million tons a year earlier. Through July, the port handled 32.81 million tons, essentially flat compared with 32.65 million tons during the first seven months of 2025.

General cargo was one of the strongest categories during the month. Port Houston handled 104,048 tons of general cargo in July, a 42% increase from 73,290 tons a year earlier, bringing year-to-date general cargo to 796,982 tons, up 35% from 590,555 tons in 2025.

Steel continued to move in the opposite direction. Steel tonnage fell 37% year over year in July to 357,625 tons, and steel imports declined 36% to 331,271 tons. Through July, total steel tonnage was down 18% to 2.34 million tons.

Other bulk categories posted stronger year-to-date results. Dry bulk tonnage totaled 3.56 million tons through July, up 1%, while liquid bulk increased 13% to 1.89 million tons. Total container tonnage rose 1% to 24.22 million tons.

Vessel activity also increased. Port Houston recorded 710 vessel calls in July, up 4% from 684 in July 2025. Through the first seven months of the year, vessel calls totaled 5,054, a 7% increase from 4,723 a year earlier. Across the broader Houston Ship Channel, deep-draft transits rose 3% year over year in July to 1,523, and barge transits jumped 11% to 19,552. Through July, deep-draft traffic was up 7% and barge traffic increased 6%.

"Our region remains resilient through evolving global trade conditions. Vessel activity in the nation's busiest waterway is up, and we continue to see steady cargo movement that helps power industries like energy, manufacturing and retail, crucial to our national economy," Port Houston CEO Charlie Jenkins said in a statement.

The latest cargo figures come as a new economic impact study underscores the Houston Ship Channel's role in the national economy. Marine cargo activity through the public and private facilities along the channel supported $986.9 billion in annual U.S. economic value and nearly 3.53 million jobs in 2025, according to a study by Martin Associates released Tuesday.

In Texas, that activity supported $537.7 billion in annual economic value, equivalent to 18.5% of the state's gross domestic product, along with approximately 1.89 million jobs and $15.6 billion in state and local tax revenue. The study found the economic value supported by Houston-area maritime activity increased $98.4 billion between 2022 and 2025. Nationwide economic value increased 9% over that period, while the number of jobs supported nationally rose 5%.

The broader Houston Ship Channel region has also posted strong trade tonnage this year. Through June, total trade tonnage increased 16% year over year to 135.05 million tons, driven by a 22% increase in exports to 109.5 million tons. Imports declined 4% to 25.55 million tons.

The July slowdown reflects the fading effects of earlier import frontloading, but rising year-to-date container imports, vessel activity and general cargo volumes indicate that freight demand through the nation's largest port for waterborne tonnage remains resilient. Coming months will show whether container volumes settle back onto last year's pace or whether the year-to-date gains hold through the peak shipping season.
