August Container Imports Hit 2.3M TEUs, Peak Season Ends Early

When did container import volumes peak in 2026?

August was the busiest month for U.S. container imports in 2026, with ports handling 2.3 million twenty-foot equivalent units. That replaced September as the anticipated peak and marks the end of an unusually long stretch of elevated volumes that began in early summer, according to the National Retail Federation's Global Port Tracker report.

The August figure was up 0.4% from July but down 0.7% from August 2025. September imports are now forecast at 2.28 million TEUs, down from an earlier projection of 2.31 million, though still up 8.2% year over year. October is expected to bring 2.25 million TEUs, up 8.5% from 2025, before volumes drop to 2 million TEUs in November.

"Even with any fluctuations in final data, we're likely past the busiest part of the year," said Jonathan Gold, NRF's vice president for supply chain and customs policy. "The truth is that the peak season started early and was stretched out through the summer and early fall, with the difference from month to month often amounting to little more than a rounding error."

What the early peak means for domestic freight

The shift matters for truckload carriers because container imports drive drayage volumes and, downstream, domestic distribution runs. An early peak followed by a gradual decline through year-end suggests the seasonal surge in short-haul and last-mile freight tied to holiday merchandise has already passed. Gold said most holiday goods have already arrived, with "last-minute replenishment and preparation for early 2027" driving the balance of 2026 shipments.

That aligns with what small fleets have seen on tender lead times and rejection rates through late summer. If retailers front-loaded inventory earlier than usual, the typical September-October freight spike flattens, and carriers face a longer tail of lower-volume weeks heading into Thanksgiving.

Ben Hackett, founder of Hackett Associates, said imports have been bolstered by robust consumer spending despite weakening economic indicators, declining consumer confidence, and increasing inflation. That disconnect between consumer behavior and sentiment has kept volumes elevated longer than the economic data alone would predict.

Volume outlook through November

The NRF projects full-year imports at the ports covered by the report will reach 25.8 million TEUs, up 1.4% from 2025. September and October volumes are expected to remain above year-earlier levels despite the month-to-month decline from August's peak. November's forecast of 2 million TEUs would represent the first significant step down.

The gradual retreat rather than an abrupt drop means drayage and regional distribution freight won't fall off a cliff, but the incremental decline week to week will show up in spot availability and rate pressure for carriers working port markets and retail lanes. Fleets that rely on import-driven freight should plan for tighter margins through the fourth quarter as shippers shift from stocking mode to replenishment.

Why this matters for small fleets

An early peak and extended shoulder season change the timing of when freight tightens and when it loosens. For owner-operators and small fleets working Southern California, the Pacific Northwest, or East Coast port markets, the August peak means the highest-volume weeks are already in the rearview. The September and October forecasts, while still up year over year, won't match the intensity of late summer.

That has implications for spot rates in port-to-warehouse lanes and for how aggressively shippers will bid for capacity in the final two months of the year. If most holiday merchandise has already cleared the docks, the remaining freight is lower-urgency replenishment, which typically commands lower rates and longer lead times. Fleets that didn't lock in contract rates during the summer peak may find themselves competing for thinner margins as November approaches.
