U.S. Port Imports to Decline as Extended Peak Season Ends

The National Retail Federation and Hackett Associates project that import volumes at major U.S. container ports will decline through the remainder of 2026 following an exceptionally strong extended peak season driven by tariff-related buying. September 2026 achieved 2.37 million TEU (the highest volume of 2026 and third-busiest month on record), but subsequent months are expected to show decreasing volumes as the surge ends. If projections hold, full-year 2026 will see a modest 2% increase over 2025 to reach 26 million TEU. The extended peak season reflects a structural shift in import behavior over the past two years.

Retailers have moved away from traditional pre-holiday stockpiling toward a just-in-case model, importing goods earlier than historically normal to hedge against supply chain disruptions and fluctuating tariff policies. The article details how tariff uncertainty, particularly mid-2026 increases, prompted importers to accelerate shipments through October, creating congestion at West Coast ports where cargo has faced extended waits for rail transfer. Supply chain professionals must prepare for a fundamental volatility shift. While current port congestion creates immediate operational challenges (particularly at Los Angeles/Long Beach, Oakland, and Tacoma), the forecast decline presents an equally important planning consideration.

Teams should assess inventory carrying costs, labor scheduling, and transportation contracts for the softer volumes ahead, while remaining vigilant about potential tariff policy changes that could trigger another surge. The economic backdrop of 3.4% GDP growth and sustained consumer spending suggests demand remains resilient, but the import deceleration signals retailers are satisfied with current in-stock positions after the extended buildup.
