Port Constraints Persist Despite Slowing Imports: C.H. Robinson

C.H. Robinson's November 2026 Edge Report reveals that U.S. container ports continue experiencing significant inland transportation constraints despite moderating import volumes. The logistics company warns that lower container demand will not automatically resolve capacity issues, as uneven vessel arrivals and elevated dwell times continue straining equipment availability and terminal access. Key trouble spots include Southern California, where rail-bound containers average 7.19 days at marine terminals versus 3.18 days for truck-bound shipments, Savannah's ongoing chassis shortage, Houston's congestion-driven cost pressures, and Norfolk's reduced terminal access windows.

These operational headwinds have critical implications for supply chain planning and cost management. Extended equipment cycles, reduced terminal flexibility, and limited railcar availability are compressing margins and extending delivery timelines even during periods of declining import activity. The report emphasizes that seasonal relief traditionally expected during demand slowdowns may not materialize, forcing shippers and carriers to maintain elevated contingency buffers. Additionally, the gradual return of container services through the Suez Canal creates the risk of temporary congestion at European terminals when overlapping arrivals from competing routes converge.

Supply chain professionals should reassess terminal access strategies, chassis positioning policies, and inland delivery schedules rather than assuming improved port conditions will follow demand reduction. Proactive engagement with terminal operators and drayage providers, combined with realistic planning for extended dwell times, will be essential to managing costs and service levels through the remainder of 2026.
