Congestión portuaria en 2026: cómo proteger su cadena de suministro.

Global container port throughput reached record levels in late 2025 and early 2026, driven by a combination of recovered consumer demand, restocking cycles, and front-loaded shipments as importers sought to avoid anticipated tariff changes. This volume surge, combined with the knock-on effects of vessel reroutings following continued Red Sea tensions, has generated congestion at ports that were considered operationally clean as recently as mid-2024.

The pattern is uneven: some ports are handling volumes well, while others are under significant strain. Understanding which ports affect your lanes is the first step to routing around the worst delays.

The practical impact on shippers is a transit time uncertainty that makes traditional just-in-time inventory models risky. A shipment that nominally takes 28 days from Shenzhen to Rotterdam can arrive in 31–38 days under current conditions, with no reliable way to predict which end of that range applies to any given sailing.

For businesses that have tightened inventory to reduce working capital, this variability is costly: stockouts, expediting fees, and the premium of emergency air freight can far exceed the savings from running lean stock. The companies managing port congestion best in 2026 are those that have accepted a structural increase in their safety stock requirements and priced it into their models.

Port congestion is unlikely to resolve quickly. Structural factors — including fleet deployment patterns from the alliance reshuffles, the ongoing Red Sea routing detour, and sustained import demand — suggest elevated variability through at least Q3 2026. Shippers should plan accordingly, and engage their freight forwarder now to review routing and contingency options before the June–July peak season adds further pressure.
