Routing choices are shaping port performance

The next supply chain constraint may be your routing

As vessel capacity improves on some trade lanes, the factors influencing delivery performance are changing. Gateway selection, transshipment exposure, inland transportation connections, container availability and carrier network design are becoming more important determinants of reliability.

During periods of widespread congestion, securing space is often the primary challenge. Today, two deliveries moving between the same regions can experience very different outcomes depending on the gateways, inland transportation networks and carrier services supporting the move.

The result is a market where routing decisions matter more than they did earlier in the year. A lower-cost option may involve additional transshipping or weaker inland connectivity, while a different routing may offer more predictable transit performance despite similar market conditions.

Shipper impact: As ocean capacity improves, delivery performance is increasingly determined by the strength of the transportation network supporting the move, not simply the availability of vessel space.

Gateway performance is becoming easier to distinguish

South America provides a clear example of how gateway performance is becoming a more important differentiator.

Congestion at the Port of Manzanillo in Mexico and Rodman Port in Panama continues to create missed connections, cargo rollovers and schedule variability across portions of the Pacific network. Elsewhere in the region, Cartagena continues strengthening its position as a preferred Caribbean hub in Colombia, while Peru's Chancay is emerging as a more strategic Pacific gateway as carriers expand services. In Colombia, Puerto Antioquia is also preparing to introduce another direct option for import cargo.

The contrast highlights an opportunity for shippers to evaluate routing options. Carrier investment, service design and network connectivity are creating advantages in some locations while persistent bottlenecks continue to affect others.

Shipper impact: Selecting the right gateway may have a greater effect on transit consistency than small differences in ocean transportation costs.

Inland transportation networks are increasingly determining cargo velocity

Choosing the right gateway is only part of the equation.

In Canada, rail networks that carry ocean freight continue recovering from wildfire disruptions. Draft restrictions on the Panama Canal continue influencing vessel deployment and routing decisions. In Europe, low water levels on the Rhine River remain a factor for cargo moving to and from north European ports. In these cases, it’s the broader transportation network affecting the ports.

These conditions reinforce a reality that many shippers are confronting this year: Cargo velocity is increasingly determined by the connections between transportation modes, not just the performance of a single port, rail provider or carrier.

Shipper impact: Ports may appear stable, but freight velocity can still deteriorate when inland networks slow.

Container availability remains an operational constraint

In North America, rail-related delays and longer container dwell times continue to affect equipment positioning. On the Indian Subcontinent, container shortages remain a challenge at some inland locations. In both markets, equipment availability can affect routing flexibility long before cargo reaches the port.

As capacity pressures ease on some trade lanes, limited containers can still delay deliveries, force routing changes, increase handling requirements or reduce schedule reliability even when vessel space is available.

Delivering success increasingly depends on the combination of gateways, inland networks, carrier services and equipment supporting a delivery. Taken together, these developments point to a market that is more selectively than universally constrained.

Shipper impact: Container access may become a limiting factor even when vessel space is readily available.

What shippers can do

• Look beyond vessel space. Gateway selection, transshipping and inland connectivity can have a meaningful impact on transit performance.
• Monitor localised constraints. Congestion at key transshipment hubs, Canadian rail recovery, Panama Canal draft restrictions and Rhine River water levels continue affecting specific transportation corridors.
• Reassess routing options. Carrier network changes and emerging gateways may create alternatives that reduce exposure to bottlenecks and improve supply chain resilience.
• Plan container needs early.
• Evaluate transportation networks end to end. Inland performance is increasingly influencing ocean delivery reliability.

Notable shifts this month

Canada: Rail recovery efforts continue

Rail service has resumed on key wildfire-affected corridors, but Canadian networks are still working through backlogs, railcar shortages and residual congestion.

Elevated dwell times and slower cargo velocity are expected to remain a consideration in the weeks ahead as railroads restore network fluidity and clear accumulated freight volumes.

Shipper impact: Inland transportation performance may recover more slowly than port operations, making lead-time assumptions worth re-evaluating.

Panama Canal: Water levels continue affecting routing decisions

The Panama Canal remains operational, but draft restrictions continue influencing vessel deployment and cargo allocation on some East Coast and Gulf Coast services. Some ocean carriers have implemented weight limitations on cargo and announced surcharges on affected services.

Carriers are expected to maintain routing and capacity strategies designed around those constraints, limiting flexibility on certain trades.

Shipper impact: Service design, vessel deployment decisions, cargo weight allowances and surcharges may continue to reflect canal restrictions even where customer demand remains stable.

Europe: Rhine River conditions remain a constraint for inland freight

Low Rhine River water levels continue affecting cargo movements between inland European manufacturing regions and north European ports.

Shippers relying on barge transportation may continue facing operating restrictions, reduced efficiency and the need for additional planning flexibility if conditions persist through the coming weeks.

Shipper impact: Even where ocean services are performing normally, inland transportation constraints can still affect delivery timing.

Indian Subcontinent: Space remains tight despite easing conditions elsewhere

While capacity has improved in parts of the global market, the Indian Subcontinent remains one of the most constrained origins.

Limited vessel allocations, equipment shortages at inland locations, carrier capacity control and recent service changes continue putting pressure on exports bound for North America and Europe.

Early booking and accurate forecasting are expected to remain important throughout the peak-season period.

Shipper impact: Equipment availability, allocation controls and inland execution remain important planning variables despite broader improvements in global capacity.

How shippers can prepare for the month ahead

• Evaluate routing options holistically. Consider transshipment exposure, inland connectivity, equipment availability and network resilience, not just ocean freight rates.
• Monitor transportation corridors individually. Rail recovery efforts, water-level restrictions and inland transportation disruptions continue influencing specific regions even as broader market conditions stabilise.
• Review emerging gateway opportunities. New service structures and developing gateway options may help to reduce bottlenecks, shorten inland moves or improve routing flexibility.
• Build flexibility into delivery planning. Equipment shortages, localised congestion and allocation constraints remain factors in selected regions and may require additional lead time.
• Focus on end-to-end network performance. Cargo velocity is increasingly influenced by the connections between ports, inland transportation providers, equipment pools and carrier services.
• Prioritise execution reliability alongside cost. The lowest-cost routing may not always provide the most consistent delivery performance.
