Transport reliability beyond the freight rate

A low rate can hide an expensive outcome

A freight quotation describes a transport charge. A sourcing or delivery decision also needs to account for transit time, variability, handling, inventory and the actions needed when a shipment misses its promise. The cheapest quoted option may still be appropriate, but it should be assessed against that wider operating requirement.

Our interpretation of the research is to begin with a comparable lane and shipment population. A global freight headline is useful context; it cannot determine the economics of a specific customer flow.

Distance and delay tell different stories

UNCTAD’s 2025 maritime review describes how rerouting increased the distance travelled by cargo in 2024 faster than the growth in cargo volume. This illustrates how trade can keep moving while the journey becomes more demanding. It is historical global maritime evidence, not a reading of today’s rate or service on an individual lane. ^[1]

The World Bank’s LPI 2.0 methodology separates measures such as maritime connectivity and time spent in transshipment. Its tracking-based measures draw attention to distinct parts of the journey rather than treating logistics performance as one score. The underlying periods and country-level indicators differ from a carrier contract or a client delivery promise. ^[2]

Start with comparable shipment records

Define the origin, destination, mode, shipment type and promise that matter. Reconcile carrier milestones with the client’s actual receipt or delivery records. An arrival at port, release from customs and availability at a warehouse are different events.

Compare the typical journey with the difficult tail of outcomes. A median can describe the centre of performance while leaving important delays unexplained. Record missing milestones as evidence gaps rather than assuming that an absent update means an on-time movement.

Compare feasible options

An alternative route may change the number of handovers, clearance requirements, capacity availability or stock needed to protect service. A premium mode can be worthwhile for a defined exception without becoming the best default for every shipment.

Our proposed assessment compares like-for-like costs and service constraints. Test whether a delay originates with the carrier, a port, missing documentation, a supplier handover or the receiving process before changing the transport solution. Where attribution is unresolved, keep it unresolved in the decision record.

Questions for a lane review

• Which event defines on-time delivery, and has the promise definition stayed constant?
• Where do delays and missing updates concentrate?
• How do weight, volume, season and shipment mix affect the comparison?
• What inventory, handling and premium-freight consequences sit outside the quoted rate?
• Could the proposed alternative meet the required capacity and service in practice?

Make the trial accountable

Agree one change, a comparison method and service guardrails before introducing it. Review total cost per comparable shipment alongside delivery reliability and damage, rather than announcing a saving from the rate alone. Capture any additional planning or support effort.

A Transport Reliability Discovery Workshop can establish the lanes and records worth investigating. The subsequent diagnostic or trial would be separately scoped, with specialist freight or customs input where needed.
