"A Backup Supplier Can Still Depend on the Same Shipping Route"
A second supplier can reduce dependence on one factory while leaving a manufacturer exposed to the same transport disruption. If both sources rely on the same canal, gateway or inland connection, the purchasing team may have diversified its contracts without creating another way to reach production. That distinction is easy to miss when supplier selection and transport planning are assessed separately. A sourcing decision can look resilient on paper while the delivery plan still contains a single point of failure.
The issue becomes more pressing when cargo changes route after an order has been awarded. A supplier’s original price and promised delivery date may reflect a journey that is no longer available on the same terms. The shipment then needs a workable alternative through ports, inland transport and factory receiving schedules. Comments from Coupa and material supplied by C.H. Robinson point to the need to evaluate those connections before a disruption forces a purchasing decision.
The Factory Deadline Does Not Move With the Container
Nari Viswanathan, Head of Product Marketing and Solutions for Supply Chain and Direct Spend at Coupa, argues that a change in shipping route should trigger a review of the assumptions behind the sourcing award. His response to The Supply Chainer focuses on the difference between securing another supplier and securing another deliverable route. An alternative part price has limited meaning until the buyer understands how that part will reach the plant. Viswanathan said: “For production-critical components, procurement should compare the full path from each supplier to the plant. If the primary and backup suppliers both depend on the canal, a second contract offers little protection from a transit delay. Another qualified supplier may cost more per part but deliver through Los Angeles with a workable inland connection. If that connection is uncertain, keeping a small amount of stock near the plant may be the more reliable choice.
“The next sourcing award should make those trade-offs clear before a shipment is diverted: which supplier has another route, how quickly can the part reach production and what would a delay cost?”
The choices he describes address different causes of delay. A qualified alternative supplier can change the origin of the goods, while a different transport route changes how they travel. Stock near the factory provides time to respond when either arrangement fails. These options need to be compared against the production requirement, because a cheaper component that arrives after it is needed can create costs beyond the purchasing budget.
A Different Port Introduces Another Capacity Question
C.H. Robinson responded to the diesel-price inquiry by directing The Supply Chainer to its October Edge Report. The accompanying report summary places trucking capacity, fuel costs, ocean freight planning and port congestion within the same operating picture. Its freight-market section describes how trucking conditions are increasing demand for less-than-truckload and intermodal services. It also identifies post-Golden Week demand and port congestion as factors influencing ocean freight planning.
The company’s summary states: “This month’s edition looks at the trends in freight markets and supply chains as 2026 enters its final quarter. From tightening trucking capacity and record diesel prices to changing trade relationships and cross-border complexity, the report examines the developments shaping transportation strategies and costs.”
That is a company assessment of market conditions, rather than evidence that a particular alternative route has capacity available. For a buyer considering a different gateway, the remaining questions concern the shipment itself: the inland service, transfer arrangements, receiving window and expected delivery date. A port substitution changes those dependencies. It does not establish that the onward journey can absorb the additional freight.
Price the Alternative Before It Becomes Urgent
Earlier Supply Chainer reporting connected supplier selection with operational recovery in another context. Discussing cybersecurity, Ben Leiken, Chief Technology Officer at Arkestro, said: “Supplier security posture is now a sourcing decision, not just an IT one.” His comments concerned disruption originating at suppliers rather than shipping routes. The relevant connection is that procurement needs to evaluate whether an alternative can actually be put into operation when the original arrangement fails.
For transport-dependent sourcing, that evaluation should make shared dependencies visible. Two suppliers may use different factories but rely on the same export gateway, and two shipping services may ultimately require the same inland transfer. Identifying that overlap allows the buyer to assess an alternative on its practical contribution to continuity. The useful comparison includes the additional purchase or transport cost, the time needed to activate the option and the consequences of waiting.
Viswanathan’s response leaves procurement with a concrete test for the next award: can the alternative deliver the required component when the primary route cannot? The answer may favour another qualified supplier, a different connection or a limited inventory buffer. Each has a cost that can be assessed before the shipment becomes urgent. A second contract earns its place in a resilience plan when it provides a usable option for keeping production supplied.
