Meaning
Administrative and engineering costs incurred when testing and certifying a product or component after a change in its design or manufacturing source ensure continued compliance with safety and performance standards. In long-term supply agreements, the re qualification overhead represents a significant cost barrier to switching suppliers.
Engineering Expense
Testing protocols require extensive laboratory time and documentation updates. This re qualification overhead includes both the direct test fees paid to third-party labs and the internal engineering hours devoted to verifying the modified component. These costs must be amortized over the lifetime of the product.
Supply Disruption
Switching to a cheaper component source can backfire if the associated testing processes take months to complete. During this transitional period, production may be halted, or older inventory must be used to prevent shortages. The re qualification overhead can exceed the initial savings of the cheaper component, making the change economically unviable.
Careful planning is required to synchronize component changes with scheduled product refreshes to minimize this financial burden.
Contractual Allocation
Supply agreements explicitly define which party bears the costs of mandatory testing when a change is initiated. If the supplier introduces a change for their own convenience, the contract typically obligates them to cover the re qualification overhead in its entirety. This clause protects the buyer from unexpected engineering bills caused by the supplier’s internal decisions.
