Meaning
Legal provisions within the United Nations Convention on Contracts for the International Sale of Goods define the window of time and the substantive requirement for a buyer to notify a seller about non-conforming goods. cisg article 39 mandates that a notice specify the nature of the lack of conformity to allow the seller an opportunity to inspect or remedy the delivery. Failure to provide this notification within a reasonable time after discovery strips the buyer of the right to rely on the defect to claim damages or avoid the contract.
Notification Duty
Precise documentation of physical discrepancies between supplied polymer pellets and the agreed material specification is necessary to meet this requirement. Moulders detecting contaminated resins or deviations from the requested melt flow index must communicate these findings promptly to the resin supplier to preserve their legal recourse. Delays in testing materials upon receipt create a risk where the notification period expires before the production floor identifies the defect.
Tooling Latency
Injection moulding operations often encounter hidden faults in cavities or hot runner systems that only emerge after a production run reaches thermal equilibrium. Determining the reasonable time under cisg article 39 involves evaluating how quickly a skilled operator should have detected the issue through standard quality control checks. Technical personnel must balance the need for exhaustive batch analysis against the obligation to alert the supplier before the window closes.
Specification Breach
Discrepancies between a datasheet value and the performance of a resin under process conditions occasionally trigger disputes over whether a product conforms to the contract. Virgin materials might exhibit different viscosity characteristics than regrind blends, and the burden remains on the buyer to identify these variations as non-conforming early in the cycle. Proper application of these rules protects the integrity of the supply chain by forcing the early resolution of material quality conflicts.
