Recurring Supplier Defects: When to Reopen a Closed Claim
Reopen the review when new evidence indicates that a previously addressed defect may have returned. Link the new finding to the earlier case, verify the affected scope and reassess corrective-action effectiveness. Closing an earlier case does not itself establish a warranty or resolve a new claim.
Connect the new finding to the earlier record
Record the purchase order, SKU, specification revision, batch or lot, discovery date and inspection method. Preserve photographs, measurements and representative samples where practical. Link these to the earlier claim number and its agreed acceptance criteria.
Compare the symptoms and testing conditions before assigning a cause. Similar appearance does not prove the same root cause. Mark the cause as unconfirmed until the supplier and responsible quality team review the evidence.
Identify affected stock and containment decisions
List affected and potentially affected lots separately, including goods in production, transit and your warehouse. For stock under your control, identify and segregate suspect units as appropriate to the product and findings. Agree any supplier hold or additional inspection with the responsible parties and document the scope.
Do not extrapolate a small finding to every unit without a justified assessment. If the issue may involve product safety or mandatory reporting, involve the responsible product-safety and compliance specialists promptly; this operational checklist cannot determine those obligations.
Check implementation and effectiveness separately
Retrieve the earlier corrective-action record: proposed cause, agreed action, owner, completion evidence and follow-up checks. Ask what actually changed and which lots were produced after implementation. A completion signature alone does not show that the action prevented recurrence.
Compare the new evidence with the earlier effectiveness check. Determine whether the action was not implemented, was insufficient, or addressed a different cause. Record unresolved questions and assign a date and owner for each verification step.
Example: repeat symptom in a later lot
Illustrative example: three units fail the agreed fit check among 100 units examined from Lot B after a claim on Lot A was closed. Preserve the Lot B inspection record and specification revision, then request the change and inspection records associated with the earlier action.
Record three failures in the examined sample; do not present that observation as the defect rate for all shipments. The next decision might be an agreed expanded inspection, a bounded hold or further cause analysis, depending on the evidence and product requirements.
Document the new review and commercial outcome
Create a linked review entry rather than overwriting the original closure. State the affected scope, requested response, evidence still needed and next review date. Keep proposed replacement, rework or credit separate from an agreed remedy.
Review commercial rights, notice requirements and responsibility under the actual agreement with the relevant advisers when necessary. Reopening an internal review does not automatically create a refund entitlement. After resolution, verify the agreed action and monitor later lots before closing the new case; include recurring findings in the supplier performance review.
