US FDA
21 CFR 211.125 - Labeling Reconciliation
Plain-language explanation, inspection context and common violation patterns.
What it says
Labels issued for a batch must be reconciled at the end of the packaging operation, with quantities of labels issued, used, damaged and returned accounted for, and any discrepancy beyond an established limit must be investigated.
Paraphrased for plain-language clarity. Always verify against the current published regulation text.
What it means in practice
- Reconciliation is a specific, quantitative check performed at the end of every packaging run, not a general assurance that labeling controls exist somewhere in the system.
- A discrepancy outside the approved tolerance is a required investigation trigger in its own right, independent of whether any specific mislabeled unit has actually been identified.
- The reconciliation record itself becomes part of the batch documentation demonstrating labeling control was verified for that specific batch, not just for the labeling system generally.
What FDA inspectors look for
- Whether label reconciliation is performed and documented for every packaging batch, with the actual numeric accounting visible in the batch record.
- Whether discrepancies beyond the established tolerance are genuinely investigated, rather than the tolerance itself being adjusted after the fact to avoid triggering investigation.
- Whether reconciliation covers all categories, issued, used, damaged and returned labels, rather than only tracking labels actually applied.
Most common violation
Label reconciliation discrepancies outside the approved tolerance closed without documented investigation, or tolerances set loosely enough that genuine mix-up risk would not reliably trigger a discrepancy flag.
