EMA updates batch-number guidance for parallel-traded medicinal products
EMA updated its GMP/GDP Q&A on 21 October 2026 concerning batch numbers on medicinal products relabelled or repacked for parallel trade. The Q&A states that applicable national legislation or guidance should be followed. Where none exists, the outer packaging should carry one batch number allocated by the parallel trader, ideally combining the original batch number with a unique repackaging or relabelling code. Traceability between original and additional numbers must be documented. If separate numbers are used, both must appear in recall information. A completely different parallel-trader batch number is strongly discouraged and requires justification and supervisory-authority authorisation.
