Batches that are distributed to both Great Britain and Northern Ireland must have a marketing authorisation that applies in Northern Ireland so the MA must be for UK-wide MA (PL) or a Northern Ireland only (PLNI). Packs with UK wide or NI only licenses must have the FMD safety features applied and the batch/pack data uploaded.

UK Parallel Imported packs are given a license designator PLPI on the list of published MHRA authorisations but the actual pack will have either a PL or PLGB license number printed on it.

CAP authorised medicines under the EMA Centralised Procedure can also be distributed to Northern Ireland; these packs must have the FMD safety features and their pack/batch data must be uploaded to the UKNI MVS where those packs are destined for NI.
