Market Updates
Retrospective market updates are not possible.
If an OBP needs to modify the list of target markets, a new version of the product code must be created with the correct market list.
⚠️ Important:
A batch can only be linked to one version of a product code.
Batches already associated with a previous version cannot be reassigned to a new version.
IMT’s Role
The Inter-Market Transaction (IMT) process ensures smooth cross-market distribution:
If a national system does not recognize a pack, it issues an IMT request via the EU Hub.
The EU Hub relays the request to the market that holds the relevant pack data.
That market then responds for verification or state change.
➡️ This ensures that distribution and serialization across markets remain seamless, compliant, and aligned with EU-wide regulations, even when markets differ in their data holdings.
