Split and merge events in identity
Splitting a lot or merging lots creates new identities. This guide covers how those events are recorded so no quantity appears twice or disappears..
Traceability shows movement and custody. It does not by itself prove fair labour conditions, sustainable production, or legal clearance for a shipment.
