Pharma Serialization and
Saleable Returns

Enter a pack's GTIN, serial, and lot, then its custody steps, each a party and an event type. This tool checks the GTIN's mod-10 checksum, walks the custody steps against the permitted commissioned, shipped, received, returned, decommissioned order, and tells you whether a returned pack's history is one it could actually have travelled rather than one that was typed in after the fact. A wholesaler deciding whether a returned pack can re-enter saleable stock needs that lineage, not a scanned barcode and a shrug.
