Read the FDA’s definition of the Traceability Lot Code and how and when it is created and used.
A traceability lot code means a descriptor, often alphanumeric, used to uniquely identify a traceability lot within the records of the traceability lot code source (defined below). This is similar to what industry currently refers to as a ‘lot’ or ‘lot code’.
Unless the relevant entity is exempt from the rule, the traceability lot code is assigned when the food is initially packed (for raw agricultural commodities not obtained from a fishing vessel), received by the first land-based receiver (for food obtained from a fishing vessel), or transformed. Once a TLC is assigned, it must stay the same as the food moves through the supply chain; it can only be changed if the food is transformed.
The traceability lot code (TLC) is an integral component of the rule’s requirements. It links to the other KDEs required, including the TLC Source, which provides the physical location where the traceability lot code for an FTL food was assigned.
