Systems and methods are provided for associating traceability codes on clamshells with unique identifiers on containers in which the empty clamshells are packed for later use. In various methods, the clamshells are marked with traceability codes and stacked together, one traceability code is read from one of the clamshells in each stack, a unique identifier is read from a container, and the stack is placed in the container. The traceability code is stored in association with the unique identifier for later retrieval. An exemplary table for making clamshell-to-container associations comprises a scanner for reading traceability codes and rails for positioning stacks of clamshells proximate to the scanner. The table can also comprise a second scanner positioned to read unique identifiers from containers placed proximate thereto. The table can further comprise a computing system to make and store the associations.
