Generally you implement some other standard. In particular the global supply chain standard is GS1. Items have what is called a GTIN identifying their category specific to your company and serial numbers. GS1 likewise has an event called transformation. Your transformation event removes the bean from the chain and converts it to a packet. Just as converting a packet into case and a case into a pallet is an aggregation event. And then you have an aggregation event that does the reverse, converts the pallet back into cases.
The GS1 data standard also has a field for recording what items are part of these aggregations. So you can see that a pallet contains these cases with SN and GTIN's. Then when someone breaks the pallet down, and scans the cases, you have systems for recording this in the blockchain and then you can verify whether all of the cases that went into the pallet still existed when the pallet was broken down, and then packets in the case.
All of this data, its transformations, aggregations, and parent-child relationships are represented in simple standards like JSON and XML in GS1.
