Material looks the same—some bonded, some general trade. Mixed storage and issue—handbook reconciliation fails at customs. Bonded and non-bonded are two identities: location, batch, ledger, and work-order issue all separate. Convenience mixing nurtures reconciliation accidents on the shelf.
Mixing saves one bin. Reconciliation loses a whole handbook.
Isolation in Three Layers
Physical zones or clear labels. System batches carry bonded flag; issue validates work-order nature. Returns go to original-attribute location. Inventory counts split handbook vs domestic books.
- Ban "use the similar-looking one first."
- Work orders cannot issue both attributes unless process and handbook allow with record.
- Variances adjust same day—don't pile to reconciliation season.

Identity Follows to Issue
The XYN digital intelligence system writes bonded attributes on batches and work orders—issue blocks mixing. Imported material can enter the plant—not confusion. Confusion's hotbed is that one unpartitioned slot.
Walk the bonded warehouse—any domestic material mixed in? Yes—isolate first, then talk next handbook balance.
