Buyers who treat serial number traceability as a commercial discipline rather than an afterthought tend to hold margin for longer.

Why serial number traceability matters on the Havana 2
Batch identifiers should appear on the unit, the inner tray and the master carton.

A simple spreadsheet linking batch to destination account is usually sufficient at this scale.
