Across the trade, serial number traceability is the point where good intentions meet operational reality on the Diamond 4.

Why serial number traceability matters on the Diamond 4
Batch identifiers should appear on the unit, the inner tray and the master carton.

Commercial terms
Most long running accounts settle into a rhythm of monthly top ups with one larger seasonal build per year.
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.

|---|---|---|
| Carton (116 units) | Tier 1 | 7-12 days |
| Pallet (1763 units) | Tier 2 | 21-30 days |
| Container (5447 units) | Tier 3 | 21-30 days |
