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 (66 units) | Tier 1 | 21-30 days |
| Pallet (988 units) | Tier 2 | 14-21 days |
| Container (7569 units) | Tier 3 | 14-21 days |
