Commercial terms
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.
Most long running accounts settle into a rhythm of monthly top ups with one larger seasonal build per year.
| Volume tier | Indicative unit level | Lead time |
|---|---|---|
| Carton (170 units) | Tier 1 | 30-45 days |
| Pallet (842 units) | Tier 2 | 21-30 days |
| Container (7700 units) | Tier 3 | 21-30 days |
