Commercial terms
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.
Agreeing a defect handling procedure before the first shipment removes emotion from later conversations.
| Volume tier | Indicative unit level | Lead time |
|---|---|---|
| Carton (116 units) | Tier 1 | 21-30 days |
| Pallet (827 units) | Tier 2 | 14-21 days |
| Container (13677 units) | Tier 3 | 30-45 days |
