Commercial terms
Commercial terms are usually agreed in three parts: a deposit on confirmation, a balance before shipment and a stated validity window.
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.
| Volume tier | Indicative unit level | Lead time |
|---|---|---|
| Carton (177 units) | Tier 1 | 7-12 days |
| Pallet (1219 units) | Tier 2 | 21-30 days |
| Container (15676 units) | Tier 3 | 14-21 days |
