Commercial terms

Volume commitments work best when they are structured as a rolling target rather than a single fixed number.
| Volume tier | Indicative unit level | Lead time |
|---|---|---|
| Carton (127 units) | Tier 1 | 30-45 days |
| Pallet (871 units) | Tier 2 | 21-30 days |
| Container (9965 units) | Tier 3 | 30-45 days |
