Commercial terms
Volume commitments work best when they are structured as a rolling target rather than a single fixed number.
Freight terms should be named explicitly, because an unclear incoterm is the fastest way to lose a relationship.

| Pallet (1887 units) | Tier 2 | 14-21 days |
| Container (10091 units) | Tier 3 | 7-12 days |
