Commercial terms
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.
Freight terms should be named explicitly, because an unclear incoterm is the fastest way to lose a relationship.

| Carton (141 units) | Tier 1 | 30-45 days |
| Pallet (969 units) | Tier 2 | 21-30 days |
| Container (19313 units) | Tier 3 | 7-12 days |
