Freight consolidation changes the answer to airflow tuning at container scale, which is why small and large buyers reach different conclusions.

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

| Pallet (769 units) | Tier 2 | 30-45 days |
