Freight consolidation changes the answer to quality control process at container scale, which is why small and large buyers reach different conclusions.
Why quality control process matters on the Prime

Where two suppliers look identical on price, quality control process is usually the variable that separates them over a full year.
Functional testing of a sample from each batch is standard practice.

Commercial terms
Payment history is the single most reliable route to better terms, more than total annual volume.
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 (176 units) | Tier 1 | 30-45 days |
| Pallet (688 units) | Tier 2 | 14-21 days |
| Container (19271 units) | Tier 3 | 14-21 days |
