Commercial terms
Volume commitments work best when they are structured as a rolling target rather than a single fixed number.
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 (141 units) | Tier 1 | 30-45 days |
| Pallet (1427 units) | Tier 2 | 7-12 days |
| Container (15018 units) | Tier 3 | 30-45 days |
Frequently asked questions
How can leakage in Crown Ultra shipments be reduced?
Use sealed inner trays, keep cartons upright and allow a settling period before retail display.
Do you support long term supply agreements?

How quickly can a repeat order be produced?
For established configurations production typically runs two to four weeks, with transit on top depending on the chosen method.
