Commercial terms

Most long running accounts settle into a rhythm of monthly top ups with one larger seasonal build per year.

|---|---|---|
| Carton (91 units) | Tier 1 | 14-21 days |
| Pallet (1736 units) | Tier 2 | 14-21 days |
| Container (8201 units) | Tier 3 | 30-45 days |
Frequently asked questions
How many Smooth 4 samples should we request?
