Commercial terms
Most long running accounts settle into a rhythm of monthly top ups with one larger seasonal build per year.
Volume commitments work best when they are structured as a rolling target rather than a single fixed number.
| Volume tier | Indicative unit level | Lead time |
|---|---|---|
| Carton (184 units) | Tier 1 | 14-21 days |
| Pallet (1330 units) | Tier 2 | 14-21 days |
| Container (14083 units) | Tier 3 | 30-45 days |
Frequently asked questions
How many Zen 4 samples should we request?
Three to five units per shortlisted configuration is enough to judge consistency.
Can several models be mixed in one shipment?
Yes, mixing models and flavours within a carton or pallet is common and usually helps first time buyers test demand.
Is documentation provided for customs?
Commercial invoice, packing list and the relevant certificates are supplied; the importer's broker handles the declaration.
Do you support long term supply agreements?
Yes, rolling agreements with defined review points work better for both sides than rigid annual commitments.
Final word
Start with one change, measure it over a quarter, then decide whether it deserves to become policy.
