How to Source Air Bar Zen 4: Minimum Order Quantity
Published 2026 · VapeWholesaleHub trade desk
Minimum order quantity is the first commercial filter in any Zen 4 sourcing conversation.
Across the trade, minimum order quantity is the point where good intentions meet operational reality on the Zen 4.
Documentation is not paperwork for its own sake; on minimum order quantity it is the difference between a clean clearance and a delayed one.
Why minimum order quantity matters on the Zen 4
The minimum usually applies per SKU rather than per order, which shapes flavour planning.
Retail staff rarely ask about minimum order quantity directly, but their questions almost always lead back to it.
Mixing flavours within one model is often allowed at carton level.

|---|---|---|
| Carton (167 units) | Tier 1 | 7-12 days |
| Pallet (1903 units) | Tier 2 | 30-45 days |
| Container (5050 units) | Tier 3 | 21-30 days |
