How to Source Air Bar Nex 4: Buyer FAQ

Published 2026 · VapeWholesaleHub trade desk

This buyer FAQ collects the questions distributors ask most often about Nex 4.

Buyers who treat buyer faq as a commercial discipline rather than an afterthought tend to hold margin for longer.

The most common mistake is optimising for the first order instead of the fourth, which is where Nex 4 economics actually settle.

Why buyer faq matters on the Nex 4

Commercial questions usually arrive before technical ones in any sourcing cycle.

In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Nex 4.

Clear answers early shorten the negotiation considerably.

Practical notes for buyers

Cash flow is the quiet constraint behind buyer faq: the cheapest option is rarely the one that frees the most working capital.

Where two suppliers look identical on price, buyer faq is usually the variable that separates them over a full year.

Checklist

Keep certificates current and filed against the exact model name.
Agree in advance who pays for return freight on a defect claim.
Verify that artwork matches the approved compliance template.
Record the arrival condition with photographs on the day of delivery.
Confirm the exact configuration in writing before the deposit is paid.
Check carton quantities against the commercial invoice line by line.

Commercial terms

Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.

Commercial terms are usually agreed in three parts: a deposit on confirmation, a balance before shipment and a stated validity window.

Volume tier	Indicative unit level	Lead time
Carton (74 units)	Tier 1	7-12 days
Pallet (1980 units)	Tier 2	30-45 days
Container (7070 units)	Tier 3	14-21 days

All figures above are indicative working ranges used for planning. Final specification and commercial terms are confirmed in writing before any deposit.
