How to Source Air Bar Nex 4: Sample Order Workflow
Published 2026 · VapeWholesaleHub trade desk
A disciplined sample workflow shortens the path from first interest to a Nex 4 purchase order.
The Nex 4 has settled into a stable position in the range, which makes sample order workflow the natural next question for distributors.
The most common mistake is optimising for the first order instead of the fourth, which is where Nex 4 economics actually settle.
Why sample order workflow matters on the Nex 4
Request samples with the final specification, not an approximation.
Documentation is not paperwork for its own sake; on sample order workflow it is the difference between a clean clearance and a delayed one.
Evaluate across at least two weeks of real use.

Commercial terms
Commercial terms are usually agreed in three parts: a deposit on confirmation, a balance before shipment and a stated validity window.
Payment history is the single most reliable route to better terms, more than total annual volume.
