Air Bar Diamond 4: Sample Order Workflow for Distributors
Published 2026 · VapeWholesaleHub trade desk

A disciplined sample workflow shortens the path from first interest to a Diamond 4 purchase order.
Between the factory gate and the retail shelf, sample order workflow is where most of the value on the Diamond 4 is either created or lost.
The most common mistake is optimising for the first order instead of the fourth, which is where Diamond 4 economics actually settle.
Why sample order workflow matters on the Diamond 4
Request samples with the final specification, not an approximation.
Retail staff rarely ask about sample order workflow directly, but their questions almost always lead back to it.
Evaluate across at least two weeks of real use.

Practical notes for buyers
Freight consolidation changes the answer to sample order workflow at container scale, which is why small and large buyers reach different conclusions.
