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.
Every serious sourcing conversation about the Diamond 4 eventually arrives at sample order workflow, usually because it is where cost and risk meet.
In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Diamond 4.
Why sample order workflow matters on the Diamond 4
Request samples with the final specification, not an approximation.
Cash flow is the quiet constraint behind sample order workflow: the cheapest option is rarely the one that frees the most working capital.
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.
