How to Source Air Bar Diamond 3: Sample Order Workflow
Published 2026 · VapeWholesaleHub trade desk
A disciplined sample workflow shortens the path from first interest to a Diamond 3 purchase order.
Between the factory gate and the retail shelf, sample order workflow is where most of the value on the Diamond 3 is either created or lost.
Keeping a short internal note on sample order workflow for each SKU pays for itself the first time a dispute arises over the Diamond 3.
Why sample order workflow matters on the Diamond 3
Request samples with the final specification, not an approximation.
The most common mistake is optimising for the first order instead of the fourth, which is where Diamond 3 economics actually settle.
Evaluate across at least two weeks of real use.

Practical notes for buyers
Cash flow is the quiet constraint behind sample order workflow: the cheapest option is rarely the one that frees the most working capital.
Consistency across batches matters more than peak performance for Diamond 3, and sample order workflow is where inconsistency first appears.
Checklist
- Retain one sealed sample carton from every batch for reference.
- Request batch photographs and a packing list prior to shipment.
- Agree in advance who pays for return freight on a defect claim.
- Keep certificates current and filed against the exact model name.
- Check carton quantities against the commercial invoice line by line.
- Log sell through by account for the first eight weeks.
Commercial terms
Payment history is the single most reliable route to better terms, more than total annual volume.
Most long running accounts settle into a rhythm of monthly top ups with one larger seasonal build per year.
