Air Bar Diamond Quality Control Process Explained
Published 2026 · VapeWholesaleHub trade desk
Quality control is where a Diamond order either protects or damages downstream relationships.
A range review that ignores quality control process will often produce a confident decision and a disappointing quarter on the Diamond.
Shops that receive a short briefing on quality control process convert noticeably better than shops that only receive stock.
Why quality control process matters on the Diamond
Incoming inspection sampling catches most issues before they reach shops.
Seasonality interacts with quality control process more than most forecasts allow for, so a rolling review beats an annual one.
Functional testing of a sample from each batch is standard practice.

Commercial terms
Payment history is the single most reliable route to better terms, more than total annual volume.
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.

|---|---|---|
| Carton (147 units) | Tier 1 | 14-21 days |
| Pallet (581 units) | Tier 2 | 7-12 days |
| Container (10074 units) | Tier 3 | 7-12 days |
