Inventory Replenishment Guide for Air Bar Diamond 4
Published 2026 · VapeWholesaleHub trade desk
Inventory replenishment discipline is what separates profitable Diamond 4 distribution from busy distribution.
Buyers who treat inventory replenishment as a commercial discipline rather than an afterthought tend to hold margin for longer.
Seasonality interacts with inventory replenishment more than most forecasts allow for, so a rolling review beats an annual one.
Why inventory replenishment matters on the Diamond 4
Reorder points should reflect lead time plus safety stock, not intuition.
Shops that receive a short briefing on inventory replenishment convert noticeably better than shops that only receive stock.
Fast movers deserve shorter review cycles than long tail flavours.

Commercial terms
Currency movement over a ninety day cycle can outweigh the difference between two competing quotations.
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.
| Volume tier | Indicative unit level | Lead time |
|---|---|---|
| Carton (152 units) | Tier 1 | 7-12 days |
| Pallet (1908 units) | Tier 2 | 30-45 days |
| Container (8322 units) | Tier 3 | 14-21 days |
