Quality Control Process Guide for Air Bar Zen
Published 2026 · VapeWholesaleHub trade desk
Quality control is where a Zen order either protects or damages downstream relationships.
Distributors reviewing their Zen range usually find that quality control process explains most of the variance in results between accounts.
Where two suppliers look identical on price, quality control process is usually the variable that separates them over a full year.
Why quality control process matters on the Zen
Incoming inspection sampling catches most issues before they reach shops.
The most common mistake is optimising for the first order instead of the fourth, which is where Zen economics actually settle.
Functional testing of a sample from each batch is standard practice.

| Pallet (1223 units) | Tier 2 | 14-21 days |
