Air Bar Zen Pro Quality Control Process Checklist 2026

Published 2026 · VapeWholesaleHub trade desk

Quality control is where a Zen Pro order either protects or damages downstream relationships.

Distributors reviewing their Zen Pro range usually find that quality control process explains most of the variance in results between accounts.

Documentation is not paperwork for its own sake; on quality control process it is the difference between a clean clearance and a delayed one.

Why quality control process matters on the Zen Pro

Incoming inspection sampling catches most issues before they reach shops.

Where two suppliers look identical on price, quality control process is usually the variable that separates them over a full year.

Functional testing of a sample from each batch is standard practice.
