Published 2026 · VapeWholesaleHub trade desk
Quality control is where a Zen S order either protects or damages downstream relationships.
There is no shortcut on quality control process: the Zen S rewards preparation and punishes improvisation.
In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Zen S.
Why quality control process matters on the Zen S
Incoming inspection sampling catches most issues before they reach shops.
Shops that receive a short briefing on quality control process convert noticeably better than shops that only receive stock.
Functional testing of a sample from each batch is standard practice.
