Published 2026 · VapeWholesaleHub trade desk
Quality control is where a Zen 2 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 Zen 2.
In practice the decision comes down to three numbers: unit cost, freight per unit and the realistic sell through rate for Zen 2.
Why quality control process matters on the Zen 2
Incoming inspection sampling catches most issues before they reach shops.
Documentation is not paperwork for its own sake; on quality control process it is the difference between a clean clearance and a delayed one.
Functional testing of a sample from each batch is standard practice.
