Published 2026 · VapeWholesaleHub trade desk
Quality control is where a Box 3 order either protects or damages downstream relationships.
Between the factory gate and the retail shelf, quality control process is where most of the value on the Box 3 is either created or lost.
The most common mistake is optimising for the first order instead of the fourth, which is where Box 3 economics actually settle.
Why quality control process matters on the Box 3
Incoming inspection sampling catches most issues before they reach shops.
Cash flow is the quiet constraint behind quality control process: the cheapest option is rarely the one that frees the most working capital.
Functional testing of a sample from each batch is standard practice.
