Published 2026 · VapeWholesaleHub trade desk
Quality control is where a Diamond Ultra order either protects or damages downstream relationships.
Distributors reviewing their Diamond Ultra range usually find that quality control process explains most of the variance in results between accounts.
Seasonality interacts with quality control process more than most forecasts allow for, so a rolling review beats an annual one.
Why quality control process matters on the Diamond Ultra
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 Diamond Ultra economics actually settle.
Functional testing of a sample from each batch is standard practice.
