One short form is all it takes. An engineer matches a lead sample plus comparison grades to your process and target metrics, and parcels are usually airborne within 1–3 working days.
Describe the application, the equipment it runs on and the numbers you need to hit. After a short review we pick a lead grade plus one or two comparison grades, so your lab can rank candidates side by side against the metrics that matter. Air dispatch normally follows within 1–3 working days.
How quickly a sample turns into an order depends on your market's registration rules, your qualification steps, real line conditions and what the trial data shows.
