BUYER FAQ
Questions before qualification
What defines a standardized extract?
A standardized extract states a target marker or active level together with its analytical method and acceptance limits.
Can equal percentages be compared directly?
Only when botanical source, plant part, analyte, unit and analytical method are also equivalent.
What should be approved before purchase?
Approve the exact specification, sample where required, and the current offered-lot COA rather than relying on the product name alone.
