01
Purity and method should lead the RFQ
Berberine HCL inquiries should state 97% or 98% purity target, HPLC requirement and acceptable batch document scope.
02
Application changes document expectations
Supplement, distributor and pharma-adjacent buyers may require different COA, MSDS, TDS and export review details.
03
MOQ and market help route suppliers
Sample, pilot and bulk quantities should be separated so the sourcing team can compare stock and fresh production routes.
