A procurement checklist for comparing botanical extract suppliers on evidence, consistency and traceability.
Price is the easiest number to compare and often the least informative one. A cheaper extract with incomplete evidence can cost more later through reformulation, release delays or regulatory work.

Documentation completeness: confirm the current status of the CoA, TDS, SDS and application-specific records.
Traceability: ask whether the supplier can identify raw-material origin at lot level.
Batch consistency: compare marker values and analytical methods across more than one batch where data is available.
Legal origin and trade controls: check the exact botanical species and the records required for that species and shipment. CITES applies only to listed species.
