When qualifying a commercial botanical extract manufacturer, formulation scientists and supply chain directors must evaluate four non-negotiable verification pillars to ensure active potency repeatability, compendial compliance, and chain of custody.
Verify whether assays are measured via HPLC/UHPLC vs non-specific UV/titration to eliminate matrix over-reporting.
Audit full compliance with USP <232> / ICH Q3D heavy metals, USP <467> Class 1–3 solvents, and USP <561> pesticides.
Demand lot-traceable Certificates of Analysis (COA), Technical Data Sheets (TDS), and Safety Data Sheets (SDS) for every delivery.
Establish verifiable chain-of-custody from botanical cultivation origin through extraction and packaging.
