What to Check in an Ashwagandha Extract COA PURCHASING TEMPLATE — not a supplier-issued document Please provide the proposed ashwagandha extract specification and a legible COA. Confirm botanical identity, plant part, grade, lot number and document date. For the withanolide assay, identify the included analytes, method, units and reporting basis. Confirm which identity, microbiological, contaminant and residual-solvent records apply. Identify any missing tests and whether supporting reports can be requested. Confirm whether the sample and proposed shipment belong to the COA lot. If no shipment lot is selected, label reference documents accordingly and supply lot-matched records before acceptance.
