Frequently Asked Questions
How do I choose a ashwagandha extract powder grade?
Choose between a ratio extract and an assay-standardised grade. Compare botanical identity, plant part, analytical method and withanolide target before approving a sample.
Can I compare the current batch COAs before ordering?
Yes. Request the applicable current or representative COA for each shortlisted grade and compare product identity, method, limits and results.
Are different ratios or assay percentages interchangeable?
No. Ratio extracts and standardised assay grades represent different purchasing specifications and should be qualified separately.
Can I request samples for formulation testing?
Yes. Provide the target grade, application, destination market and expected volume so sample availability can be confirmed.
What should be included in a quotation request?
Send the product grade, analytical limits, quantity, packing, destination, application and any required compliance documents.
Does website information replace the shipment COA?
No. The approved order specification and shipment-batch COA remain the controlling quality records.
Can specifications or packaging be customised?
Selected analytical limits, particle properties and packing may be reviewed case by case before quotation.
