Buyer Decision Guide
A 4:1 ratio extract, tea-polyphenol standardised powder and L-theanine grade are not equivalent. Match the assay, method, sensory requirements and current batch COA to the formulation.
- Shortlist the required product form and target specification.
- Compare the current COA method, limits and batch results.
- Test the sample in the intended formulation.
- Approve the order specification, packing and destination-market documentation.

Frequently Asked Questions
How do I choose a green tea extract powder grade?
A 4:1 ratio extract, tea-polyphenol standardised powder and L-theanine grade are not equivalent. Match the assay, method, sensory requirements and current batch COA to the formulation.
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.
