Green tea extract sample requests need marker, COA and application details aligned before supplier comparison.
Green Tea Extract Sample Request Checklist
This checklist helps B2B sourcing, QA and formulation teams prepare a green tea extract sample request before quotation. The Green Tea Extract product page remains the main RFQ page for sample, specification, COA, packing, MOQ and quotation. This support page focuses on the information buyers should send so the supplier can route the request to the right grade and document package.
A sample request that only says green tea extract is usually too broad. Buyers should state the target marker, assay method, application format, sample quantity, COA needs, packing preference and destination market. These details reduce back-and-forth and help keep the sample, COA and quote connected.
Sample Request Fields to Prepare
| Field | What to send | Why it matters |
|---|---|---|
| Marker target | Catechins, tea polyphenols, EGCG direction or buyer-defined marker. | Routes the request to the right grade. |
| Assay method | HPLC, UV or buyer-specified method when available. | Supports COA and specification comparison. |
| Application | Capsule, tablet, powder blend, beverage or food project. | Connects sample testing with physical parameters. |
| Documents | Specification, representative COA, heavy metals section and questionnaire. | Helps QA review before bulk approval. |
| Sample quantity | Lab test amount, pilot amount or buyer-requested quantity. | Helps avoid under-sampling for application trials. |
| Commercial plan | MOQ expectation, packing preference, market and annual volume. | Supports a realistic quotation path. |
