Requesting plant extract samples from suppliers? Prepare application, target specification, sample quantity, COA and packing needs in one RFQ.
Requirements
This B2B guide helps purchasing and QA teams prepare plant extract supplier questions before sending an RFQ. Use the Plant Extract Supplier hub as the main working path, then confirm specification, COA, sample and commercial details with the supplier.
For faster supplier review, prepare the botanical source, target marker or extract ratio, assay method, sample quantity, document list, MOQ expectation, packing size and destination market in one request.
Selection Criteria
| Review point | What to confirm | Why it matters |
|---|---|---|
| Application | Capsule, tablet, powder blend, beverage, food or cosmetic ingredient project. | Application affects particle size, color, odor and document needs. |
| Specification target | Marker, extract ratio, assay method, source direction and physical fields. | Specific targets reduce generic sample replies. |
| Sample quantity | Testing amount, number of grades and destination address. | Suppliers need this to plan available sample lots. |
| Document set | Specification sheet, representative COA, method note and export documents. | Documents help QA screen samples before internal testing. |
| Next RFQ step | MOQ, packing size, lead time and destination market. | These fields support the quotation after sample review. |
Practical Recommendation
Use a product page when the grade is already clear. Use this guide when the buyer still needs to compare assay methods, sample approval steps, documentation scope or commercial terms across multiple botanical extracts.
Sample Review vs Bulk RFQ
| Dimension | Sample review | Bulk RFQ |
|---|---|---|
| Main purpose | Confirm grade fit, documents and physical behavior. | Confirm supply, packing, lead time and export needs. |
| Buyer input | Application, target marker, sample quantity and document list. | Quantity, MOQ expectation, packing size and destination market. |
| Limit | Does not prove commercial availability without RFQ details. | Should follow sample or document approval when specifications are strict. |

FAQ
Include application, target specification, sample quantity, COA needs, destination address, MOQ expectation, packing size and follow-up RFQ timing.
Yes. A representative COA and specification sheet help QA connect the sample lot with supplier claims and buyer requirements.
Use the same test conditions and compare specification, COA, physical behavior, document completeness and commercial terms.
Summary
