Comparing botanical extract supplier documentation? Check specification, COA, method notes, packing and export files before supplier approval.
Requirements
This B2B guide helps purchasing and QA teams prepare plant extract supplier questions before sending an RFQ. Use the Plant Extract COA Review Checklist 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 |
|---|---|---|
| Specification sheet | Ingredient name, source, extract ratio, marker, physical fields and storage. | The specification defines the buyer approval baseline. |
| Representative COA | Batch details, assay method, physical fields, microbiology and heavy metals. | The COA links sample review to supplier documentation. |
| Method note | HPLC, UV, TLC or buyer-specified method wording. | Method notes reduce confusion when comparing grades. |
| Packing documents | Packing size, label requirement, shelf-life or retest statement and export support. | Packing documents support logistics and QA review. |
| RFQ record | Quantity, MOQ expectation, lead time and destination market. | A complete RFQ record supports faster supplier response. |
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
Buyers usually review a specification sheet, representative COA, assay method note, packing information and export document support before quotation.
Different methods can describe the same material differently, so buyers should align method wording before comparing supplier documents.
Use the relevant product page or HERBSEA contact page with the specification target, sample needs, MOQ expectation and destination market.
Summary
If you are comparing plant extract suppliers, confirm the source, target specification, assay method, COA fields, sample test plan, MOQ, packing and destination market before quotation. A short document checklist keeps supplier comparison faster and easier to audit.
