Product forms for your application
Our quotation range covers the material forms below. We confirm the available grade, concentration and sample terms in your quotation.
On small screens, scroll within the table.
| Form | Composition | Application fit |
|---|---|---|
| Broad seed extract | Seed-derived polyphenol mixture | Botanical dry blends |
| Proanthocyanidin-enriched fraction | Oligomer/polymer definition and method declared | Assay-led ingredient projects |
| Carrier-containing powder | Native extract and drying carrier distinguished | Handling and dispersion development |
Specifications, assay methods & quotation basis
| Item | Quotation & acceptance basis |
|---|---|
| Identity & composition | Vitis vinifera · seed extract · State ingredient composition, source route, carriers and relevant processing aids. |
| Markers & methods | OPC needs a degree-of-polymerization definition, method and reference standard. Total phenolics, colour reactions and chromatographic oligomer fractions are not interchangeable. |
| Physical & handling properties | Agree colour, odour, moisture, particle size and dissolution or dispersion requirements for the selected form, rather than one limit for every grade. |
| Contaminants & release | Agree microbiological, pesticide, elemental-impurity and residual-solvent scope and limits by source, process and market. Batch COA values must correspond to actual results. |
Why buy grape seed extract from ZL Botanicals?
Competitive bulk pricing
Match your ingredient budget to the selected assay, form and order volume, with commercial terms set out in one quotation.
Quality for repeat purchasing
Seed identity, a defined assay method and agreed acceptance criteria give QA and production a practical basis for lot review.
Certification-document support
Get support with the technical and certification documentation relevant to your selected material and destination market.
Reliable delivery coordination
Coordinate samples, commercial quantities and replenishment around your production schedule, with shipping arrangements confirmed for the order.
Quality control, COA & certification documents
Chromatographic identity and adulteration risk controls matter alongside assay. Include seed traceability, extraction solvent and relevant allergen declarations.
TDS defines the specification, COA records the identified batch, and SDS supports safe handling. We coordinate documents for the project and review certification needs against material, holder, site, scope and validity. Include GMP, ISO, Halal, Kosher or organic requirements in the enquiry; these are not blanket certifications for every product.
Application formats & sample evaluation
Astringency and protein interactions matter in drinks; colour and oxidation matter in a serum. Assess the offered sample in the full formula rather than transferring a laboratory antioxidant result.
These are development concepts, not customer cases, validated formulas or finished-goods manufacturing offers. Confirm intended use for the material and target market.

Request pricing by volume & destination →Grape Seed Extract purchasing FAQ
Can two OPC percentages be compared directly?
Only when method, reference standard and reporting basis match. Our quotation process keeps these fields beside the target assay.
How are samples, prices and minimum orders confirmed?
Send the target specification, application, first-order quantity and destination. We respond with sample availability and a quotation for the selected material; quantity, cost, documents and delivery terms are confirmed in writing.
Which quality and certification documents can I request?
Enquire about TDS, the relevant batch COA, SDS and project-specific certification documents. Actual documents are coordinated by material and use, with certificate scope reviewed separately. This page is not a batch test report.
