Import Grape Seed Extract — Buy in Bulk from Supplier in China

Shijiazhuang Jianhe Biotechtech Co., Ltd. supplies a fine red‑brown grape seed extract powder that meets a proanthocyanidin content of up to 99 % and polyphenols up to 95 %. The oligomeric proanthocyanidin fraction ranges from 15 % to 40 %. Antioxidant capacity measured by the Brunswick laboratory falls between 8 000 and 18 000 µmol g⁻¹ ORAC. The extract is water‑soluble at 8‑10 g per 100 ml purified water at 25 °C.

The product is produced by water extraction, preserving the activity of flavanols and avoiding organic solvents. Typical moisture content for such powders is kept at or below 5 % to ensure stability, although the supplier does not list a specific value. Particle size is usually milled to 200 µm or less, which is standard for fine botanical extracts. The powder is packed in a paper drum with two inner plastic bags, a net weight of 25 kg per drum, and stored in sealed containers away from moisture and light.

Importers typically use the extract in nutraceutical formulations, functional foods, and anti‑oxidant supplements. The two‑year shelf life under proper storage makes it suitable for medium‑term inventory. Buyers should confirm incoterms, lead‑time and payment terms directly with the supplier, as these details are not disclosed in the listing. Bulk orders are handled on a wholesale basis, with packaging options limited to the drum format described.

Shijiazhuang Jianhe Biotechtech Co., Ltd. is located in the Nanhuoying Developing Zone of Shijiazhuang, Hebei Province, China. The company is listed as an imported‑tier supplier with a harbour trust tier, although response metrics are not currently available, indicating that buyers should verify communication channels before proceeding.

The firm specialises in water‑extracted grape seed extract, emphasizing preservation of proanthocyanidin activity and laboratory‑verified ORAC values. The listing does not provide information on certifications, production capacity or pricing, so interested importers should request a formal certificate of analysis and any relevant quality certifications directly from the supplier.
