OEM バイヤー向け FAQ

Q. What is the typical MOQ and lead time for rice bran extract?

Supplier-disclosed industry ranges are 10–50 kg for liquid extract and 5–20 kg for spray-dried powder, with 3–6 week lead times. Because rice bran is a continuous milling byproduct, raw-material supply is year-round; lead time is governed mainly by extraction batch scheduling and standardization to spec rather than by harvest seasonality.

Q. Should buyers specify γ-oryzanol or ferulic acid content on the spec?

Yes. For functional positioning around antioxidant claims, request a quantified γ-oryzanol or total ferulic acid value on the COA, with the analytical method specified (HPLC is standard). Generic 'rice bran extract' lots vary widely in active concentration; cosmetic suppliers can typically standardize to a target specification at modest price premium.

Q. Are organic and non-GMO grades of rice bran extract available?

Yes. Organic JAS-certified rice bran feedstock is available from contract growers in the Niigata, Akita, and Toyama rice-milling belts; cosmetic-grade extracts produced from this feedstock can be supplied with chain-of-custody documentation. Non-GMO declarations are standard for Japanese-origin material as commercial GM rice cultivation is not authorized in Japan. Confirm certification scope (raw material vs finished extract) at RFQ.
