💬 Sourcing FAQs

Frequently Asked Questions by B2B Procurement Officers

Clear answers regarding assay specifications, extraction solvents, compliance standards, and MOQ policies.

What is the exact botanical origin and active assay in your Grapefruit Peel Extract?
Our Grapefruit Peel Extract is derived strictly from dried rinds of Citrus paradisi Macf. or Citrus grandis (L.) Osbeck. We standardize active assays across multiple customer specifications, including Naringin 98% HPLC, Citrus Bioflavonoids 45%-80% UV/HPLC, and customized ratios with full chromatography documentation.
Do you provide free testing samples and corresponding lot COAs before placing bulk orders?
Yes. We supply 20g to 50g complimentary evaluation samples along with the actual lot COA and technical documentation for qualified formulation labs, R&D teams, and enterprise purchasing divisions.
What is the Minimum Order Quantity (MOQ) and standard delivery lead time?
Our standard commercial MOQ is 25kg (1 drum). For pilot trial production and laboratory research, we support smaller initial evaluation batches starting at 1kg. Standard orders ship within 3 to 7 business days from confirmed PO.
How do you ensure heavy metal and residual solvent compliance for North American and European imports?
Each batch is tested under USP <232>/<233> and EP limits for elemental impurities (Lead, Arsenic, Cadmium, Mercury) and EP <5.4> / USP <467> for residual solvents. We operate strictly with hydro-ethanolic extraction, completely excluding toxic Class 1 & 2 industrial solvents.
