What botanical extracts do you offer?

Our portfolio spans standardized botanical extracts and naturally derived active compounds at every scale. That includes branded ingredients with proven bioavailability, and tailored OEM/ODM solutions — think custom premixes, stick-pack blends, and ready-to-mix solid beverages.

How does Huaze ensure consistent quality and sustainability?

We’re a manufacturer. Our extraction and formulation facility occupies 4 hectares (60 Mu) in Shaanxi’s Yangling Agricultural Demonstration Zone, operating under ISO 9001 quality management with Kosher and Halal certification. Every batch is produced, tested, and released on-site — we don’t outsource production or skip release testing.We prioritize locally sourced raw materials and partner exclusively with GACP-compliant growers. This gives us full traceability from field to finished product and supports biodiversity conservation. Every batch is identity-verified, purity-tested, and checked for batch-to-batch consistency before release.

Do you provide samples for evaluation?

Yes. We know that in-house validation is a critical step in your R&D process. We typically supply 30 g of product at no charge for evaluation purposes. While the sample itself is free, we ask that you cover the international shipping cost — which is fully creditable against your first bulk purchase order.
