As the international dietary supplement and clean-label cosmetic sectors shift toward strict regulatory compliance under USP, EP, and FDA cGMP criteria, sourcing verified raw materials is crucial. Xi'an Sirn Bio-Tech integrates Shaanxi's biodiversity with university joint laboratories to deliver chromatographic fingerprinted extracts assayed via HPLC, UV, and GC.
2 GMP-compliant production plants operating 4 standardized lines & 2 pilot testing modules.
In-house gas chromatography, UV-Vis, and HPLC release certificates generated for each dispatch.
18 senior biochemical technicians alongside 5 licensed TCM pharmacists driving quality systems.
Active R&D partnerships with Xi'an Jiaotong, Northwest, and Xi'an University of Science and Technology.
Procurement professionals in Europe, North America, and the Asia-Pacific region are navigating regulatory scrutiny, evolving analytical standards, and consumer-led clean label initiatives.
Adulteration with synthetic active compounds or cheaper botanical species is a major audit risk for dietary brand owners. Modern procurement now requires verified testing over generic assay ratios:
Global regulatory bodies like EFSA, US FDA, and Health Canada are continually tightening maximum residue limits (MRLs) across multiple contaminants:
Formulators are moving away from coarse, bitter herbal powders toward functional ingredients engineered for stability, rapid absorption, and pleasant taste:
When evaluating Chinese botanical ingredient exporters, request a full 3-batch COA showing HPLC assay data, residual solvent gas chromatograms, heavy metals via ICP-MS, and real-time microbiological plate counts. This documentation confirms process repeatability before you confirm commercial orders.
Operating from Xi'an, Shaanxi—the hub of Chinese botanical raw material processing—we bring decades of extraction expertise backed by modern pharmaceutical-grade quality systems.
Two industrial plants running 4 standardized high-volume extraction units and 2 pilot development lines facilitate seamless formula scale-up from 1 kg pilot trials to multi-ton commercial production.
Active collaborations with Xi'an Jiaotong University, Northwest University, and Xi'an University of Science and Technology provide direct access to academic instrumentation and chromatographic separation models.
Full OEM/ODM support for custom extraction ratios (10:1, 20:1, 50:1), targeted marker assays (HPLC/UV/GC), specific mesh size granulations (80–200 mesh), and turnkey private-label sachets.
Certified GMP production environment with documented batch-specific trace files, allergen statements, non-irradiated declarations, and rapid 2-hour technical query turnaround times.
Detailed technical, compliance, and supply chain answers covering raw material verification, analytical chemistry, testing protocols, and international logistics.
Our standard MOQ for stock items (such as standardized Cordyceps, Aronia, and Astaxanthin) is 1 kg to support R&D pilot screening and formulation bench trials. For custom ratio extracts or tailored mesh milling, our batch MOQ starts at 25 kg (one standard fiber drum).
Every commercial batch is tested in-house with High-Performance Liquid Chromatography (HPLC), Gas Chromatography (GC), or UV-Vis Spectrophotometry depending on the active compound. We provide batch-matched Certificates of Analysis (COA) along with overlay chromatograms upon request.
We prioritize green processing. Most extracts are isolated using deionized water, food-grade grain ethanol, or supercritical CO₂ fluid (for sensitive lipids like Astaxanthin). We do not use Class 1 chlorinated solvents, ensuring full compliance with USP <467> and EP 5.4 guidelines.
All batches undergo screening via Inductively Coupled Plasma Mass Spectrometry (ICP-MS) to meet strict global thresholds: Lead (Pb) < 1.0–2.0ppm, Arsenic (As) < 1.0ppm, Cadmium (Cd) < 0.5ppm, and Mercury (Hg) < 0.1ppm. Multi-screen pesticide panels align with USP <561> limits.
Yes. While spray drying sugary or hygroscopic juices typically requires 10%–20% maltodextrin or acacia fiber to prevent caramelization in the spray tower, our vacuum freeze-drying process produces 100% pure, carrier-free powders from raw fruit and botanical sources.
Yes. We regularly work with third-party testing institutions such as SGS, Eurofins, and NSF. You are welcome to submit pre-shipment composite lot samples to your preferred independent laboratory for concurrent release testing.
Standard export orders are double-bagged in food-grade polyethylene liners, sealed in multi-layer vacuum heat-sealed aluminum foil bags, and housed inside sturdy 25 kg fiber drums. Desiccant packs and temperature-controlled palletizing are available on request.
Every shipment is accompanied by a batch Certificate of Analysis (COA), Safety Data Sheet (MSDS/SDS), Botanical Flow Chart, Non-GMO Declaration, BSE/TSE Statement, Allergen Matrix, and Phytosanitary Certificate issued by China Customs CIQ authorities.
Yes. We provide complete OEM/ODM formulation services, including dry powder ribbon blending, micron-scale uniform milling (up to 200 mesh), capsule filling, and unit-dose flexible packaging (stick packs, sachets, and retail jars) in certified cleanrooms.
Standard warehouse catalog inventory dispatches within 48 to 72 hours of purchase order validation. Custom production runs typically ship within 10 to 14 business days. We provide global air freight via DHL/FedEx/Air Cargo and FCL/LCL ocean shipping to major global ports.
