Coenzyme Q10 CAS 303-98-0 — China API Manufacturer | ChP/USP/EP/JP R&D to Production

Product Overview & China Manufacturing Landscape

Coenzyme Q10 (CoQ10, ubiquinone-10) is a naturally occurring benzoquinone essential for mitochondrial electron transport and cellular energy production. With CAS number 303-98-0 and molecular formula C59H90O4, CoQ10 serves dual roles as a pharmaceutical API for cardiovascular and mitochondrial disease treatment, and as a high-value nutraceutical ingredient for dietary supplements and functional foods. China has become the world’s dominant CoQ10 producer, with over 15 major manufacturers and combined annual production capacity exceeding 2,500 metric tons — representing approximately 80% of global supply. The Chinese CoQ10 industry has shifted predominantly to microbial fermentation routes, which yield the all-trans natural isomer with superior bioavailability compared to chemical synthesis. Our facility in Inner Mongolia operates one of the largest dedicated CoQ10 fermentation platforms in the world.

Our Manufacturing Process & Facility Standards

Our CoQ10 production employs industrial-scale microbial fermentation using optimized Rhodobacter sphaeroides strains in stirred-tank bioreactors ranging from 50,000 to 200,000 liters. The fermentation process, running 5-7 day cycles, is followed by cell harvesting, solvent extraction, crude CoQ10 isolation, and multi-stage purification via molecular distillation and recrystallization to achieve pharmaceutical-grade purity. The entire post-fermentation processing takes place in our 30,000 square meter production facility with ISO 14644-1 Class 7 cleanroom environments for final crystallization, drying, and packaging. Fermentation parameters including dissolved oxygen, pH, temperature, and nutrient feed rates are controlled by advanced bioprocess control systems with real-time monitoring. In-process controls include HPLC potency checks at extraction and purification stages, trans-isomer ratio verification by HPLC (all-trans content ≥98%), residual solvent analysis, and crystal habit assessment by optical microscopy. Our annual production capacity exceeds 400 metric tons with typical batch sizes of 200-500 kg of finished API per production cycle.

Quality Standards & Multi-Pharmacopeial Compliance

Our CoQ10 is manufactured to meet pharmaceutical-grade specifications per ChP 2020, USP-NF (ubidecarenone monograph), EP 11.0, JP XVIII, and additionally complies with food-grade standards for nutraceutical applications. Typical assay values are 98.0-101.0% on a dried basis. Critical quality parameters include: all-trans isomer content (≥98.0%), related substances by HPLC (total ≤2.0%), residual solvents per ICH Q3C (hexane, ethanol, and ethyl acetate within specified limits), loss on drying (≤0.2%), heavy metals (≤10 ppm by ICP-MS), lead specifically (≤1.0 ppm), microbial limits (total aerobic count ≤100 CFU/g, yeast and mold ≤50 CFU/g, absent for specified pathogens), and melting point range (48-52°C). For dietary supplement applications, we provide additional testing for pesticide residues, aflatoxins, and allergen absence. Complete COA documentation and optional Kosher/Halal certifications are available with every shipment.

Regulatory Documentation & Registration Support

Our CoQ10 regulatory documentation spans both pharmaceutical and nutraceutical regulatory frameworks. Pharmaceutical documentation includes: NMPA drug registration certificate, US FDA Type II DMF, European CEP from EDQM, Japanese DMF, and quality certificates. For nutraceutical/supplement markets, we hold: US FDA GRAS notification status, Novel Food compliance documentation for EU markets, TGA listing support for Australia, and Health Canada NPN support documentation. Our facility maintains FDA establishment registration and has been inspected by US FDA, EU regulatory inspectorates, and Japanese PMDA with successful outcomes. Additional certifications include ISO 22000 (food safety), FSSC 22000, Kosher (OU), and Halal (IFANCA). Our regulatory team supports customers across both pharmaceutical and nutraceutical channels with market-specific documentation, registration strategy guidance, and audit coordination.

Packaging, Storage & Global Logistics

CoQ10 is packaged under nitrogen atmosphere to prevent oxidation, in aluminum foil laminate bags within cardboard drums. Standard pharmaceutical packaging is 1 kg, 5 kg, and 25 kg per unit. For nutraceutical bulk orders, 25 kg and 50 kg drums are standard. Custom packaging including smaller retail-ready portions (100 g, 250 g) is available for supplement companies. Storage conditions require temperatures below 25°C in a dry environment protected from light and air, with validated shelf life of 36 months. We ship to over 60 countries through established logistics networks. Sea freight transit times range from 18-35 days depending on destination, with rail and air options for expedited delivery. Given CoQ10’s sensitivity to oxidation, we ensure all packaging maintains nitrogen atmosphere integrity throughout the supply chain. Our logistics team handles the full scope of export documentation including commercial invoices, packing lists, COA, certificates of origin, and dietary supplement import permits as required by destination markets.

Competitive Pricing & Supply Reliability

As one of China’s largest CoQ10 producers by fermentation, our production scale delivers the most competitive pricing in the global market. Our vertically integrated process — from strain development and fermentation through purification and finished product — eliminates external dependency and enables direct competitive pricing that typically represents 40-60% savings compared to Japanese-origin CoQ10. MOQ is 25 kg for pharmaceutical customers and 100 kg for nutraceutical bulk orders, with smaller evaluation quantities of 1-5 kg available. We offer quarterly pricing indexed to fermentation feedstock costs, annual fixed-price contracts for committed volumes, and special pricing for institutional and government procurement programs. Our 400+ metric ton annual capacity ensures zero allocation constraints. We maintain strategic finished product inventory of 50+ metric tons for immediate availability, with production flexibility to scale output based on demand forecasts provided by customers.
