Polyethylene glycol 3350 (PEG 3350) is a common laxative used in pharmaceutical formulations. The compound's bulk API sourcing is critical for manufacturers to ensure product quality, regulatory compliance, and supply chain stability.
Major Suppliers and Geographic Distribution
Several manufacturers globally produce PEG 3350 API, primarily located in North America, Europe, and Asia. Key suppliers include multinational chemical companies and regional producers.
North American Suppliers
- Dow Chemical (US)
- BASF (Germany with regional facilities)
- Ashland Global Holdings (US)
European Suppliers
- Solvay (Belgium)
- Merck KGaA (Germany)
- Croda International (UK)
Asian Suppliers
- Shandong Chemicals (China)
- Wuxi AppTec (China)
- Mitsubishi Chemical (Japan)
Capacity and Production Endpoints
Manufacturers vary significantly in capacity. Top producers can manufacture tens of thousands of kilograms per month, ensuring steady supply for global markets. Production facilities comply with Good Manufacturing Practice (GMP) standards.

Regulatory Status of API Sources
Supply chains depend on compliance with regional regulations:
- US: FDA-inspected facilities, regulatory filings under Food, Drug, and Cosmetic Act.
- Europe: European Medicines Agency (EMA) standards, GMP certification.
- China/Japan: Local GMP adherence, export licenses.
Many suppliers hold international certifications such as ISO 9001 and ISO 13485, facilitating global distribution.
Quality and Certification Standards
API quality affects downstream formulation performance. Suppliers commonly provide:
- Certificates of Analysis (CoA)
- Certificate of Suitability (CEP) for European markets
- Drug Master Files (DMF) submissions with the FDA
Purity Specifications
- Content: ≥99%
- Residual solvents: Below ICH limits
- Heavy metals: Below 10 ppm
Pricing and Supply Trends
Average API pricing varies with supplier scale and regional factors:
- US suppliers: $20–$30 per kg
- Asian suppliers: $15–$25 per kg
Global supply chain disruptions, such as port delays or raw material shortages, can influence availability and pricing.
Key Considerations for Sourcing API
- Regulatory compliance, especially for export markets
- Production capacity aligned with forecasted demand
- Certification standards (GMP, ISO)
- Lead times from order to shipment (typically 4–8 weeks)
- Raw material sourcing for PEG 3350 production (ethylene oxide, water)
Final Notes
The choice of API supplier depends on regulatory jurisdiction, volume requirements, and cost constraints. Few suppliers dominate the market, with reputable companies maintaining quality and supply stability.
