China iohexol manufacturers

Iohexol is a non-ionic, water-soluble radiographic contrast medium. When sourcing, you must ensure the product complies with international pharmacopoeia standards such as USP (United States Pharmacopeia), EP (European Pharmacopeia), or ChP (Chinese Pharmacopeia). Key technical parameters include purity levels (typically ≥98% or ≥99%), heavy metal content (<10ppm), and bacterial endotoxins (<0.01 EU/mg). For finished injections, verify the iodine concentration (e.g., 140, 240, 300, or 350 mgI/mL) to match specific clinical imaging requirements like CT or angiography.

Due to the medical nature of the product, the supplier must hold a valid GMP (Good Manufacturing Practice) certificate. For international trade, prioritize manufacturers with CEP (Certificate of Suitability to the monographs of the European Pharmacopoeia) or a US FDA DMF (Drug Master File) number. These certifications guarantee that the production process and quality control systems meet rigorous global pharmaceutical standards.

Iohexol is sensitive to light and secondary radiation. It must be stored in secondary packaging that protects it from light at temperatures below 30°C (86°F). During cross-border transit, ensure the logistics provider uses temperature-controlled environments and avoids exposure to X-rays or other ionizing radiation, which can degrade the molecular structure and affect its efficacy as a contrast agent.

Iohexol is widely used for intravascular administration in adult and pediatric cardioangiography, cerebral angiography, and intravenous urography. It is also utilized for body cavity imaging, including myelography and CT enhancement. Its low osmolality makes it a safer alternative to ionic contrast agents, significantly reducing the risk of adverse reactions in patients.

The primary risk involves import license compliance. Pharmaceutical products are strictly regulated; buyers must ensure they have the necessary Import Permits for Drugs required by their local health authorities (e.g., FDA in the US or EMA in Europe). Failure to provide these documents will lead to customs seizure. Always verify the supplier's Export License and ensure all MSDS (Material Safety Data Sheets) are accurately translated and included.

Utilize secure sourcing channels like Made-in-China.com, focusing on Audited Suppliers who have undergone third-party verification (e.g., SGS or Intertek). For payment, use Escrow services or Letters of Credit (L/C) to ensure funds are only released upon verification of shipping documents. It is highly recommended to appoint a third-party inspector to conduct a Pre-Shipment Inspection (PSI) to test the batch purity and packaging integrity before the balance is paid.

Price for Iohexol API is often tied to the global price of raw Iodine. When negotiating, discuss long-term supply contracts to hedge against price volatility. For bulk orders (e.g., >500kg), buyers can typically negotiate a 10-15% discount. Additionally, ask for tiered pricing based on annual volume rather than single-order volume to secure better rates while managing your own inventory levels.

For API (powder form), Air Freight is preferred to minimize the time in transit and reduce exposure to fluctuating environmental conditions. For large volumes of finished liquid injections, Sea Freight with Reefer Containers (Refrigerated) is more economical but requires strict monitoring. Ensure the shipping terms (Incoterms) are clearly defined; CIF (Cost, Insurance, and Freight) is often preferred for medical goods to ensure the supplier handles the complex insurance requirements for high-value pharmaceuticals.
