Bacteriostatic water manufacturers

Bacteriostatic Water for Injection must be a sterile, non-pyrogenic preparation containing 0.9% (9 mg/mL) of benzyl alcohol added as a bacteriostatic preservative. The water must meet USP (United States Pharmacopeia) or EP (European Pharmacopoeia) standards for purity. The pH level should be maintained between 4.5 and 7.0 to ensure stability when used as a diluent for various medications.

Buyers must prioritize suppliers with GMP (Good Manufacturing Practice) certification and ISO 13485 for medical devices or pharmaceutical grade production. It is critical to request a COA (Certificate of Analysis) for every batch to verify the exact concentration of benzyl alcohol and the absence of microbial growth. Ensure the product is labeled for 'Multiple-Dose Use' and check for FDA or CE registration depending on your target market.

The product is typically housed in USP Type I borosilicate glass vials to prevent chemical leaching. Vials should feature flip-off plastic caps and medical-grade rubber stoppers. For shipping, the product must be kept in a controlled room temperature environment (20°C to 25°C) and protected from light. Ensure the packaging includes tamper-evident seals to guarantee product integrity during cross-border transit.

Bacteriostatic water is designed for diluting or dissolving drugs for intravenous, intramuscular, or subcutaneous injection. However, it is strictly contraindicated for use in newborns due to the potential toxicity of benzyl alcohol ('Gasping Syndrome'). It should also not be used for epidural or intrathecal anesthesia. Buyers must ensure their end-users are aware that once a vial is opened, it can be used for up to 28 days if stored correctly.

Bacteriostatic water is often classified as a pharmaceutical product or a medical consumable, which subjects it to strict customs scrutiny. You must ensure the HS Code (typically 3004.90) is accurate. Failure to provide a Medical Device Import License or a Product Registration Certificate can lead to seizure. Always consult with a customs broker to confirm if the destination country requires a prescription-only (Rx) distribution license.

To mitigate financial risk, use secure payment terms such as Letter of Credit (L/C) or platforms like Made-in-China.com that offer trade fulfillment security. Conduct a factory audit or hire a third-party inspector (like SGS or Intertek) to perform a Pre-Shipment Inspection (PSI). This ensures the batch numbers on the COA match the physical goods before the final payment is released.

Since this is a liquid product, it is often flagged as 'sensitive cargo' by airlines. Use freight forwarders experienced in Cold Chain or Medical Logistics. Ensure the shipment is sent via Air Freight with MSDS (Material Safety Data Sheet) documentation to avoid delays. For large volumes, Sea Freight is more economical, but you must use reefer containers if the transit route passes through extreme temperature zones to prevent degradation of the preservative.

Suppliers usually have high MOQs for custom-labeled vials but may offer lower MOQs for neutral 'white-label' packaging. Negotiate based on annual volume rather than a single order to secure a 10-20% discount. Always request that the cost of third-party lab testing be factored into the contract for large-scale procurement to ensure long-term quality consistency.
