Mefenamic acid

Mefenamic Acid is a non-steroidal anti-inflammatory drug (NSAID) that must adhere to strict pharmacopeial standards. Buyers should ensure the product complies with USP (United States Pharmacopeia), BP (British Pharmacopeia), or EP (European Pharmacopoeia) standards. Key technical parameters include a purity level (assay) of 98.0% to 102.0%, a melting point between 230°C and 231°C, and strict limits on heavy metals (≤20ppm) and related substances/impurities to ensure safety and efficacy.

For pharmaceutical raw materials (APIs), the supplier must hold a GMP (Good Manufacturing Practice) certificate. Additionally, look for suppliers with a Written Confirmation (WC) for export to the EU, or a CEP (Certificate of Suitability). For quality management systems, ISO 9001 is a baseline, while ISO 14001 indicates environmental compliance. Always request a Certificate of Analysis (COA) for every specific batch before shipment.

Mefenamic Acid is sensitive to light and moisture. It should be stored in well-closed, light-resistant containers at controlled room temperatures (typically 15°C to 30°C). Suppliers should provide stability data indicating the re-test period or shelf life, which is usually 3 to 5 years when stored under optimal conditions. Ensure the packaging uses double-layer PE bags inside fiber drums for bulk transport.

Professional buyers should conduct a factory audit or hire a third-party inspector (like SGS or Intertek). Verify the supplier's Business License and their Drug Manufacturing License. On platforms like Made-in-China.com, prioritize Audited Suppliers who have undergone on-site verification of their production facilities and R&D capabilities.

Pharmaceuticals are highly regulated. The biggest risk is Customs seizure due to lack of proper importation permits or Drug Master Files (DMF). Ensure your local health authority (e.g., FDA in the US, EMA in Europe) has approved the manufacturer. You must confirm the HS Code (typically 2922.43) and ensure all import licenses are active before the goods leave the port of origin.

For high-value chemical orders, avoid 100% upfront payments. Use Letter of Credit (L/C) for large volumes or Escrow services provided by reputable B2B platforms like Made-in-China.com. A common professional structure is 30% T/T deposit and 70% against the Bill of Lading (B/L) after a successful third-party pre-shipment inspection (PSI).

Mefenamic Acid is generally not classified as a dangerous good for transport (non-DG), but you must verify the Material Safety Data Sheet (MSDS). Ensure the freight forwarder provides a Clean Bill of Lading and that the cargo is not co-loaded with hazardous chemicals or food products to prevent cross-contamination. Always opt for door-to-door insurance covering the full invoice value.

Never skip the sample testing phase. Request a 10-50g sample for lab analysis (HPLC testing) before placing a bulk order. Include a Quality Agreement in your contract that specifies the right to return or refund if the bulk shipment's COA does not match the pre-shipment sample or fails third-party laboratory verification upon arrival.
