Diclofenac sodium

As a non-steroidal anti-inflammatory drug (NSAID), Diclofenac Sodium must strictly adhere to international pharmacopoeia standards such as USP (United States Pharmacopeia), BP (British Pharmacopoeia), or EP (European Pharmacopoeia). Buyers must verify that the manufacturer holds a valid GMP (Good Manufacturing Practice) certificate and a CEP (Certificate of Suitability) or DMF (Drug Master File) to ensure the chemical purity and safety of the Active Pharmaceutical Ingredient (API).

Key technical parameters include assay content (typically 99.0% - 101.0%), particle size distribution, and solubility. For specific dosage forms like enteric-coated tablets or topical gels, the residual solvents and heavy metal limits must be strictly controlled. Requesting a Certificate of Analysis (COA) for every batch is mandatory to confirm that the product meets the specific formulation requirements of your production line.

Diclofenac Sodium is widely used in the pharmaceutical industry for treating rheumatoid arthritis, osteoarthritis, and acute muscle pain. It is available in various forms including oral tablets, injectable solutions, and topical gels. B2B buyers should select the grade (API vs. Finished Dosage) based on whether they are a pharmaceutical manufacturer or a medical distributor.

Importing pharmaceutical chemicals requires rigorous documentation. For the US market, the facility must be FDA registered. For the EU, REACH compliance and Qualified Person (QP) declarations may be necessary. Always ensure the supplier can provide a Safety Data Sheet (SDS) compliant with the GHS (Globally Harmonized System) to facilitate customs clearance and safe handling.

The primary risks include regulatory non-compliance, purity degradation during transit, and customs seizures. To mitigate these, use professional sourcing platforms like Made-in-China.com to vet suppliers. Ensure the packaging is hermetically sealed and light-protected to prevent oxidation, and always verify the supplier's export license for precursor-related chemicals if applicable.

Utilize Trade Assurance services to protect payments until the goods are verified. It is highly recommended to appoint a third-party inspection agency (like SGS or Intertek) to conduct a pre-shipment inspection and laboratory testing of the specific batch to ensure it matches the approved sample.

Focus on long-term stability and supply chain reliability rather than just the lowest price. Negotiate for staged payments (e.g., 30% deposit, 70% after lab test results) and request stability data reports (long-term and accelerated) to guarantee the shelf life of the Diclofenac Sodium.

Diclofenac Sodium is generally stable but should be shipped in cool, dry conditions. Ensure the shipping agent is experienced in handling Class 9 hazardous materials (if classified as environmentally hazardous) and that all Dangerous Goods (DG) declarations are accurate to avoid port delays. For international trade, CIF or CIP terms are often preferred to ensure the seller covers insurance during the high-risk transit phase.
