Verify supplier certifications and licenses. Confirm they meet GMP (Good Manufacturing Practices) standards. Request detailed Certificates of Analysis (CoA) for each batch, specifying active ingredient content, purity, and potential impurities.
Independently test a sample batch from each supplier using a reputable, accredited laboratory. Compare lab results with the provided CoA. Discrepancies necessitate further investigation and potentially rejection of the batch.
Examine packaging integrity. Check for proper labeling, including clear dosage information, expiry dates, and manufacturer details. Damaged or incorrectly labeled products are unacceptable.
Implement a robust tracking system. This ensures complete traceability, from manufacturing to distribution. This system should allow quick identification of any problematic batches. Track temperature during shipping and storage to maintain product stability.
Establish clear return and replacement policies. Define procedures for handling damaged or substandard products. Collaborate with suppliers to ensure prompt resolution of quality issues.
Regularly review and update your quality control procedures. Adapt them to reflect advancements in testing methodologies and evolving regulatory requirements.
