Import Tips

• Obtain FDA Drug Master File (DMF) and ensure Certificate of Analysis confirms USP purity standards for pharmaceutical-grade imports

• Provide detailed stability data and impurity profiles as required for anti-infective sulfonamides under FDA import alerts

• Avoid common pitfalls by verifying the product meets 'drugs' classification rather than veterinary use which may shift to different HTS
