Import Tips & Compliance
• Verify inclusion in additional U.S. note 3 to section VI and obtain FDA approval for veterinary pharmaceuticals before import
• Provide detailed chemical purity certificates and stability data to avoid reclassification as a different amide compound
• Ensure proper labeling as a regulated substance to prevent delays at customs due to safety or identification concerns
