Import Tips
• Include pharmacopeial compliance certificates and stability data as FDA requires for API imports
• Declare exact CAS number (57-68-1) and purity to match HTS drug specification and avoid general chemical classification
• Watch for common pitfall of mislabeling as veterinary use, which could shift to different regulations
