Import Tips
• Provide polymorphic form characterization; nitrate salts prone to FDA scrutiny on crystal form stability
• Include forced degradation studies in submission; common detention cause is insufficient stability data
• Ensure proper nitrate content assay; over 0.1% impurities triggers import alert
