Import Tips & Compliance
• Provide salt confirmation via NMR spectrum; pure trimethoprim base may shift to different purity codes
• Include solubility test data (>50mg/ml) to distinguish from insoluble forms under same heading
• Register with FDA CVM before import; unlabeled powders risk quarantine as unapproved new animal drugs
