Obtain DEA registration and import permit due to ephedrine's controlled substance status; include Form 236 in documentation

Provide certificates of analysis confirming ephedrine salt content and pharmaceutical grade purity to avoid misclassification

Watch for FDA prior notice requirements and ensure retail packing to prevent reclassification as bulk chemicals
