Import Tips
• Verify purity levels and provide certificates of analysis to confirm it meets chemically defined compound standards under Chapter 29
• Include documentation on end-use (e.g
• feed additive) to avoid misclassification as a pharmaceutical intermediate
• Check for stabilizer additions; ensure they qualify under chapter note (f) without altering general use classification
