Import Tips
• Verify purity certificate (≥99%) to confirm classification as chemically defined inositol under Chapter 29, not mixtures
• Include COA and stereoisomer specification (myo-form) in documentation to avoid reclassification as Chapter 29 mixtures
• Ensure bulk packaging without additives; retail-packed supplements may shift to Chapter 30
