Import Tips
• Verify purity certificate showing it's chemically defined malic acid, not a mixture or derivative to avoid reclassification
• Provide documentation confirming food-grade or technical grade status; FDA prior notice required for food use
• Check for stabilizers - per Chapter 29 note (f), added stabilizers are allowed if necessary for preservation/transport
