Import Tips
• Provide certificate of analysis confirming purity and DL configuration to verify classification under 2922.49.4910
• Ensure proper labeling as 'DL-Alanine' distinguishing from L-Alanine to avoid reclassification
• Check FDA import alerts for amino acids; include end-use documentation if for food/supplements
