Import Tips
• Verify purity certificate (≥98%) and optical isomer (L-form) via HPLC analysis to confirm classification as a lysine salt
• Include CoA documenting it's not feed-grade; pharma-grade requires DMF filing with FDA
• Avoid misclassification as bulk feed additive (2922.41.00.10); declare intended use in documentation
