Import Tips

• Provide certificate of analysis confirming chemical purity and structure as an aromatic amino acid with single oxygen function to avoid reclassification

• Declare exact CAS number (150-30-1 for DL form) and ensure packaging complies with chemical transport regulations (DOT/UN)

• Avoid common pitfall of classifying as protein hydrolysates (3504); this is a separate chemically defined compound per Chapter 29 notes
