Import Tips
• Include DEA registration if applicable, as lidocaine is a controlled substance precursor; check import permit requirements
• Submit spectroscopic data (NMR, IR) verifying the amide functional group for customs classification
• Avoid common pitfall of classifying as 'finished anesthetic preparation' which shifts to Chapter 30
