Import Tips
• Submit assay reports showing lactam content >90% to qualify under chemically defined compound provisions
• Include Material Safety Data Sheets detailing stabilizer composition to meet note (f) preservation criteria
• Prevent reclassification to Chapter 38 by documenting stabilizers serve only transport/preservation, not specific end-use
