Import Tips
• Submit HPLC or GC assay reports proving ≥99% malononitrile content to avoid reclassification as 'other nitriles'
• Declare exact stabilizer content if present; Chapter 29 note (f) allows stabilizers but requires disclosure
• Use UN-approved 4H1 steel drums; improper packaging leads to customs holds under hazmat regulations
