Import Tips
• Disclose impurity levels (<2% naphthalic acid) in documentation; high impurities risk reclassification as preparations
• Use fiber drums or poly-lined bags per industry standard; improper packaging leads to customs holds
• Confirm CAS 81-84-5 on all docs; mismatches cause delays at entry
