Import Tips
• Label with exact IUPAC name and structure diagram; customs often challenges aromatic vs aliphatic distinction
• Ship with stabilizer disclosure; anti-dusting agents allowed only if not rendering specific-use per note (g)
• Avoid bulk packaging mimicking mixtures—separate pure compound to prevent 3824 shift
