Import Tips & Compliance
• Provide molecular structure diagram and CAS number (136-92-5) in commercial invoice for CBP verification
• Ensure stabilizer additions don't exceed Chapter 29 note (f) limits to avoid reclassification
• Watch for bulk vs. lab quantities; larger shipments may trigger additional TSCA notifications
