Import Tips
• Provide detailed chemical analysis (GC-MS, NMR) confirming unsaturated acyclic structure and purity to avoid misclassification as acrylic acid (2916.11)
• Include Safety Data Sheets (SDS) and CAS number (79-41-4) documentation for customs verification
• Ensure stabilizer declaration if present, as per Chapter 29 note (f), to prevent reclassification
