Import Tips
• Include isomer-specific analytical data (NMR, GC-MS) to confirm classification and avoid reclassification
• Ensure packaging prevents dust formation per UN handling regulations for brominated organics
• Monitor EPA persistence/bioaccumulation data; declare end-use to prevent scrutiny under POPs regulations
