Import Tips
• Submit GC-MS or NMR analysis confirming molecular structure matches named compound for Customs verification
• Declare exact bromine content (typically 68-70%) as it validates chemical identity under this specific HTS
• Package in UN-approved chemical drums; improper packaging leads to hazardous material surcharges
