Import Tips
• Chemical identity confirmed by CAS 86-28-2; provide HPLC purity certificate (>98%) for proper valuation
• DOT classification as combustible liquid if shipped in solution; bulk powder preferred for lower shipping costs
• Avoid packaging that suggests retail sale (consumer packaging) to prevent Chapter 38 reclassification
