Import Tips
• Classify based on chemical composition, not concentration; provide assay reports to customs
• Comply with DOT hazmat regulations for liquid oxidizers; pitfall is under-declaring as non-hazardous
• Check for BaP (barium permanganate) confusion if impure, which remains under same heading
