Import Tips
• Include detailed spectral analysis (NMR/IR) in documentation to confirm structure and avoid reclassification
• Comply with TSCA pre-manufacture notice if first import into US; pitfall is ignoring EPA inventory status
• Use UN-approved packaging for corrosive solids; declare as UN 3261 to prevent delays
