Import Tips
• Submit isomer ratio certificates (typically 50/50 cis/trans) to distinguish from 1-butene or isobutylene
• Ensure DOT/UN 1012 classification for 2-butene and proper placarding on transport containers
• Monitor volatility specs against Chapter Note definitions to prevent reclassification as light oils
