Import Tips
• Verify purity levels (typically >99%) via Certificate of Analysis to confirm classification under pure butadiene heading
• Ensure proper DOT/UN 1010 hazardous material documentation and cryogenic storage compliance for gaseous imports
• Avoid misclassification as mixtures; even trace impurities must be documented if exceeding chapter note thresholds
