Import Tips
• Ensure cylinders or containers meet DOT/UN pressure vessel standards and include proper safety data sheets (SDS)
• Verify purity levels and provide lab analysis certificates to confirm classification as ethylene over 50%
• Avoid misclassification as natural gas liquids by documenting petrochemical production origin
