Import Tips
• Provide certificate of analysis confirming ≥99.9% purity to verify classification as chemically defined ethylene,DOT/UN approved gas cylinders required; include safety data sheets (SDS) and pressure test certificates,Avoid misclassification as mixtures - single-component verification essential to prevent Chapter 27 reclassification
