Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If less than 95% purity or contains significant other hydrocarbons
Liquefied petroleum gases with ethylene as component fall under Chapter 27 as mixtures, not pure compounds
If when imported as chemical preparation with stabilizers or solvents
Chapter 29 excludes mixtures with added substances that affect general chemical use per chapter note (e)

Import Tips & Compliance
• 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
