Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If refinery off-gas derived ethylene streams
Petroleum derived unsaturated hydrocarbon mixtures fall under Chapter 27 even for polymer use
If significant saturated hydrocarbon impurities present
Predominant saturated C2 content would classify under earlier acyclic hydrocarbon heading

Import Tips & Compliance
• ICP-MS analysis showing total metals <10 ppb required for peroxide initiator compatibility,Sulfur compounds <0.1 ppm to prevent chain transfer reactions,High-pressure cylinder test certification (DOT 3AA 5000 psi) mandatory
