Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If ethylenically unsaturated hydrocarbon gas from synthetic sources
Synthetic unsaturated gases may shift to Chapter 27 if not purely chemically defined propene.
If further oxidized to propylene oxide
Derivatives with oxygen functions move to later headings per chapter classification rule.
If heavily diluted or mixed for specific non-chemical use
Preparations not qualifying as chemically defined compounds fall into mixtures of Chapter 38.

Import Tips & Compliance
• Provide gas chromatography reports confirming propene as principal component; comply with HAZMAT shipping regulations (UN 1077); watch for stabilizer additions that could trigger note (f) subclassification
