Liquefied Propylene (Polymer Grade)
Polymer-grade liquefied propylene (C3H6) is high-purity propylene liquefied under pressure, used mainly for polypropylene resin manufacturing. Classified under HTS 2711.14.00 due to its status as liquefied unsaturated hydrocarbon gas.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If 99%+ pure and vaporized/non-liquefied
Pure propylene as a separate chemical in Chapter 29, excluding liquefied petroleum gases.
If for refinery-grade propylene with higher impurities
Less pure grades from petroleum refining may classify under butanes if mixture composition shifts.
If mixed with catalysts for immediate polymerization use
Mixed chemical preparations for specific industrial processes fall under Chapter 38.

Import Tips & Compliance
• Provide polymerization-grade specification sheets showing low impurities like sulfur or moisture
• Use ISO tank containers certified for cryogenic liquids with proper venting systems
• Declare exact composition to prevent reclassification as lower-grade fuel propylene
