Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If liquefied (LPG)
Liquefied propane falls under 2711.12 as Propane, liquefied, regardless of purity, shifting from gaseous state subheading.
If purity below 90% and other petroleum gas mix
Mixtures with less than 90% propane purity are classified as 'other' gaseous petroleum gases under 2711.19.
If chemically purified for industrial solvents
Saturated acyclic hydrocarbons like high-purity propane used as solvents move to Chapter 29 organic chemicals.

Import Tips & Compliance
• Verify purity certification via lab analysis reports meeting the 90% liquid volume percent standard to avoid reclassification
• Ensure proper hazardous material declarations (UN 1978) and compliance with DOT/49 CFR transport regulations for gaseous hydrocarbons
• Obtain end-use certificates if destined for non-fuel applications to prevent duty drawbacks or penalties
