It falls under HTS 2901.10.40.00 as a saturated acyclic hydrocarbon other than methane, ethane, and butanes, specifically sourced from petroleum. Used as a solvent and blowing agent in foam production.

Import Tips

Verify Certificate of Analysis confirming petroleum derivation and purity >95% to avoid reclassification

Ensure proper UN 1265 labeling for flammable liquids; common pitfall is inadequate ventilation documentation

Provide refinery source documentation to distinguish from synthetic isomers under different subheadings
