n-Pentane (Petroleum Derived) from China
n-Pentane is a saturated acyclic hydrocarbon (C5H12) derived from petroleum refining processes such as straight-run distillation. 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
