Isopentane (Natural Gas Derived)
Isopentane, a branched saturated acyclic hydrocarbon (2-methylbutane), is extracted from natural gas liquids via fractionation. Classified under HTS 2901.10.40.00 due to its natural gas origin and status as a C5 saturated hydrocarbon beyond butanes. Commonly used in expanding polystyrene foam production.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If synthetic or unspecified origin
Petroleum/natural gas derivation explicitly excludes synthetic or other source hydrocarbons.
If liquefied petroleum gas (LPG) containing isopentane
Natural gas liquids in liquefied form classified under petroleum gases heading.
If unsaturated C5 isomer like isopentene

Import Tips & Compliance
• Include gas processing plant certificates proving natural gas derivation to prevent Chapter 27 misclassification
• Comply with DOT hazardous material shipping (UN 1265); check for anti-static drum requirements
• Test for isomer purity; mixtures with n-pentane >20% may require average classification

n-Pentane (Petroleum Derived)
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.
n-Hexane (Petroleum Refined)
n-Hexane (C6H14) is a straight-chain saturated acyclic hydrocarbon isolated from petroleum naphtha via distillation and molecular sieve purification. It qualifies for HTS 2901.10.40.00 as a petroleum-derived saturated hydrocarbon beyond butanes. Widely used as extraction solvent for oils and in adhesive formulations.
Cyclohexane (Petroleum Derived)
Cyclohexane is a saturated cyclic hydrocarbon derived from benzene hydrogenation using petroleum-based feedstocks. Although cyclic, it falls under HTS 2901.10.40.00 when specified as acyclic-like in petroleum context, but primarily 2902.90; cross-check confirms acyclic saturated for petroleum sources. Used in nylon production.
