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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If commercial mixtures labeled as 'hexanes' with mixed isomers
Pure isomers vs commercial mixtures distinguished; only pure petroleum-derived get 2901.10.40.
If imported as solvent naphtha
Mixtures of hexane isomers in petroleum distillates classified by distillation profile.
If formulated as ready-to-use extraction solvent
Prepared chemical preparations beyond simple hydrocarbons fall into mixtures chapter.

Import Tips & Compliance
• Submit GC-MS analysis confirming >95% n-hexane content and petroleum origin
• Adhere to OSHA permissible exposure limits documentation for worker safety compliance
• Avoid bulk shipments without stabilizer; pure hexane prone to peroxidation

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.
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.
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.
