Products classified under HTS 2901.10.50.00
n-Hexane (99% purity)
n-Hexane is a saturated acyclic hydrocarbon (C6H14) used primarily as a solvent in industrial applications like adhesive manufacturing and extraction processes. It falls under HTS 2901.10.5000 as it is a chemically defined saturated acyclic hydrocarbon, other than butane and isobutane classified elsewhere in the subheading. The product is supplied in stabilized form for safe transport.
Isohexane Solvent Grade
Isohexane, a branched saturated acyclic C6 hydrocarbon, serves as a low-boiling solvent in rubber production, adhesives, and vegetable oil extraction. Classified under HTS 2901.10.5000 as 'other' saturated acyclic hydrocarbons beyond butane provisions. Typically contains anti-static additives for safety per Chapter 29 notes.
Commercial n-Heptane (C7H16)
n-Heptane is a straight-chain saturated acyclic hydrocarbon used as a standard reference fuel and solvent in chromatography and coatings. It qualifies for HTS 2901.10.5000 as a chemically defined C7 saturated acyclic hydrocarbon, 'other' category. Often includes polymerization inhibitors for stability.
2,2,4-Trimethylpentane (Isooctane)
Isooctane, or 2,2,4-trimethylpentane, is a highly branched saturated acyclic C8 hydrocarbon used as a gasoline octane booster and reference fuel. Falls under HTS 2901.10.5000 as 'other' saturated acyclic hydrocarbons. Supplied with trace stabilizers for transport safety.
Pentane (n-Pentane 95%)
n-Pentane is a volatile saturated acyclic C5 hydrocarbon used in blowing agents for foam production and as a solvent. Classified in HTS 2901.10.5000 as other saturated acyclic hydrocarbons. Includes minimal impurities and transport stabilizers per Chapter 29 criteria.
