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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If blended with other hydrocarbons for gasoline production
Fuel mixtures and motor spirit are specifically provided for in Chapter 27, taking precedence over pure compounds.
If reclassified as butane despite molecular weight
Subheading 2901.10.10 specifically covers butane; improper isomer identification affects duty.
If when imported with organic composite solvents
Organic composite solvents and preparations are excluded from Chapter 29 per note 2(k).

Import Tips & Compliance
• Submit Certificate of Analysis showing ≥95% n-heptane content to validate Chapter 29 classification
• Use IBC totes or drums certified for UN1262 flammable liquids; declare proper shipping name
• Monitor for anti-dusting agents that could invoke Chapter 29 note (g) but avoid use-specific additives
