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.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If contaminated with cyclopentane >5%
Cyclopentane, a cyclic hydrocarbon, would classify under heading 2902, occurring later numerically.
If imported as liquefied petroleum gas component
Liquefied C5+ hydrocarbons in LPG mixtures fall under Chapter 27 butanes/propane provisions.
If as non-hazardous chemical mixture for consumer use
Mixtures not chemically defined and put up for retail fall outside Chapter 29 scope.

Import Tips & Compliance
• Provide distillation range and Reid vapor pressure specs to confirm purity and classification
• Requires special permits for quantities >1000L due to extreme flammability (flash point -49°C)
• Separate from cyclopentane shipments to avoid commingling with cyclic hydrocarbons
