Overview
This HTS category, 2901.10.30.00, specifically covers n-pentane and isopentane. These are saturated acyclic hydrocarbons consisting of five carbon atoms. N-pentane is a linear alkane with the chemical formula C₅H₁₂, while isopentane (also known as 2-methylbutane) is a branched isomer with the same chemical formula. These hydrocarbons are typically colorless liquids at standard temperature and pressure, with distinct odors, and are primarily used as solvents, in gasoline blending, and as refrigerants.
This classification is distinct from its sibling category, 2901.10.10.00, which includes ethane and butane. Ethane and butane are saturated acyclic hydrocarbons with two and four carbon atoms respectively. The defining characteristic differentiating 2901.10.30.00 from its siblings is the specific presence of hydrocarbons containing exactly five carbon atoms in their acyclic structure, encompassing both straight-chain (n-pentane) and branched-chain (isopentane) forms.
As this HTS category is a leaf node, there are no further subdivisions or subcategories to introduce. Classification at this level is precise, focusing solely on the identification and containment of n-pentane and isopentane within the broader framework of saturated acyclic hydrocarbons.
