U.S. exports of Saturated Acyclic Hydrocarbons (Ethane, Butane, Pentane, and Others) (HS 290110) totaled $745.2M in August 2026.
Importers of Saturated Acyclic Hydrocarbons (Ethane, Butane, Pentane, and Others) paid $451K in duties in August 2026, an average duty rate of 0.58% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Saturated Acyclic Hydrocarbons (Ethane, Butane, Pentane, and Others) imports of $78.0M in August 2026 ran 74% above the year-to-date monthly average of $44.8M.
Last updated: August 2026 dataEthane, n-butane, isobutane, n-pentane, and isopentane are the principal saturated acyclic hydrocarbons in this heading, serving as feedstocks for petrochemical crackers, refrigerant blends, aerosol propellants, and natural gasoline blending. The US schedule separates ethane and butane isomers (2901101010, 2901101020, 2901101030) from pentanes (2901103000) and other saturated hydrocarbons (2901104000, 2901105000, 2901106000), with a dedicated line for material not derived from petroleum, shale oil, or gas. Canada dominates US imports under this heading, reflecting integrated North American natural gas liquids infrastructure, with Germany, South Korea, France, and Spain supplying specialty or non-petroleum-derived grades.

HTS 2901105000 captures saturated hydrocarbons produced through non-fossil routes — such as bio-based or synthetic processes. This distinction can affect duty treatment and is increasingly relevant as bio-based ethane and butane enter commerce. Importers must be prepared to document the production process and feedstock origin to support classification under this line versus the petroleum-derived lines.
N-butane (2901101020) and isobutane (2901101030) are structural isomers with distinct physical properties and end uses: n-butane is primarily used in gasoline blending and LPG, while isobutane is a preferred refrigerant blend component and aerosol propellant. Correct isomer identification on entry documents is essential because misclassification between these lines can trigger CBP penalties and complicate downstream regulatory compliance for refrigerant applications.
