Last updated: August 2026 dataLinear alpha-olefins (LAOs) in the C6–C30 range derived from petroleum or shale are a commercially significant subset of this heading, classified under 2901291010, and are widely used as comonomers in polyethylene production and as inputs for detergent alcohols and lubricant additives. The heading also captures other petroleum-derived unsaturated acyclic hydrocarbons (2901291050) and those from non-petroleum sources (2901295000 and 2901296000). Canada leads US imports under this heading, with South Africa, Brazil, Japan, and Ireland also supplying the market. The petroleum versus non-petroleum origin distinction is a key classification driver at the 10-digit level.

CBP expects importers to demonstrate that the product is derived from petroleum, shale, or similar sources to qualify for the petroleum-origin lines. A manufacturer's affidavit or process description confirming the feedstock origin, along with a product specification sheet, is typically required. Without this documentation, the product may default to the non-petroleum line (2901295000 or 2901296000), which can carry a different duty treatment.
Only petroleum-derived LAOs in the C6–C30 carbon chain range qualify for line 2901291010. Petroleum-derived unsaturated acyclic hydrocarbons outside that chain-length window fall under 2901291050. Products from non-petroleum sources are classified under 2901295000 or 2901296000 regardless of chain length. Importers should confirm the carbon number distribution from the supplier's CoA before filing entry.
