2901.29.10 - Derived in whole or in part from petroleum, shale oil or natural gas

This HTS category, 2901.29.10, encompasses unsaturated acyclic hydrocarbons that are derived in whole or in part from petroleum, shale oil, or natural gas. These are organic compounds characterized by the presence of carbon-carbon double or triple bonds within an open chain structure. The scope here is broad, covering a variety of unsaturated hydrocarbons not specifically listed elsewhere within the broader acyclic hydrocarbon chapter.

Within the "Other" sub-heading of unsaturated acyclic hydrocarbons, this particular classification, 2901.29.10, is distinguished from its sibling category 2901.29.50.00, which is designated for "Other" unsaturated acyclic hydrocarbons. This distinction implies that 2901.29.10 is intended for a more specific group of unsaturated hydrocarbons not fitting into more narrowly defined categories, yet still distinct from what might fall under the broader "Other" sibling at this level.

This category further breaks down into more specific subcategories. For instance, 2901.29.10.10 specifically covers linear α-olefins within a defined carbon range (C6-C30), provided they are unmixed. The existence of this specific subcategory highlights the HTS system's precision in differentiating similar compounds based on their chain linearity, double bond position, carbon number, and purity. The remaining subcategory, 2901.29.10.50, then captures any other unsaturated acyclic hydrocarbons that fit the parent description but do not meet the specific criteria for linear α-olefins.
