2901.22.00.00 - Propene (Propylene)

This HTS category, 2901.22.00.00, specifically classifies Propene, commonly known as Propylene. Propene is an unsaturated acyclic hydrocarbon with the chemical formula C₃H₆. It is a colorless gas at room temperature and is a fundamental building block in the petrochemical industry, primarily used in the production of polymers like polypropylene, as well as for the synthesis of other organic chemicals.

Distinguishing Propene from its siblings, Ethylene (2901.21.00.00) is the next simplest unsaturated acyclic hydrocarbon with two carbon atoms, while Butene (2901.23.00.00) contains four carbon atoms and its isomers. Other unsaturated acyclic hydrocarbons with more complex structures or multiple double bonds, such as Buta-1,3-diene and isoprene (2901.24), and other unspecified unsaturated acyclic hydrocarbons (2901.29) fall under different sibling codes, highlighting the specificity of this classification to a three-carbon alkene.

As 2901.22.00.00 is a leaf node, there are no further subcategories within this specific classification. Therefore, the focus for classification purposes rests on accurately identifying the substance as Propene (Propylene) based on its chemical structure and common industrial applications. Import and export declarations for this material should align with its identity as Propene, ensuring correct duty assessment and trade compliance.
