2711.14.00.20 - Propylene

This HTS classification covers purified propylene, a significant gaseous hydrocarbon. Propylene, also known as propene, is primarily used as a feedstock in the petrochemical industry for the production of polymers such as polypropylene, as well as for manufacturing various chemicals and other industrial applications. Its classification under liquefied petroleum gases underscores its common storage and transport in a liquid state under pressure.

Distinguishing this category from its siblings, 2711.14.00.10 covers ethylene, which has a different molecular structure and distinct industrial uses, most notably in the production of polyethylene. Similarly, 2711.14.00.30 refers to butylene, a group of four-carbon alkenes with applications differing from propylene, and 2711.14.00.40 covers butadiene, a diolefin crucial for synthetic rubber production. While all are olefins and often derived from similar processes, their chemical composition dictates unique classification and end-use applications.

As a leaf node within the HTS structure, 2711.14.00.20 represents a specific, highly refined product. Therefore, there are no further subdivisions under this code. Classification at this level relies on the precise identification of the substance as propylene, ensuring accurate import and export declarations based on its distinct chemical identity and commercial significance within the broader category of liquefied petroleum gases.
