HS Code for Propylene

Propylene, also known as propene, is classified under HS code 2901.22 because it is an unsaturated acyclic hydrocarbon. Chapter 29 of the Harmonized System covers organic chemicals, and heading 2901 specifically addresses acyclic hydrocarbons. Within this heading, the system distinguishes between saturated and unsaturated compounds. Propylene, having a double bond (C3H6), falls under the unsaturated category. For classification under 2901.22, the product must typically meet a high purity threshold, often 95% or more by volume, as defined by the General Explanatory Notes to Chapter 29. If the purity is lower, the product may be diverted to Chapter 27, specifically 2711.14, which covers liquefied propene of lower purity. This classification is critical for global trade as propylene is a fundamental building block in the petrochemical industry, used for producing polypropylene, acrylonitrile, and various oxo alcohols. The classification logic relies on the chemical structure—specifically the lack of a ring structure (acyclic) and the presence of carbon-carbon double bonds (unsaturated). Furthermore, the HS code 2901.22 is reserved for propene that is not mixed with other hydrocarbons beyond the tolerances allowed for chemically pure substances. In the context of international trade, this code ensures that the substance is treated as a chemical feedstock rather than a fuel source. The distinction is vital for tariff application and regulatory oversight, as chemical-grade propylene is subject to different safety standards than fuel-grade liquefied petroleum gas (LPG).

Common Misclassification

Propylene is frequently confused with HS code 2711.14. The distinction lies in the purity level. While 2901.22 is for chemically pure propylene (usually >95%), 2711.14 is for liquefied propene used as fuel or in lower-purity industrial applications. Misclassifying high-purity propylene under Chapter 27 can lead to issues with chemical inventory regulations.

FAQ

What is the HS code for Propylene?

The HS code for high-purity propylene (propene) is 2901.22.

What is the difference between 2901.22 and 2711.14?

The difference is based on purity; 2901.22 is for organic chemicals of high purity, while 2711.14 is for mineral fuels and oils with lower propene concentrations.
