Acyclic hydrocarbons; unsaturated, butene (butylene) and isomers thereof

Heading 2901Acyclic hydrocarbons

Chapter 29: Organic chemicals

Plain-language overview

Use HS-6 290123 when importing or exporting unsaturated butenes, specifically butylene and its isomers. A typical shipment might include 1,000 liters of 1-butene used in chemical manufacturing.

This code applies to unsaturated hydrocarbons, which are crucial in producing various chemicals and plastics. In contrast, HS-6 290124 covers isoprene, another important unsaturated hydrocarbon with different applications.

When classifying under this heading, it's essential to distinguish between butenes and other hydrocarbons. For instance, while HS-6 290125 deals with butadiene, HS-6 290123 focuses solely on butylene and its isomers.

Understanding the specific isomers of butylene is vital for accurate classification. 1-butene and 2-butene, for example, have distinct chemical properties and uses, impacting their classification under this HS code.
