Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If greater than 99% pure and not liquefied for transport
Highly purified acyclic hydrocarbons like butadiene are classified under Chapter 29 as separate chemically defined compounds rather than mixtures or petroleum gases.
If sold as a propane-butadiene mixture for fuel use
Mixtures containing butadiene but primarily propane fall under liquefied propane subheading if butadiene is not the principal component.
If imported as synthetic rubber latex containing butadiene
Butadiene incorporated into polymerized synthetic rubber products shifts classification from raw gases to Chapter 40 rubber materials.

Import Tips & Compliance
• Verify purity exceeds 95% butadiene content via lab analysis for classification; obtain hazardous material shipping certifications (UN 1010); ensure cryogenic storage compliance during transport to avoid reclassification
