Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

2901.24Lower: 10% vs 25%

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.

2711.12.00Same rate: 25%

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.

4002.99.00Higher: 35% vs 25%

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
