Alternative Classifications

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

2901.21.00.00Same rate: 35%

If acyclic mono-unsaturated hydrocarbon

Single double bond compounds like butene classify in preceding 2901.21, not conjugated dienes.

2931.90.30.00Higher: 41.5% vs 35%

If metal-catalyzed derivative

Organo-metallic butadiene complexes fall under heading 2931 organo-inorganic compounds.

Import Tips & Compliance

Submit NMR spectroscopy confirming >99.9% butadiene with <5 ppm isomers

Single-trip ISO tanks preferred over railcars to minimize contamination risk

Pre-clear with FDA if downstream polymer use requires food-contact notification
