Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported in gaseous form
Physical state (liquid vs gas) determines 2711.19 vs 2711.29 classification.
If butadiene separated >50%
Dominant butadiene content shifts to specific unsaturated hydrocarbon codes.
