Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If butylene or butadiene content exceeds minor impurities
Presence of unsaturated butanes shifts classification to specific liquefied olefins.
If for unsaturated branched hydrocarbons in pure form
Chemical-grade isobutane without petroleum context enters Chapter 29.
If sold as part of foam-blowing agent kits for retail
Packaged with applicators for consumer use, it becomes machinery parts under Chapter 84.
