Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If derived from petroleum distillation without purification
Unrefined polyalkylbenzenes from crude oil remain Chapter 27 hydrocarbons, not Chapter 29 pure compounds.
If ethylbenzene content exceeds specification limits
Presence of ethyl groups may shift to specific ethylbenzene provisions within the same subheading.
