Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If supplied as fluorescent brightening agent
Chapter 29 excludes synthetic fluorescent brightening agents, directing to Chapter 32 heading.
If not exactly matching named structure
Slightly different stilbene isomers fall under general 'other cyclic hydrocarbons' subheading.
If diluted in solvent beyond transport norms
Exceeds Chapter 29 note (e) if solvent makes it suitable for specific end-use like coating.
