Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If industrial grade lacking photographic purity specification
Technical grades without special designation use general derivative subheading.
If primarily classified by toluene-2,4-diamine toluidine function
Different amine function subheadings may apply based on principal characteristic group.
If hydrocarbon derivatives with minimal amine substitution
Earlier hydrocarbon headings might apply if amine functions are secondary.
