Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as amino-alcohol rather than amino-phenol
Different oxygen function (alcohol vs phenol) shifts to later subheading within 2922.
If used as synthetic fluorescent brightening agent
Chapter note excludes such products to heading 3204 for synthetic organic luminophores.
If put up in retail packing as prepared photo developer
Prepared chemical preparations for photographic use fall under chapter 38 retail forms.
