Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If higher purity >99% USP grade
Purer forms may qualify for non-quota toluidine subheading if not note 3 restricted.
If impurities exceed 5% making it a mixture
Chemical mixtures not 'separate chemically defined compounds' classify outside chapter 29.
If pre-reacted into dye intermediate
Synthetic organic products used as luminophores or dye intermediates move to chapter 32.
