H Acid Sodium Salt (8-Amino-1-naphthol-3,6-disulfonic Acid Intermediate)
H Acid Sodium Salt (8-Amino-1-naphthol-3,6-disulfonic acid) is an organic intermediate used in the production of azo dyes. Although derived from anthraquinone processes, its sulfonated quinone structure places it under halogenated, sulphonated, nitrated or nitrosated derivatives of ketones and quinones. It is classified here as a sulphonated derivative of a quinone, consistent with the chapter's provisions for dye intermediates.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is presented as an amino-naphthol sulfonic acid rather than a quinone derivative
Amino-naphthol sulfonic acids are classified under amines with oxygen function, which may be more specific depending on the form presented.
If imported as a synthetic organic colouring matter or dye
Synthetic organic colouring matter and dye preparations are classified in Chapter 32, not Chapter 29.
