Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used directly as synthetic azo dye coupler
When formulated for specific dyeing applications rather than as pure chemical, it falls under synthetic organic coloring matter in Chapter 32.
If imported as mixture with stabilizers or solvents
Chapter 29 excludes preparations; mixtures for chemical use beyond simple preservation go to Chapter 38 as chemical preparations.
If in salt form like sodium α-naphtholate
Naphthol salts are classified under sugar ethers/esters heading per chapter notes, separate from parent phenols.
