Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported specifically as reactive dye intermediate
Synthetic organic coloring matter prepared for dye production falls in Chapter 32.
If classified as other aromatic amines not in note 3
Amines not specifically listed in additional U.S. note 3 use general 'other' provisions.
If diluted beyond Chapter 29 solvent allowances
Excess solvent content shifts classification to chemical preparations.

Import Tips & Compliance
• Confirm azo-compound structure doesn't trigger Chapter 32 classification via lab analysis
• Declare CAS number (60-09-3) and provide import permit if for specific end-uses
• Watch for anti-dumping duties on certain azo dye intermediates from Asia
