Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as a synthetic organic colouring matter
Synthetic organic colouring matter of heading 32.04 takes precedence over Chapter 29 products when the goods are colouring matters, not separate chemically defined compounds.
If imported in a form put up for retail sale as a dye
Dyes or other colouring matter put up in forms or packings for retail sale are classified in heading 32.12, but synthetic organic colouring matter not elsewhere specified falls in 3204.19.
