Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If dispersed in aqueous media for synthetic fiber dyeing
Acid dyes for wool/synthetics use different solvent classification under 3204.11.
If for pigment printing paste applications on textiles
Pigment preparations based on synthetic coloring matter fall under separate subheading.
If chemically bound into plastic masterbatch pellets
Color masterbatches are classified as plastics rather than pure coloring matter.
