Dioxazine Violet Color Lake Pigment from China

Dioxazine violet is a synthetic organic color lake pigment derived from carbazole dyes, used primarily in paints, inks, and plastics for its high tinting strength and vibrant hue. It falls under HTS 3205.00.50.30 as a violet color lake preparation specified in note 3 to chapter 32, which covers lake-based coloring matter for tinting materials. This classification applies to the precipitated form on an inert substrate like alumina.

Import Tips

Verify the pigment is a true color lake (dye precipitated on substrate) via lab analysis to confirm classification under 3205, avoiding reclassification to synthetic dyes in 3204

Include detailed chemical composition and production process in import documentation, as CBP may request proof it's not a simple dye mixture excluded by chapter note 3

Ensure labeling specifies lightfastness and recommended applications (e.g

industrial coatings) to prevent issues with end-use misclassification
