Dioxazine Violet Color Lake Pigment from Canada
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
