Products classified under HTS 3206.49.55.00
Prussian Blue Pigment
Prussian blue is a dark blue iron hexacyanoferrate pigment used in paints, inks, and artist supplies for its intense color and lightfastness. It falls under HTS 3206.49.55.00 as a pigment based on hexacyanoferrates (ferrocyanides). This synthetic inorganic colorant is prized for its historical use in blueprints and modern industrial coatings.
Turnbull's Blue Pigment Preparation
Turnbull's blue, a ferrous hexacyanoferrate pigment used in analytical chemistry stains and inks. Classified in HTS 3206.49.55.00 for hexacyanoferrate-based inorganic coloring matter. It offers a softer blue tone than Prussian blue.
Paris Blue Ceramic Pigment
Paris blue is a refined hexacyanoferrate pigment for high-temperature ceramic glazes and enamels. Under HTS 3206.49.55.00 as other inorganic coloring preparations based on ferrocyanides. Stable up to 1200°C for porcelain decoration.
Hexacyanoferrate Luminophore Powder
Synthetic hexacyanoferrate powder functioning as inorganic luminophore for fluorescent paints and tracers. HTS 3206.49.55.00 specifically includes such preparations chemically defined or not. Emits blue fluorescence under UV light.
Ferrocyanide Printing Ink Pigment
Ferrocyanide-based blue pigment concentrate for offset lithographic printing inks. Classified HTS 3206.49.55.00 as preparation derived from hexacyanoferrates for coloring matter. Offers high rub resistance in publication inks.
