Products classified under HTS 2819.90.00.00
Chromium(III) Oxide Powder
Chromium(III) oxide (Cr2O3) is a green-colored inorganic compound used as a pigment in paints, ceramics, and glass coloring. It falls under HTS 2819.90.00.00 as one of the 'other' chromium oxides and hydroxides not specified elsewhere in heading 2819.
Chromic Acid Anhydride (Chromium Trioxide)
Chromium trioxide (CrO3), also known as chromic anhydride, is a dark red crystalline compound used in chrome plating and as an oxidizing agent. Classified under HTS 2819.90.00.00 as a chromium oxide not covered by other subheadings in heading 2819.
Hydrated Chromium Oxide
Hydrated chromium oxide (Cr2O3·nH2O) is a green pigment used in artistic paints and cosmetics. It qualifies under HTS 2819.90.00.00 as a chromium hydroxide per the heading scope for chromium oxides and hydroxides.
Chromium Dioxide (Magnetic Pigment Grade)
Chromium dioxide (CrO2) used as a magnetic recording material in audio/video tapes. Falls under HTS 2819.90.00.00 as an 'other' chromium oxide compound.
Viridian Chromium Oxide Pigment
Viridian is a hydrated chromium(III) oxide pigment (Cr2O3·2H2O) used in high-quality artists' oil paints. Classified under HTS 2819.90.00.00 as a chemically defined chromium hydroxide.
Chrome Green Pigment (Chromium Oxide Base)
Chrome green pigment composed primarily of chromium(III) oxide blended with other inorganics for durable green color. HTS 2819.90.00.00 applies to the pure chromium oxide component.
Chromium Oxide Sputtering Target
