Products classified under Tariff item 2819.90.00.00
Chrome Green Pigment (Chromium Oxide Base)
Chrome green pigment composed primarily of chromium(III) oxide blended with other inorganic substances for durable green colouration. The chromium oxide component falls under this tariff item as an 'other' chromium oxide, provided the blend does not render it a separate pigment preparation of Chapter 32.
2819.90.00Chromic 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. It is a chromium oxide not elsewhere specified, falling under this tariff item as 'other'.
2819.90.00Chromium Dioxide (Magnetic Pigment Grade)
Chromium dioxide (CrO2) in magnetic pigment grade, used for audio and video tapes. As a chemically defined chromium oxide not specifically listed elsewhere, it is classified under this tariff item as 'other'.
2819.90.00Chromium Hydroxide Gel
Amorphous chromium(III) hydroxide gel used as a precursor for catalysts and ceramics. Chromium hydroxides are covered by this heading, and the gel form is included as it is a chemically defined compound, even in hydrated or colloidal state.
2819.90.00Chromium(III) Oxide Powder
Chromium(III) oxide powder (Cr2O3), a green inorganic compound used as a pigment in paints, ceramics, and glass colouring. It is a chemically defined chromium oxide falling under this tariff item as 'other'.
2819.90.00Chromium Oxide Sputtering Target
High-purity chromium oxide sputtering targets used for thin-film deposition in semiconductor manufacturing. These are chemically defined chromium oxides in unworked form, falling under this tariff item as 'other'.
2819.90.00High Purity Chromium Oxide for LEDs
Ultra-high purity chromium oxide (99.999% Cr2O3) used for doping optical materials in LED manufacturing. As a pure, chemically defined chromium oxide, it is classified under this tariff item before any processing into optical elements.
2819.90.00Hydrated Chromium Oxide
Hydrated chromium oxide (Cr2O3·nH2O), a green pigment used in artistic paints and cosmetics. As a chromium hydroxide, it falls under this tariff item, provided it is not mixed with other substances that would change its classification.
2819.90.00Nano Chromium Oxide Powder
Nanoparticle chromium(III) oxide powder (20-50 nm) used in advanced ceramics and catalysts. Particle size does not affect classification as a chemically defined inorganic compound, so it falls under this tariff item as 'other'.
2819.90.00Viridian Chromium Oxide Pigment
Viridian chromium oxide pigment, a hydrated chromium(III) oxide (Cr2O3·2H2O) used in high-quality artists' oil paints. As a chemically defined chromium hydroxide, it falls under this tariff item when in pure pigment form.
