Chromium oxides and hydroxides
2 declarable lines
Heading 2819 covers chromium oxides and chromium hydroxides. It is split into two declarable lines: chromium trioxide in 2819.10.00.00 and all other chromium oxides and hydroxides in 2819.90.00.00. Both lines carry a general (MFN) duty rate of 3.7%.
Products in this heading
- Chromium trioxide flakes for plating
- Chromium trioxide granules
- Chrome oxide green powder
- Chromium(III) oxide powder
- Chromium hydroxide powder
- Chromium oxide catalyst grade
- Chromium oxide refractory grade
How to choose the right subheading
- Decide first whether the product is chromium trioxide, which goes in 2819.10.00.00.
- Use 2819.90.00.00 for other chromium oxides and chromium hydroxides, including chrome oxide green and chromium hydroxide.
- Check whether the product is a separate chemically defined oxide or hydroxide rather than a prepared pigment, dispersion, or mixture.
- Check whether the product is a chromium salt such as chromium sulfate or chromium chloride, which belongs in another heading.
Often confused with
- Heading 3206Prepared pigments or dispersions based on chromium oxide
Prepared pigments and pigment preparations are classified outside the separate chemical oxide.
- Heading 2833Chromium sulfate
Chromium sulfate is a salt, not a chromium oxide or hydroxide.
- Heading 2827Chromium chloride
Chromium chloride is a halide salt, not a chromium oxide or hydroxide.
- Heading 7202Ferrochromium
Ferrochromium is a ferroalloy, not a separate chromium oxide or hydroxide.
- Heading 8112Chromium metal
Unwrought chromium metal and chromium articles are classified outside this heading.
Frequently asked questions
What is the HTS code for chromium trioxide?
Chromium trioxide is classified in 2819.10.00.00; the general (MFN) duty rate is 3.7%.
What is the duty on chrome oxide green?
Chrome oxide green, as an other chromium oxide, falls under 2819.90.00.00 and has a general (MFN) duty rate of 3.7%.
How do I classify chromium hydroxide?
Classify chromium hydroxide as an other chromium hydroxide in 2819.90.00.00, with a general (MFN) duty rate of 3.7%, unless it is a prepared pigment or mixture for chapter 32.
