Oxides of boron; boric acids
1 declarable lines
Heading 2810 covers oxides of boron and boric acids. It has one declarable line, 2810.00.00.00, with a general (MFN) duty rate of 1.5%. The heading does not cover borate salts, boron carbide, boron nitride, or the boron element.
Products in this heading
- Boric acid powder
- Boric acid flakes
- Boric acid crystals
- Orthoboric acid
- Boron oxide (diboron trioxide)
- Anhydrous boric acid
How to choose the right subheading
- Confirm the product is boric acid or an oxide of boron; heading 2810 has only line 2810.00.00.00.
- Check for a metal cation; borate salts such as borax and perborates are not classified in 2810.
- Check whether the product is a carbide, nitride, boride, or the boron element; those go to other headings.
- Classify prepared mixtures by their full composition and use, not by the presence of boric acid alone.
Often confused with
- Heading 2840Borax (sodium tetraborate)
It is a borate salt, not an oxide of boron or boric acid.
- Heading 2840Sodium perborate
It is a peroxoborate covered by the borates heading.
- Heading 2849Boron carbide
It is a carbide, not an oxide or acid of boron.
- Heading 2850Boron nitride
It is a nitride covered by the heading for nitrides and borides.
- Heading 2804Boron element
The element boron is a nonmetal, not an oxide or boric acid.
