HTS US: 2810.00.00.00
Description
Heading 2810 includes chemical substances primarily composed of oxides of boron and boric acids. These compounds are widely used in industrial, chemical, and manufacturing processes due to their unique properties such as antiseptic, flame-retardant, and buffering capabilities.
The substances classified under this heading are typically pure chemical compounds or preparations containing boron in oxidized forms. They are essential raw materials in glass production, ceramics, agriculture (as micronutrients), and various chemical syntheses.

Detailed Breakdown of Subheadings
The heading 2810 is generally not subdivided into more detailed 6-digit or 10-digit subheadings in the HTSUS. The full code 2810.00.00.00 covers all oxides of boron and boric acids including various forms and purities.
| HS/HTS Code | Description | Examples & Notes |
|---|---|---|
| 2810.00 | Oxides of boron; boric acids | This includes boron trioxide (B2O3), boric acid (H3BO3), and related compounds. Commonly used in antiseptics, flame retardants, glass and ceramics manufacturing. |
2810.00.00.00 |
Oxides of boron; boric acids | All forms and grades of boron oxides and boric acids classified here. |
What is NOT Classified Here?
To avoid misclassification, note these exclusions:
- Other boron compounds: Boron carbides, boron nitrides, and other boron compounds not specifically oxides or acids are classified elsewhere.
- Organoboron compounds: Organic derivatives of boron fall under Chapter 29 (Organic chemicals).
- Prepared chemical mixtures: Mixtures containing boron oxides as minor components may be classified in other headings depending on their nature.
- Borax and other boron salts: While chemically related, some boron salts have distinct classifications outside heading 2810.
Notes
- Uses: Boric acid and boron oxides are important in the manufacture of fiberglass, borosilicate glass, flame retardants, and as antiseptics in pharmaceuticals.
- Import Regulations: Importation may be subject to chemical safety regulations and environmental controls depending on the country.
- Tariff Rates: Duty rates vary by country and may depend on purity, form, and intended use; check the current USHTS and trade agreements.
