HTS US: 2850.00.00.00
Description
This heading encompasses a diverse group of inorganic chemical compounds known as hydrides, nitrides, azides, silicides, and borides. These substances may be chemically defined or not, but explicitly excludes compounds that are also carbides classified under heading 2849.
These compounds are primarily composed of elements combined with hydrogen (hydrides), nitrogen (nitrides and azides), silicon (silicides), and boron (borides). They have specialized applications in industries such as metallurgy, electronics, and chemical manufacturing due to their unique physical and chemical properties.
Code Hierarchy
- Section VI:
- Products of the Chemical or Allied Industries (Chapters 28-38)
- Chapter 28: Inorganic Chemicals; Organic or Inorganic Compounds of Precious Metals, of Rare-Earth Metals, of Radioactive Elements or of Isotopes
- Heading 2850: Hydrides, nitrides, azides, silicides and borides, whether or not chemically defined, other than compounds which are also carbides of heading 2849.
- US HTS Code (10-digit):
2850.00.00.00– The last digits specify the exact elemental composition.
Detailed Breakdown of Subheadings
The 4-digit HS heading 2850 is further divided into 8-digit and 10-digit codes that specify the compound’s elemental composition:
| HS/HTS Code | Description | Examples & Notes |
|---|---|---|
| 2850.00.05.00 | Of calcium | Compounds containing calcium combined in the form of hydrides, nitrides, azides, silicides or borides. |
| 2850.00.07.00 | Of titanium | Titanium-based hydrides, nitrides, azides, silicides or borides used in specialized metal alloys or chemical processes. |
| 2850.00.10.00 | Of tungsten | Compounds containing tungsten in these forms, often used for their hardness and chemical stability. |
| 2850.00.20.00 | Of vanadium | Vanadium-based compounds within this category, important in alloy production and catalysis. |
| 2850.00.50.00 | Other | Includes all other hydrides, nitrides, azides, silicides, and borides not specified above. |
What is NOT Classified Here?
To prevent classification errors, note the following exclusions:
- Carbides:
- Compounds that are also carbides fall under heading 2849 and are excluded from 2850.
- Organic compounds: This heading covers only inorganic compounds; organic derivatives are classified elsewhere.
- Other chemical compounds: Hydrides, nitrides, azides, silicides, and borides which are part of complex mixtures or preparations may be classified under other headings depending on their composition.
Notes
- Industrial Applications:
- These compounds are widely used in manufacturing processes such as alloy production, electronics semiconductors, and chemical synthesis.
- Duty Rates: Duty rates vary based on the specific 10-digit HTS code and the country of origin. Importers should consult the current USHTS for precise rates.
- Regulatory Compliance: Importers must ensure compliance with environmental and safety regulations as some of these compounds may be hazardous or controlled substances.
