HTS US: 2849.XX.XX.XX
Description
Heading 2849 covers a broad range of carbides, irrespective of whether they are chemically defined or not. Carbides are compounds composed of carbon and a metal or metalloid element, known for their hardness and high melting points. This heading includes various carbides primarily used in industrial applications such as cutting tools, abrasives, and refractory materials.
The classification under this heading is broken down by the type of carbide and its physical form, including crude, grains, ground, pulverized, or refined forms.

Detailed Breakdown of Subheadings
The heading 2849 is subdivided into specific codes based on the elemental composition and physical state of the carbide.
| HS/HTS Code | Description | Examples & Notes |
|---|---|---|
| 2849.10.00.00 | Of calcium | Calcium carbide, commonly used in the production of acetylene gas and as a desulfurizing agent in steelmaking. |
| 2849.20 | Of silicon: | Silicon carbides, widely used as abrasives and in high-temperature applications. |
| 2849.20.10.00 | Crude | Unprocessed silicon carbide, straight from manufacturing or mining. |
| 2849.20.20.00 | In grains, or ground, pulverized or refined | Processed silicon carbide in granular, powder, or refined forms, used in abrasives and refractory materials. |
| 2849.90 | Other: | Other carbides not classified under calcium or silicon groups. |
| 2849.90.10.00 | Of boron | Boron carbide, known for extreme hardness and use in armor and abrasives. |
| 2849.90.20.00 | Of chromium | Chromium carbide, used for wear-resistant coatings and tools. |
| 2849.90.30.00 | Of tungsten | Tungsten carbide, highly valued in cutting tools, mining, and industrial machinery. |
| 2849.90.50.00 | Other | Miscellaneous carbides not specified above, including mixed or rare carbides. |
What is NOT Classified Here?
To ensure correct classification, note these exclusions:
- Carbides combined with other chemical substances that alter their main characteristics may fall under different headings.
- Organic carbides or complex organometallic compounds are excluded and classified elsewhere.
- Other carbon compounds such as carbon black or graphite are not included under this heading.
Notes
- Industrial Uses: Carbides under this heading are essential in manufacturing, metallurgy, abrasives, and chemical processes.
- Duty Rates: Duty rates vary depending on the specific 10-digit code and product usage; some may be duty-free or subject to specific tariffs.
- Import Regulations: Some carbides may require special handling or certification depending on their industrial application and origin.
