HTS US: 2953.XX.XXXX
Description
The HTS code 2953 encompasses a broad range of carbides, which are compounds composed of carbon and a less electronegative element, often metals or semimetals. These carbides can be chemically defined or in various physical forms such as powders, lumps, or shaped articles. Carbides are essential materials widely used in industrial processes due to their hardness, thermal resistance, and chemical stability.
Common types include:
- Tungsten Carbide (WC): Known for exceptional hardness and used in cutting tools, abrasives, and wear-resistant applications.
- Silicon Carbide (SiC): Noted for high thermal conductivity and electrical resistance, used in semiconductors and high-temperature ceramics.
- Other Carbides: Such as boron carbide, calcium carbide, and others, each with unique industrial uses.

What is NOT Classified Here?
To ensure accurate classification, exclusions include:
- Carbide-containing tools and articles: Finished tools or articles made from carbides are classified under Chapter 82 or 84 depending on the product type.
- Carbide powders mixed with other compounds: Mixtures where carbides are not the principal component may be classified elsewhere.
- Other carbon compounds: Non-carbide carbon-based chemicals fall under different headings.
Notes
- Industrial Importance: Carbides under this code are critical for manufacturing, mining, electronics, and chemical industries due to their unique physical and chemical properties.
- Duty Rates: Import duties on carbides vary based on the specific type and application. Detailed tariff schedules should be consulted for exact rates.
- Regulatory Compliance: Some carbides, especially those used in electronics, may be subject to environmental or safety regulations during importation.
