HS Code 2849 — Carbides for Industrial Applications
This code covers inorganic compounds consisting of carbon and a more electropositive element. These materials are primarily used for their extreme hardness and thermal stability in manufacturing, cutting tools, and metallurgical alloys. Common types include calcium carbide for generating acetylene gas and silicon carbide for abrasives.
What's included
- Calcium carbide
- Silicon carbide
- Tungsten carbide
- Boron carbide
- Aluminium carbide
What's excluded
- Iron carbide (cementite) → use
7201(Iron carbides are classified as pig iron or steel precursors.) - Precious metal carbides → use
2843(Compounds of precious metals take precedence in Chapter 28.)
Common examples
- Tungsten carbide tips for drill bits
- Calcium carbide stones for lamps
- Silicon carbide grinding powder
- Titanium carbide coating material
Frequently asked questions
Is silicon carbide considered a hazardous material?
Generally no, but finely divided powders may require specific safety data sheets (SDS) and dust control measures during transport.
Trade & shipping notes
- Typical duty range: 0% - 5.5%
- Documentation: Requires a Certificate of Analysis (CoA) to verify chemical purity and crystal structure.
- Typical shipping mode: FCL
- Top exporters: China, Germany, Norway

Key takeaway
Classification depends on chemical composition; calcium carbide requires 'Dangerous Goods' handling due to water reactivity.
