What is the HS Code for Silicon Carbide?
For international trade, silicon carbide (SiC) is generally classified under the HS Code 2849.20.
HS Code: 2849.20
Product Name: Silicon Carbide
Category: Carbides, whether or not chemically defined
This HS code is widely used in global customs systems, including India, Brazil, the EU, and the United States, for the import and export of silicon carbide used in metallurgy, refractories, abrasives, and industrial applications.

Silicon Carbide (SiC) for Metallurgical Applications
1. Product Features
Silicon carbide supplied by ZhenAn is designed for high-volume metallurgical consumption, particularly for steel mills and foundries that require stable quality, predictable reaction performance, and competitive bulk pricing.
Key advantages include:
Cost-effective alternative to ferrosilicon in steelmaking and foundry processes
High Si and C activity, improving deoxidation efficiency
Lower slag generation, helping reduce production costs
Stable particle size distribution suitable for automated feeding systems
High temperature resistance and excellent chemical stability
Suitable for large-scale industrial consumption with long-term supply contracts
For buyers in India and Brazil, where logistics cost and raw material efficiency directly impact production margins, SiC is often used to reduce FeSi consumption and overall alloy cost.
2. Technical Specifications
Typical metallurgical-grade silicon carbide supplied by ZhenAn:
| Parameter | Specification |
|---|---|
| SiC Content | 88% – 90% |
| Si | 60% – 70% |
| C | 20% – 30% |
| Fe₂O₃ | ≤ 2.0% |
| Size Options | 0–5 mm, 1–10 mm, 10–50 mm |
| Packaging | 1 MT Big Bag / Bulk Shipment |
| Origin | China |
Custom sizes and specifications are available depending on furnace type and steelmaking process.
3. Application Cases
Steelmaking Deoxidation
In electric arc furnace (EAF) and basic oxygen furnace (BOF) processes, silicon carbide can partially replace ferrosilicon as a deoxidizer and alloying agent, helping mills lower alloy cost.
Foundry Iron Production
SiC improves carbon and silicon recovery, stabilizing the chemical composition of molten iron.
Slag Conditioning
In some steel plants, silicon carbide is used to improve slag fluidity and reduce oxygen activity, increasing metallurgical efficiency.
Example – Cost Reduction Case
A steel plant using FeSi 75% partially replaced it with SiC 90%:
FeSi consumption reduced by 15–25%
Alloy cost reduced by 8–12%
Deoxidation efficiency improved due to combined Si + C reaction
Such optimization is common in price-sensitive steel markets such as India and Brazil, where raw material efficiency directly impacts profitability.
4. Frequently Asked Questions (FAQ)
What is the HS code for silicon carbide?
The international HS code for silicon carbide is 2849.20, used globally for customs declaration.
Is silicon carbide cheaper than ferrosilicon?
In many steelmaking processes, SiC can partially replace ferrosilicon, reducing total alloy consumption and lowering costs.
What is the difference between SiC 88% and 90%?
The difference mainly lies in purity and reaction efficiency:
SiC 90% – higher metallurgical efficiency
SiC 88% – more economical for bulk consumption
Both grades are widely used in steel plants depending on cost targets.
What particle sizes are commonly used in metallurgy?
Typical sizes include:
0–5 mm – injection or fine addition
1–10 mm – common steelmaking use
10–50 mm – furnace addition
