About HS Code 284910

This HS code covers calcium carbide, a compound primarily known for its role in generating acetylene gas and its use in metallurgical processes. Historically, it was crucial for carbide lamps and is still vital in many developing economies for welding and cutting applications where acetylene is produced on-site. In modern industry, calcium carbide is extensively used in steelmaking as a desulfurizing agent and as a fuel source. Its trade is driven by the demand from the steel industry, chemical manufacturing (for acetylene-derived chemicals), and welding sectors globally. Exporters are typically countries with access to limestone and coal, the raw materials for its production, while importers are nations with active steel production and fabrication industries. Handling requires care due to its reactivity with water, producing flammable acetylene gas.

Products Under This Code

Calcium carbide lumps, Calcium carbide powder, Acetylene-grade calcium carbide, Desulfurization-grade calcium carbide

Real World Examples

Used in welding gas production, desulfurization in steel mills, carbide lamps

Common Misclassification

Can be confused with other carbides like silicon carbide (284920) or other metal carbides (284990), but 284910 is exclusively for calcium carbide.

Products Classified Under 2849.10

Industry

This code belongs to the Chemicals industry.

Trade Overview

China is the largest producer and exporter, while India, Southeast Asian countries, and parts of Africa are major importers for industrial applications.
