Ferro-alloys; ferro-silicon, containing by weight 55% or less of silicon

HS v2017 Code: 720229

About ferro-alloys; ferro-silicon, containing by weight 55% or less of silicon

HS code 720229 covers ferro-silicon, a critical ferro-alloy used in the production of steel and cast iron. Ferro-silicon is an essential ingredient in the steelmaking process, helping to remove oxygen and improve the strength and ductility of the final product. This industry plays a vital role in supporting the broader metal manufacturing and construction sectors, which are key drivers of economic growth and development.

Production process

Ferro-silicon is produced by smelting iron ore and silicon-containing materials, such as quartz or coal, in an electric arc furnace. The high temperatures in the furnace cause the iron and silicon to melt and combine, forming the ferro-silicon alloy. The molten ferro-silicon is then cast into ingots or crushed into smaller pieces for easier handling and transportation.

Production inputs

The main inputs required for the production of ferro-silicon under HS code 720229 include iron ore, silicon-containing materials (e.g., quartz, coal), and electricity to power the electric arc furnaces. Specialized equipment, such as furnaces, casting molds, and crushing machinery, are also essential for the manufacturing process.

Production outputs

The primary output of this industry is ferro-silicon containing 55% or less silicon by weight, as defined by HS code 720229. This material is then consumed by the 7201 Pig iron and spiegeleisen in pigs, blocks or other primary forms and 7207 Semi-finished products of iron or non-alloy steel industries, which use ferro-silicon to produce various steel and cast iron products.
