What 24.100 includes

• Specular cast iron is defined as an iron-carbon alloy with a manganese content greater than 6% by weight but less than or equal to 30%. Ferroalloys are defined as alloys in ingots, blocks, lumps, or other similar primary forms, commonly used in the iron and steel industry as filler materials for the preparation of other alloys, as deoxidizers, desulfurizers, or in similar uses, and which generally do not lend themselves to plastic deformation; their iron content is greater than 4% by weight, and they differ from pig iron in having a lower iron content.
• The operation of blast furnaces, steel converters, rolling mills, and finishing shops.
• The production of specialty irons through electrolysis.
• The manufacture of primary iron products, such as: - pig iron - blocks - slag - lumps - liquids - ferrous metal in shot and powder form
• The production of: - alloy steel - ingot steel - steel by pneumatic and baking processes - ferroalloys - ingot iron - specular iron - sponge iron
• The manufacture of semi-finished products: - bars - plates - billets - other forms of iron, steel, and alloy steel
• The manufacture of iron, steel, and alloy steel products: - extrusions - forgings - rolled products - drawn products
• The activity of flat rolling, tube rolling, and finishing workshops where products such as the following are obtained: - wires - bars - pipes - sheets - profiles - hollow cast iron profiles with open seams or welded, riveted, or similarly joined - angle pieces - plates - bars - tubes
• Rods, including those for drill bits
• The manufacture of construction materials for railway and tramway tracks, such as unassembled rails.
• The manufacture of steel wire, bars, and profiles by cold drawing.

What 24.100 excludes

• The production of sintered iron ores (subclass 07.100).
• The operation of independent coke ovens (subclass 19.100).
• These same products manufactured by smelting (group 24.3).
• Screws, nails, flanges, wire mesh, and other metal articles (subclass 25.999).
