Argon Oxygen Decarburized Ferronickel
Argon Oxygen Decarburized (AOD) ferronickel is a refined alloy containing 25-30% nickel with ultra-low carbon content (below 0.03%), produced through an argon-oxygen decarburization process. This product is used primarily in the production of duplex stainless steels, where precise control of carbon and impurities is critical. It falls under tariff item 7202.60.00 as a ferro-nickel alloy, a form of ferro-alloy defined in Chapter 72.
Ferronickel Briquettes 28% Ni
Ferronickel briquettes containing approximately 28% nickel are a compacted form of ferro-nickel, designed for easier handling, transport, and feeding into electric arc furnaces. The briquetting process does not alter the alloy's chemical composition, and it remains a ferro-nickel product under Chapter 72. This product is classified under tariff item 7202.60.00 as a form of ferro-nickel.
Ferronickel Lumps/Pigs 27% Nickel
Ferronickel in lump or pig form, with a typical nickel content of 27%, is a standard product form produced by casting molten ferro-nickel after furnace tapping. This form is widely used by steel mills as a convenient addition to stainless steel melts. It is explicitly included in the scope of ferro-nickel under tariff item 7202.60.00, as Chapter 72 covers ferro-alloys in pigs, blocks, lumps, and similar primary forms.
High-Grade Ferronickel 32-35% Ni
High-grade ferronickel with a nickel content of 32-35% is a premium alloy used in the production of high-performance stainless steels, such as grade 316, where low phosphorus and sulfur levels are essential for quality. This product meets the definition of ferro-nickel under Chapter 72, as it contains iron and nickel in alloy form. It is classified under tariff item 7202.60.00, which covers all ferro-nickel regardless of nickel concentration.
Low-Carbon Ferronickel LC FeNi
Low-carbon ferronickel, containing less than 0.1% carbon and 25-32% nickel, is specifically designed for producing low-carbon stainless steel grades such as 304L. The reduced carbon content is achieved through specialized reduction processes, making it a distinct ferro-nickel product. It falls under tariff item 7202.60.00 as a ferro-nickel alloy, as the carbon level does not affect its classification within heading 72.02.
Standard Ferronickel 25-30% Nickel
Standard ferronickel containing 25-30% nickel and balance iron is produced by smelting laterite nickel ores in electric arc furnaces. This alloy is the primary source of nickel for stainless steel production, providing a cost-effective way to introduce nickel into the melt. It is classified under tariff item 7202.60.00 as ferro-nickel, a type of ferro-alloy defined in Chapter 72.
