Nickel mattes; nickel oxide sinters and other intermediate products of nickel metallurgy
HS v2017 Code: 7501
About nickel mattes; nickel oxide sinters and other intermediate products of nickel metallurgy
HS code 7501 covers a range of intermediate products derived from the processing of nickel. These materials play a crucial role in the broader nickel industry, which is essential for the production of various metal alloys, stainless steel, and other industrial applications. The nickel mattes, oxide sinters, and other intermediates classified under this code are the foundation upon which the downstream nickel supply chain is built, making them a vital component of global manufacturing and trade.
Production process
The production of the materials covered by HS code 7501 typically involves a series of metallurgical processes. Nickel mattes are produced by smelting nickel-bearing ores, concentrates, or other raw materials, often in conjunction with the recovery of other valuable metals like copper or cobalt. Nickel oxide sinters are created through the high-temperature oxidation and agglomeration of nickel-containing materials, producing a more concentrated and stable form of nickel oxide.
Production inputs
The key inputs for the industries covered by HS code 7501 include nickel-bearing ores, concentrates, and other raw materials, as well as the necessary energy sources, such as coal or natural gas, to power the smelting and sintering processes. Specialized equipment, including furnaces, reactors, and material handling systems, are also essential for the production of these nickel intermediates.
Production outputs
The primary outputs of the industries covered by HS code 7501 are nickel mattes, nickel oxide sinters, and other intermediate nickel products. These materials are then further processed and refined to produce pure nickel metal, which is used in the manufacture of 7502 Unwrought nickel, 7503 Nickel waste and scrap, and a wide range of nickel-containing alloys and products classified under other HS codes.
