Zirconium; waste and scrap, containing less than 1 part hafnium to 500 parts zirconium by weight

HS v2022 Code: 810931

About zirconium; waste and scrap, containing less than 1 part hafnium to 500 parts zirconium by weight

HS code 810931 covers zirconium waste and scrap containing less than 1 part hafnium to 500 parts zirconium by weight. Zirconium is a valuable metal with a wide range of industrial applications, including in the production of ceramics, refractories, and nuclear reactors. The trade and processing of zirconium waste and scrap is an important part of the global metal recycling industry, allowing for the recovery and reuse of this valuable material.

Production process

Zirconium waste and scrap is typically processed through a series of mechanical and chemical techniques to recover the pure zirconium metal. This may involve sorting, crushing, and melting the scrap material to separate the zirconium from other impurities. The zirconium is then further refined and purified through processes such as chemical leaching, electrolysis, or vacuum distillation to meet the purity requirements for various end-use applications.

Production inputs

The main inputs required for the processing of zirconium waste and scrap include the scrap material itself, as well as various chemicals, equipment, and energy sources needed for the refining and purification processes. Specialized machinery such as crushers, furnaces, and electrolytic cells are also essential for the efficient recovery and processing of the zirconium.

Production outputs

The primary output of HS code 810931 is purified zirconium metal, which can be used in a variety of industries, including 840110 Nuclear reactors, 690220 Refractory bricks, blocks, tiles and similar refractory ceramic constructional goods, and 690390 Other refractory ceramic goods. The processed zirconium may also be used as an input for other HS codes, such as 810930 Zirconium and articles thereof, unwrought, 810940 Zirconium and articles thereof, wrought, and 810990 Zirconium and articles thereof, other, which cover various forms and products of zirconium.
