About zirconium; other than unwrought, n.e.c. in heading no. 8109, containing less than 1 part hafnium to 500 parts zirconium by weight

HS code 810991 covers zirconium products, excluding unwrought zirconium, that contain 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. This code plays a crucial role in the global supply chain, supporting industries that are vital to economic development and technological advancement.

Production process

The production of zirconium products covered under HS code 810991 typically involves a multi-step process. First, zirconium ore is extracted and processed to produce zirconium metal. The metal is then refined and alloyed with other elements, as needed, to achieve the desired properties. Finally, the zirconium is fabricated into various forms, such as sheets, bars, or tubes, through techniques like rolling, forging, or extrusion.

Production inputs

The main inputs required for the production of zirconium products under HS code 810991 include zirconium ore, as well as various alloying elements and specialized machinery for metal processing and fabrication. Additionally, the industry relies on a skilled workforce with expertise in metallurgy, engineering, and manufacturing processes.

Production outputs

Zirconium products covered under HS code 810991 are used in a wide range of industries, including 840110 Nuclear reactors, 690310 Refractory ceramic goods, and 690410 Building bricks. These zirconium-based materials are valued for their high melting point, corrosion resistance, and other desirable properties. The outputs of this industry may also be used as inputs for other HS codes, such as 810930 Zirconium waste and scrap, 810940 Zirconium powders, and 810990 Zirconium, unwrought, among others.
