Zirconium; unwrought, powders, containing less than 1 part hafnium to 500 parts zirconium by weight

HS v2022 Code: 810921

About zirconium; unwrought, powders, containing less than 1 part hafnium to 500 parts zirconium by weight

HS code 810921 covers the trade of unwrought zirconium powders containing less than 1 part hafnium to 500 parts zirconium by weight. Zirconium is a valuable metal with a wide range of industrial applications, from nuclear reactors to ceramic materials. This code is an important part of the broader 810900 Zirconium and articles thereof industry, which plays a crucial role in various manufacturing sectors and contributes significantly to the global economy.

Production process

The production of zirconium powders covered under HS code 810921 typically involves the extraction of zirconium from zircon sand or other zirconium-bearing ores. The extracted zirconium is then refined and processed into a fine powder through techniques such as electrolytic reduction, chemical reduction, or mechanical milling. The resulting powder is carefully controlled to ensure it meets the specific composition requirements of less than 1 part hafnium to 500 parts zirconium by weight.

Production inputs

The main inputs required for the production of HS code 810921 zirconium powders include zircon sand or other zirconium-bearing ores, as well as specialized equipment for extraction, refining, and powder production. Additionally, the process may require various chemicals, energy sources, and skilled labor to ensure the consistent quality and purity of the final product.

Production outputs

The zirconium powders produced under HS code 810921 are primarily used as raw materials in the manufacture of 840140 Nuclear reactors, 690220 Refractory bricks, blocks, tiles and similar refractory ceramic constructional goods, and 848620 Machines and apparatus of a kind used solely or principally for the manufacture of semiconductor devices or electronic integrated circuits. These powders may also be consumed by other industries, such as 840390 Parts of central heating boilers, 854411 Winding wire of copper, and 854420 Coaxial cable and other coaxial electric conductors.
