Tungsten (wolfram); unwrought, including bars and rods obtained simply by sintering

HS v2017 Code: 810194

About tungsten (wolfram); unwrought, including bars and rods obtained simply by sintering

hs code 810194 covers the trade of unwrought tungsten, including bars and rods obtained simply by sintering. Tungsten, also known as wolfram, is a rare and valuable metal with a wide range of industrial applications. It is prized for its high melting point, strength, and resistance to wear and corrosion, making it an essential material in various manufacturing and engineering sectors.

Production process

The production of unwrought tungsten typically involves a multi-step process. First, tungsten ore is mined and processed to extract the pure metal. The ore is then crushed, concentrated, and chemically treated to produce tungsten powder. This powder is then sintered, a process of heating and compacting the material without fully melting it, to form the desired shapes such as bars and rods.

Production inputs

The main inputs required for the production of unwrought tungsten include tungsten ore, which is the primary raw material, as well as specialized machinery and equipment for mining, processing, and sintering the metal. Additionally, energy sources, such as electricity or natural gas, are needed to power the various stages of production.

Production outputs

The primary output of hs code 810194 is unwrought tungsten, including bars and rods obtained through sintering. This material is then used as an input for a wide range of industries, such as 820720 cutting tools, 841191 turbine parts, and 851790 electrical components, where its unique properties make it an essential component.
