HS v2022 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 through sintering. Tungsten, also known as wolfram, is a highly valuable and versatile metal with a wide range of industrial applications. It is prized for its exceptional hardness, high melting point, and excellent thermal and electrical conductivity. The tungsten industry plays a crucial role in supporting various manufacturing sectors, from construction and machinery to electronics and aerospace.

Production process

The production of unwrought tungsten typically involves a multi-step process. First, tungsten ore is extracted from mines and then processed to concentrate the tungsten content. The concentrated ore is then subjected to chemical treatments to produce tungsten powder or tungsten compounds. These intermediate products are then sintered, a process that involves heating the material to high temperatures without fully melting it, to create the desired unwrought tungsten forms, 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 equipment and machinery for mining, processing, and sintering the metal. Additionally, the industry relies on a skilled workforce with expertise in metallurgy and materials science to ensure efficient and high-quality production.

Production outputs

The primary output of HS code 810194 is unwrought tungsten, including bars and rods obtained through sintering. These products are then consumed by various downstream industries, such as 820713 Interchangeable tools for hand tools, 840991 Parts suitable for use solely or principally with the engines of heading 8407 or 8408, and 850790 (Parts of electric accumulators, including separators therefor, whether or not rectangular (including square)), which utilize tungsten's unique properties in the manufacture of cutting tools, engine components, and electrical equipment.
